The Rubicon Express spring-over axle conversion suspension system is designed for the truly adventurous off-roader, and is a fabricator’s delight. This suspension system moves the leaf spring perches to the topside of the axle. The result is a net lift height increase of 5.5” with stock height springs. The use of stock spec springs will maintain the factory ride quality while the spring-over configuration will greatly increase the suspension flexibility, allowing room for larger tires and vastly improve the visual appeal of your Jeep. The Spring-Over conversion requires welding new perches to the top of the axle. Steering modifications are required and a SYE/CV-driveshaft is mandatory. If you desire even more lift, the addition of a set of Rubicon Express Extreme-Duty Spring Over leaf springs (RE1444 and RE1445) result in a total lift height of 7 inches. The spring-over axle suspension configuration will allow the use of 33” tires when using stock leaf springs. The fitment of even larger tires is possible with additional modifications.
