Digressive, Linear, and Progressive Damping Curves
The behavior of a shock absorber is often described in terms of its damping curve, which illustrates the relationship between shock velocity and damping force. A digressive curve provides high damping force at low velocities, ideal for controlling body roll during cornering. A linear curve offers a consistent damping force across the velocity range, providing a balanced feel for both on- and off-road use. A progressive curve increases damping force with increasing velocity, offering a supple ride over small bumps while providing ample support for larger impacts. The choice of damping curve is crucial for achieving the desired handling characteristics.
-
The Interaction with Spring Rate
Damping characteristics and spring rate work in tandem to determine the overall suspension behavior. A stiffer spring requires more damping to prevent oscillations, while a softer spring requires less. Mismatched components can lead to undesirable results, such as a harsh ride or excessive body roll. A properly engineered coilover conversion kit will carefully match the spring rate to the damping characteristics of the shock absorber, ensuring a harmonious and predictable response.
Therefore, a 99-06 Silverado coilover conversion is not merely about achieving a certain ride height or aesthetic.

Factors such as the presence of aftermarket accessories (bumpers, winches) and the intended usage of the truck (daily driving, towing, off-roading) must also be considered. For instance, a Silverado frequently used for towing will necessitate a higher spring rate to maintain a level ride height and prevent excessive sag.
-
Linear vs. Progressive Springs
Coilover kits often offer a choice between linear and progressive springs. Linear springs provide a consistent spring rate throughout their compression, offering predictable and controlled handling. Progressive springs, on the other hand, feature a spring rate that increases with compression, providing a softer initial ride while offering greater resistance to bottoming out under heavy loads or during aggressive off-road maneuvers. A daily-driven Silverado might benefit from linear springs for their predictable handling, while a dedicated off-road rig might opt for progressive springs to absorb large impacts and maintain ground clearance.
-
The Interplay with Damping
Spring rate selection is inextricably linked to damping characteristics. The shock absorbers, responsible for controlling the spring’s motion, must be properly matched to the chosen spring rate. A spring rate that is too high for the available damping will result in a bouncy, uncontrolled ride, while a spring rate that is too low will allow the shocks to bottom out prematurely. Adjustable shock absorbers, often included in coilover conversion kits, offer a degree of fine-tuning to compensate for variations in spring rate and driving conditions.
