3.5" 2007-2018 Jeep Wrangler JK (2 Door) J-Krawl Lift Kit by JKS

JSPEC152KFA JKS J-Krawl 3.5" Suspension System is engineered for 2007–2018 Jeep Wrangler JK 2-Door models seeking maximum articulation, strength, and suspension adjustability. Designed as a complete high-performance upgrade, this system transforms the factory suspension into a fully tunable platform capable of handling aggressive rock crawling while maintaining confident on-road manners.

At the core of the J-Krawl system are front and rear adjustable J-Flex or J-Link upper and lower control arms, allowing precise adjustment of caster, pinion angle, and overall wheelbase. Constructed from heavy-wall DOM tubing, these control arms significantly increase strength over factory components while offering two bushing options to tailor performance. Choose maintenance-free rubber bushings for reduced NVH and street comfort, or opt for high-articulation Flex End joints for maximum trail performance and serviceability.

JSPEC dual-rate coil springs provide a controlled, comfortable ride on pavement and transition to a firmer rate during off-road compression for improved stability and traction. The system includes a selection of custom-valved FOX shock options — 2.0 Adventure Series, 2.0 Performance Series, 2.0 Remote Reservoir, and 2.5 Performance Elite — each tuned to complement the spring rates and geometry for balanced performance across a wide range of terrain.

An adjustable front track bar and rear track bar bracket properly recenter the axles after lifting, while front sway bar Quicker Disconnects increase articulation when the trail demands it. Front and rear bump stop extensions protect shocks and suspension components at full compression. For extreme off-road use, an aftermarket front driveshaft is strongly recommended due to the increased suspension travel. The J-Krawl 3.5" system delivers serious trail capability with the strength, adjustability, and control required for demanding builds.
