An aftermarket modification designed to elevate the chassis of a specific vehicle model from 1987 is the focus. These components typically consist of springs, shocks, and potentially other hardware that collectively increase the ride height of the vehicle. For example, installing such a system can increase the clearance between the vehicle’s undercarriage and the terrain.
The installation of these systems provides numerous advantages. Increased ground clearance allows for improved off-road capability, enabling the vehicle to navigate uneven terrain and obstacles more effectively. Furthermore, it provides additional space for larger tires, which can further enhance traction and off-road performance. Historically, such upgrades were often sought by off-road enthusiasts seeking to enhance their vehicle’s capabilities.
The subsequent sections will delve into specific aspects such as component selection, installation considerations, potential impacts on vehicle handling, and other relevant details pertaining to this type of modification.
1. Spring Rate Adjustment
The tale of modifying a 1987 Toyota 4Runner often begins with ambition: the desire to conquer trails previously deemed impassable. But ambition alone is insufficient. The stock suspension, designed for a balance of on-road comfort and light off-road use, quickly reveals its limitations once the terrain becomes challenging. It is here that the concept of spring rate adjustment enters the narrative, becoming a pivotal character in the story of the modified 4Runner. For a lifted 1987 4Runner, the original springs are inadequate to support added weight from off-road accessories or the constant stress of harsher terrain.
Increasing the spring rate is not a simple matter of swapping components. It’s a calibration process, a calculated trade-off. Stiffer springs resist compression more strongly, which means the vehicle rides higher and can handle heavier loads without sagging. This is critical for maintaining the intended lift height of the system. If the spring rate is too low, the modification fails to achieve the intended lift or provide sufficient support. If the spring rate is excessively high, the ride quality deteriorates dramatically, transforming the once compliant 4Runner into a jarring experience on even mildly uneven surfaces. A real-world example: a 4Runner with a winch and heavy bumper requires significantly higher spring rates than a 4Runner intended primarily for visual enhancement. Choosing springs without consideration leads to wasted investment and reduced drivability.
In conclusion, spring rate adjustment is more than a technical specification; it is a core element of the 1987 Toyota 4Runner lift process. Careful consideration of the vehicles intended use and any additional weight is essential for achieving a balanced and functional outcome. The wrong selection can result in a disappointing outcome, but the proper adjustment enables the vehicle to realize its full potential, capable of traversing challenging terrain with confidence and control. Without an adjusted spring rate, the ambition of the modification fails to become a true achievment.
2. Shock absorber selection
The story of a lifted 1987 Toyota 4Runner is as much about control as it is about height. The elevation achieved is only valuable if the vehicle remains stable, predictable, and comfortable, both on the road and on the trail. This is where shock absorber selection enters the narrative. A lifted 4Runner without properly matched shocks is like a ship without a rudder. The springs may provide the desired height, but the shocks dictate how that height is managed, controlled, and ultimately, enjoyed. Imagine a scenario: a 4Runner, newly lifted, attempting to navigate a washboard road. Without adequate damping, the vehicle bounces uncontrollably, its tires losing contact with the surface. Steering becomes imprecise, braking distances increase, and the occupants are subjected to a jarring, unpleasant ride. This is the direct consequence of neglecting the pivotal role of shock absorbers.
The challenge lies in understanding the nuances of shock absorber technology and matching them to the specific characteristics of the lifted 4Runner. Longer shocks are needed to accommodate the increased suspension travel afforded by the lift, but length is only one parameter. Damping force, the shock absorber’s resistance to compression and extension, is equally crucial. A shock absorber with insufficient damping will allow excessive body roll during cornering and contribute to the aforementioned bouncing on rough surfaces. Conversely, a shock absorber with excessive damping will create a harsh, unforgiving ride, transmitting every imperfection in the road directly to the chassis. An example of careful selection: Bilstein 5100 series shocks are a common choice for lifted 4Runners due to their adjustable damping and robust construction, designed to handle the rigors of off-road use while maintaining reasonable on-road comfort.
In essence, shock absorber selection is not merely an ancillary consideration but an integral part of the lifting process. Its the element that transforms a lifted 4Runner from a potentially unstable, uncomfortable machine into a capable and enjoyable vehicle. Careful matching of shocks to the spring rate and intended use ensures that the benefits of the increased ride height are fully realized, providing enhanced off-road capability and a comfortable, controlled ride in all conditions. Neglecting this step undermines the entire undertaking, leaving the 4Runner compromised and its potential unrealized.
3. Extended brake lines
The tale of elevating a 1987 Toyota 4Runner takes an important turn when the topic shifts to brake lines. While the increased ground clearance and imposing stance are visually apparent results of the modification, the necessity of extended brake lines often remains an unsung consideration. The original brake lines, designed for the factory suspension geometry, become a critical constraint once the chassis rises. These lines, constructed from rubber or braided steel, provide the vital hydraulic connection between the master cylinder and the brake calipers. Elevating the body on its suspension stretches these lines beyond their intended range. Visualize a scenario: a lifted 4Runner articulates its suspension over a rock obstacle. As the axle droops, the brake line strains, pulling taut. Repeated stress cycles eventually weaken the line, potentially leading to catastrophic failure. The consequence is a loss of braking power, a perilous situation, especially on challenging terrain or during emergency stops.
