Description
This suspension system was developed for the most extreme off-road terrain. The long travel race kit is capable of 17.5” of travel and can accept up to a 37” tire. We have perfected the suspension geometry by relocating the upper control arm mounts and modifying the outer pivot locations on the spindle. With these changes we were able to achieve twice the amount of travel compared to stock and eliminate bump steer throughout the suspension cycle. The kit accepts 2.5 x 10” coil overs, 3.0 x 10” bypasses, and 2.0 X 2.0 bump stops for superior suspension dampening. This kit is constructed using parts commonly found on trophy trucks such as massive Probearing 1.5" uniballs and JMX series heims. The result is a suspension system with reliable performance and off road handling that will exceed all expectations. This kit must be installed by a qualified off road shop.

Wheel Travel
When shopping long travel kits many consumers tend to focus just on travel numbers. This is the reason many companies claim inaccurate numbers or don’t disclose the amount of work involved to achieve those numbers. Our suspension systems are built to allow for maximum wheel travel, perfected suspension geometry, and an overall product with a simplified installation process and is easily serviceable. We disclose as much information as possible so you can make an educated purchase and won’t be left with any surprises.
Tire Info
When using 37” tires with this kit modifications to the wheel well will need to be made. The firewall pinch weld will need to be folded over to avoid contact while turning. The upper wheel well will also need to be modified to avoid contact at full bump.
