Description
Part #: JSPEC151KFA
Build the ultimate adventure rig with a 3.5" lift kit J-Krawl suspension system. Fits 4-Door Jeep Wrangler JK. Designed for maximum articulation and adjustability, the complete suspension system includes dual rate coil springs, adjustable front track bar, rear track bar bracket and tuned FOX shocks. The heart of the J-Krawl design is a set of J-Flex upper and lower control arms and sway bar Quicker disconnects. These systems build off Jeep's factory suspension mounting points and upgrades to front and rear, upper and lower J-Flex adjustable control arms for maximum articulation along with more strength for trails and rock crawling brawn along with adjustability to dial in front caster, rear pinion and overall vehicle wheelbase. In addition to eight high strength adjustable control arms, this J-Krawl system features specially designed FOX 2.0 Adventure Series IFP shocks to maximize travel and performance. An aftermarket front driveshaft is strongly recommended due to additional travel capable. Routine maintenance is required.
Features:
- Front/Rear Dual Rate Coil Springs designed for great ride quality and improved performance across any terrain
- Front/Rear FOX 2.0 Adventure Series IFP shocks specifically valved for this suspension system for improved performance on and off-road
- Front Adjustable Track Bar and Rear Track Bar Bracket to correct axle positioning under vehicle

- Front/Rear J-Flex Lower Control Arms for improved strength and caster correction
- Front/Rear J-Flex Upper Control Arms for improved strength and caster correction
- Front/Rear Bump Stop Extensions to properly limit suspension up travel.
