3.5" 2007-2018 Jeep Wrangler JK (4 Door) J-Krawl Lift Kit by JKS

JSPEC193KFA JKS J-Krawl 3.5" Suspension System for 2007–2018 Jeep Wrangler JK 4-Door models is engineered for serious off-road enthusiasts who demand maximum articulation, strength, and full suspension adjustability. Designed as a complete bolt-on upgrade, this high-performance system transforms factory suspension geometry into a fully tunable setup capable of handling aggressive rock crawling, oversized tires, and demanding trail conditions while maintaining confident street manners.

At the core of the J-Krawl system are JSPEC dual-rate front and rear coil springs paired with your choice of premium FOX shock options, including FOX 2.0 Adventure Series, FOX 2.0 Performance Series, FOX 2.0 Remote Reservoir, and FOX 2.5 Performance Elite shocks. Each shock option is custom-valved to match the spring rates and overall system geometry, delivering controlled damping, improved stability, and predictable performance across technical terrain and daily driving alike.

Maximum adjustability comes from a full set of front and rear J-Flex upper and lower control arms, allowing precise tuning of caster, rear pinion angle, and overall wheelbase. Control arm options include high-articulation Flex End joints for superior misalignment capability or maintenance-free rubber bushings for reduced NVH and quieter operation. A front adjustable track bar and rear track bar bracket properly recenter the axles after lifting, while front sway bar Quicker Disconnects and bump stop extensions complete the system for improved articulation and component protection.

Built for Jeep owners who push their vehicles beyond mild trail use, the J-Krawl 3.5" Suspension System delivers the clearance, control, and durability required for hardcore off-road driving. An aftermarket front driveshaft is strongly recommended due to the additional suspension travel this system provides, ensuring long-term reliability under extreme use.
