Turn your Wrangler JL into a serious off-road rig with a JKS J-Krawl lift kit. 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, the J-Krawl system features specially designed FOX shocks to maximize travel and performance. An aftermarket front driveshaft is strongly recommended due to additional travel capable. Routine maintenance is required.
If you’re building the ultimate Jeep Wrangler JL, install FOX Factory Race Series 3.0 Internal Bypass shocks. PN 883-26-057 front position shocks deliver race-dominating, extreme-duty performance on all terrains. Designed for bolt-on installation on Jeep Wrangler JLs with JKS 2-3” lift kits, the remote reservoirs feature connect via hose to new recirculating bridges. Separate high and low-speed compression adjustments help you fine tune performance to your exact driving style and vehicle specs. The remote reservoirs feature finned bodies to help dissipate heat and maintain optimal fluid temps. Inside the shock bodies, position-sensitive internal bypass technology provides a plush, predictable ride during normal off-road driving conditions with the ability to ramp up damping force to counteract harsh bottom-outs or top-outs. Additional features include large 3” diameter hard-anodized, aluminum-bodies 7/8” shafts, race-bred pistons and valving, PTFE-lined spherical bearings, proprietary racing oil and high-temp Viton® seals. You won’t find a more capable off-road shock for your Jeep Wrangler JL. On road, expect a firm ride quality compared to JKS JSPEC, FOX Performance 2.0 and FOX Performance Elite shocks. Travel (in): 11.870” | Compressed Length (in): 18.925” | Extended length (in): 28.715” | Top Mount: Eyelet | Bottom Mount: Eyelet | Sold in pairs.
