Build the ultimate rock crawling Diesel 4-Door Jeep Wrangler JL with a J-Krawl 2.5" lift kit suspension system. The complete system is designed for maximum articulation, strength and adjustability. Components include J-Flex or J-Link Upper and Lower Control Arms, JSPEC dual rate coil springs, custom-valved shock options tailored to your needs, including FOX Adventure Series, FOX 2.0 Performance Series, FOX 2.5 Performance Series,FOX 2.5 Elite Series and FOX 3.0 Factory Race Series shocks, an adjustable front track bar, a rear track bar bracket, Quicker Disconnect front sway bar end links, and bump stop extensions. 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. The JKS Engineering team spent a lot of time dialing in the FOX shock valving and spring rates to suit J-Krawl's combination of parts as well as oversized wheels and tires. You'll be impressed with the stability and compression/rebound response. 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.
