J-Max Jeep Suspension Systems - Lift Kits

JKS J-Rated J-Max Badge

If adjustability and maximum performance are what you are looking for, the J-Max delivers.

We start with the J-Krawl system that has 8 adjustable J-Flex control arms made out of 2” .250 wall DOM tubing, and we take it up a level by placing FOX 2.5” diameter, DSC adjustable Race series coil overs at all 4 corners. These coil overs are tuned to the specific model of Jeep they are installed on and deliver the ultimate in performance to the end user. Dual rate springs with tuneable crossover, Dual Speed Compression (DSC) adjustment to fine tune ride quality and ride height adjustment to fit your needs are just some of the benefits. The 2.5” diameter makes sure that fluid temps and strength of components is never an issue. A true bolt on system that while infinently tuneable, also will perform right out of the box with zero adjustments.
