This set of 4 RockJock coil springs will provide 3 1/2 inches of lift in Jeep JT Gladiators that feature the diesel engine. These springs directly replaces the factory coil springs and are designed to work with RockJock Johnny Joint suspension systems or other manufacturer's 3 to 5-inch lift kits.

This spring set, besides lifting the vehicle 3.5 inch, also levels the vehicle and provides an improved ride. Extensive research was done by RockJock to develop the perfect combination of rates and quality of the coil springs.