The solution lies in replacing the factory lines with extended versions. These longer lines provide the necessary slack to accommodate the increased suspension travel without subjecting the lines to undue stress. The selection of extended brake lines should not be arbitrary. They must be of sufficient length to handle the full range of suspension articulation, even under extreme conditions. The materials used in construction are also paramount. Braided stainless steel lines offer superior durability and resistance to expansion compared to rubber lines, resulting in a firmer pedal feel and improved braking performance. An illustration of proper implementation: A 4Runner equipped with a six-inch suspension lift necessitates brake lines several inches longer than stock. Failure to install these extended lines can result in immediate damage to the original lines or, more insidiously, gradual degradation that ultimately leads to failure at the most inopportune moment.
In summary, extended brake lines are not an optional accessory; they are an essential component of a comprehensive upgrade for a 1987 Toyota 4Runner. They represent a vital safety measure, ensuring that the vehicle’s braking system can function reliably throughout the full range of its modified suspension. Overlooking this aspect can transform a well-intentioned project into a dangerous undertaking, underscoring the importance of meticulous attention to detail when modifying a vehicles suspension system. The story of a successful lift is, in many ways, a story of carefully considered details like this.
4. Driveline angle correction
When a 1987 Toyota 4Runner’s chassis rises, a silent but critical drama unfolds beneath its frame. It’s a tale of angles, vibrations, and the delicate balance of mechanical harmony. Driveline angle correction is not merely an afterthought; its a crucial chapter in the story of modifying this classic off-roader, impacting reliability and longevity.
-
Transfer Case Drop Kits
Imagine the transfer case, the heart of the 4Runners four-wheel-drive system. Lifting the vehicle without addressing the driveline angles introduces stress to the U-joints connecting the transfer case to the axles. A transfer case drop kit lowers the transfer case, lessening the severity of these angles. Without it, the U-joints operate beyond their design parameters, leading to premature wear and potential failure. An example: a lifted 4Runner, vibrating intensely at highway speeds, a symptom often traced back to uncorrected driveline angles after lift kit was installed.
-
Shimming Axles
Another protagonist in this narrative are axle shims. These simple yet effective wedges are inserted between the axle and the leaf spring perches, subtly altering the pinion angle. The goal is to align the pinion with the driveshaft, minimizing the operating angle of the U-joint. Failure to shim can result in vibrations, noise, and decreased U-joint lifespan. Consider a 4Runner experiencing a persistent humming noise that gets worse with increased speed, often an indicator of improper pinion angle.
-
Longer Slip Yokes
The slip yoke, acting as a sliding joint in the driveshaft, allows for changes in length as the suspension articulates. When lifting a 4Runner, the driveshaft may not have sufficient slip travel. A longer slip yoke provides the necessary extension, preventing binding and potential damage. A lifted 4Runner experiencing a clunking sound upon acceleration or deceleration could indicate that the slip yoke is maxing out its travel.
-
Double Cardan Driveshafts
For more extreme lifts, a double cardan driveshaft becomes a necessary investment. Unlike a traditional U-joint, a double cardan joint can operate smoothly at steeper angles. Replacing the factory driveshaft with a double cardan unit significantly reduces vibrations and stress on the drivetrain. Imagine a 4Runner, with a significant lift kit installed, attempting to navigate difficult terrain without this critical component, the resultant vibrations making the experience unpleasant.
These methods, while varied, share a common objective: restoring the driveline geometry to a state that promotes longevity and reliability. The integration of these solutions are very necessary for proper installation of the 1987 Toyota 4Runner lift kit. Driveline angle correction is not a mere add-on; it’s an intrinsic aspect of lifting a 1987 Toyota 4Runner, ensuring that the vehicle’s newfound height does not come at the expense of its mechanical integrity.
5. Steering geometry impact
The narrative of modifying a 1987 Toyota 4Runner takes a complex turn when considering the impact on steering geometry. The act of lifting the chassis, while visually striking and functionally advantageous for off-road pursuits, fundamentally alters the intricate relationships within the steering system. Components designed to operate within a narrow range of angles and distances are now forced to function outside of these parameters. The consequence of neglecting this interplay can manifest as diminished handling, increased tire wear, and, in extreme cases, compromised safety. Imagine a scenario: a newly lifted 4Runner, rolling off the lift with an imposing stance, quickly reveals an unsettling characteristic on the open road a wandering steering feel, demanding constant correction to maintain a straight course. This unsettling characteristic is often a direct result of altered steering geometry.
