These components are aftermarket parts designed for specific General Motors vehicles produced from 1978 to 1988, primarily those built on the “G-body” platform. They replace the factory-installed suspension links that connect the rear axle to the vehicle’s chassis. The key feature is their adjustability, allowing for modifications to the rear suspension geometry. As an illustration, altering the length of these links can influence pinion angle and instant center, which are crucial for optimizing traction and handling.
The implementation of these adjustable parts offers several advantages over the stock components. Notably, they permit fine-tuning of the suspension to suit various driving conditions, such as drag racing or street performance. This adjustability is particularly beneficial for vehicles that have undergone modifications like lowering, which can negatively impact suspension geometry and necessitate correction to maintain optimal handling and prevent premature wear. Their presence represents a significant evolution in suspension technology for this vehicle platform, offering improvements in performance and control not available in the original design.
