Linear or constant rate coils offer consistent spring rate in all situations. This coil spring design is suited to most 4WD vehicles to increase ride height and improve stability. They are ideally suited for installation to vehicle equipped with accessories such as steel bull bars and winch combinations.

Progressive Coil Spring

Progressive rate coil provide a smooth comfortable ride when the vehicle is unladen and improved stability and load carrying ability when the vehicle is loaded. Designed to increase the spring rate as the load increases, the vehicle displays less tendency to bottom out, thus improving ride comfort. Itís an ideal solution for vehicles that are laden only occasionally.