Specifically, lifting a 4Runner disrupts the factory-set angles critical for proper steering function, most notably the caster angle. Caster, in essence, provides the self-centering force that allows the steering wheel to return to center after a turn. When the suspension is lifted, the caster angle is often reduced, resulting in a lighter, less stable steering feel, prone to wandering. The effects extend beyond merely an altered driving experience. Incorrect steering geometry can accelerate tire wear, particularly on the outer edges, as the tires scrub against the road surface during turns. The solutions to this problem involve aftermarket components designed to restore the steering geometry to within acceptable tolerances. Drop brackets reposition the steering linkage, while adjustable ball joints or control arms allow for fine-tuning of the caster and camber angles. Consider a 4Runner equipped with a properly installed lift kit, but lacking these corrective components. Despite the enhanced off-road capability, the driver faces increased challenges on pavement, fighting a constant battle to maintain control.
In summary, the steering geometry impact of a modification on a 1987 Toyota 4Runner is a critical element often overlooked. The effect of the lift has a compounding effect on other components. Addressing steering geometry is not merely a matter of restoring comfort; it is a fundamental safety consideration. The success of the vehicle’s upgraded off-roading components hinges on a holistic approach that considers every modification as part of an integrated system. A failure to appreciate and correct these alterations transforms the vehicle to be in more disarray, hindering enjoyment, and increasing risks.
6. Tire clearance gains
The story of the lifted 1987 Toyota 4Runner is one of aspiration; the quest for enhanced off-road capability. A fundamental aspect of this transformation, inextricably linked to the chassis elevation, is the attainment of increased tire clearance. A modification, in its essence, is designed to provide the necessary room to accommodate larger, more aggressive tires than the factory configuration allows. The original tire dimensions, carefully chosen by Toyota engineers for a balance of on-road comfort and modest off-road performance, quickly become a limiting factor for those venturing into more challenging terrain. Imagine a 4Runner attempting to navigate a rutted trail, its stock tires struggling for traction, repeatedly contacting the fender wells, and hindering forward progress. This scenario is precisely what the tire clearance gains seeks to remedy. The lift provides the vertical space required to install larger tires, increasing the contact patch with the ground and providing improved grip on loose surfaces, over obstacles, and in muddy conditions. The impact of this change is tangible: improved off-road performance and enhanced aesthetics.
The relationship between the modification and larger tires is a careful balance. The simple installation of a larger tire will not necessarily lead to any beneficial value. Selection of tires should not come before the lift. Tire height and width need to be considered. The overall diameter should not interfere with the operation of any suspension components. The enhanced clearance must also be used wisely and judiciously. While a 4Runner lifted to accommodate oversized tires might conquer challenging trails, it also raises the vehicle’s center of gravity, potentially affecting on-road stability. An illustrative example: a 4Runner equipped with a modification and excessively large tires might excel in rock crawling but exhibit increased body roll during highway maneuvers, requiring a cautious driving style.
In conclusion, tire clearance gains are a pivotal element in the narrative of a lifted 1987 Toyota 4Runner. It represents a gateway to improved off-road performance and opens up a world of tire choices to match the terrain. The success is determined on the overall effect that is achieved between components and what they offer. The increased clearance allows the 4Runner to overcome obstacles and navigate rough terrain, transforming it from a capable vehicle into a more competent one.
7. Off-road capability

It is a desire to transcend the limitations of the factory configuration and unlock the vehicle’s potential to conquer challenging terrain. A modification focused on enhancing the vehicles capability is a key strategy toward the overall goal, not merely for cosmetic elevation.
-
Articulation Improvement
Articulation, the suspension’s ability to flex and maintain contact with the ground over uneven surfaces, is dramatically improved. A greater range of motion allows the tires to conform to the terrain, maximizing traction. Without adequate articulation, the 4Runner may lift a wheel in the air, losing valuable grip. An example of improved articulation in use is that the vehicle is able to transverse obstacles in a diagonal manner.
-
Increased Approach and Departure Angles
The ability to approach and depart steep inclines without damaging the front or rear of the vehicle is crucial for serious off-roading. Enhancing this capability increases the vehicle’s angles to easily scale a slope. A 4Runner with improved departure angles can descend a steep decline without scraping the rear bumper.
-
Larger Tire Accommodation
The modification allows for the installation of larger, more aggressive tires. These tires offer increased ground clearance at the axle, improved traction in various conditions, and greater resistance to punctures. Imagine a 4Runner with mud terrain tires, clawing its way through a muddy trail with ease, a stark contrast to its stock-tired counterpart struggling for grip.
-
Underbody Protection Enhancement
While not directly linked to the modification’s lift itself, the increased ground clearance it provides allows for the installation of robust underbody protection. Skid plates shield vulnerable components such as the oil pan, transfer case, and fuel tank from rocks and other hazards. Consider a 4Runner traversing a rocky trail, the skid plates deflecting potentially damaging impacts and safeguarding critical components.
These facets, each contributing to enhanced off-road capability, are intrinsically linked to the chassis elevation. It is this modification that unlocks the vehicle’s ability to traverse challenging terrain, transforming it from a capable SUV into a purpose-built off-road machine.
