03-13 RAM 2500/3500 DIESEL MULTI RATE FRONT COIL SPRINGS 6" LIFT

In our multi-rate springs, each coil is spaced differently, creating a variable spring rate. Initially, the springs compress easily for the first couple of inches. As more force is applied, the coils come closer together. In the bottom quarter of the spring, the coils eventually touch and become inactive, making the spring stiffer.

The more force applied, the more the spring rate increases. This design allows the springs to be compliant on small road bumps while maintaining control off-road, during hard braking, and in turns. These springs deliver high performance when driving aggressively while providing a smooth, comfortable ride the rest of the time.

For 2010 trucks, we’ve found that using a linear rate coil works best with the heavier 4th Generation vehicles, providing a supple, smooth ride while maintaining maximum performance.
