From hardcore rock crawling to high-speed desert, the J-Krawl 2.5" Lift 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. Components include J-Flex upper and lower control arms, Jspec dual rate coil springs, an adjustable front track bar, a rear track bar bracket, quicker disconnect front sway bar end links, and bump stop extensions. This particular kit features next level performance from the FOX 3.0 Factory Race Series Internal Bypass shocks with DSC adjustment 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.
