JKS J-Krawl 3.5" Lift Kit - 4 Door

Build the ultimate adventure rig with a 3.5" lift kit J-Krawl suspension system. Fits 4-Door Jeep Wrangler JL. 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 shock absorbers. 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 or J-Link 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, the J-Krawl system features specially designed 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 to maximize travel and performance. An aftermarket front driveshaft is strongly recommended due to additional travel capable. Routine maintenance is required.

Picking the Right Coil Springs

JKS J-Rated Suspension Systems feature custom-wound, progressive rate coil springs. That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising, with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight.

Flex Ends

Forged flex end and jam nut Flex end design allow for 30-degrees of misalignment (15 in either direction) for impressive articulation and are greaseable to ensure long bushing life. Completely rebuildable and serviceable on the trail with our JKS Flex Joint tools (link to tool).

Rubber Bushings

Engineered specifically to reduce NVH characteristics (Noise, Vibration, Harshness), these factory-style maintenance-free rubber bushings come pre-installed at both ends and will ensure a quiet, controlled ride with hassle-free operation in any environment.
