TJM XGS coil springs are available in linear and progressive designs. They come in various heights and load carrying capacities enabling the optimum suspension system to be achieved. TJM XGS coil springs are manufactured on computer controlled coiling machines, scragged before and after shot peening, load tested and supplied in a durable powder coat finish.
Linear Coil Springs
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 vehicles equipped with accessories such as steel bull bars and winch combinations.
Progressive Coil Springs
Progressive rate coils provide a smooth and comfortable ride when the vehicle is unlade, 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. It’s an ideal solution for vehicles that carry weight periodically.
