From hardcore rock crawling to high-speed desert, the J-Krawl System brings a level of performance and adjustability that makes it the go to package for many Jeep enthusiasts. These systems build on the base systems and add comments for a full overhaul of the factory suspension to maximum articulation, strength and allow for adjustability.

This particular kit pulls out all the stops features the top of the line FOX 3.0 Factory Race Series IBP shocks. These race proven shocks have internal bypass technology along with DSC adjustment on the recirculating reservoirs to meet the extreme performance needs when charging offroad while to deliver next level performance with easy adjustment to dial in high-speed/low-speed compression damping for improved performance across off terrains. J-Krawl builds off Jeep’s factory suspension mounting points and upgrades everything front to rear. Adjustability is important for fine tuning suspension geometry. J-Krawl delivers. Dial in front caster, rear pinion and overall vehicle wheelbase. Take your Jeep's off-road performance and strength to the next level. It should be noted that an aftermarket front driveshaft is strongly recommended due to potential additional travel.
