Product Description

The JKS JSPEC103KFA is a complete 2.5" J-Venture suspension lift system engineered specifically for the 2007-2018 Jeep Wrangler JK 2-Door. Every component is designed, tested, and assembled in the USA, then matched and tuned to work as a cohesive system for the 2-Door's unique wheelbase and weight distribution. Custom-wound JSPEC dual-rate coil springs deliver a composed, comfortable ride on the highway that firms up progressively under trail loads, while custom-valved FOX 2.0 Adventure Series IFP monotube shocks are tuned side-by-side those springs to maximize both on-road composure and off-road damping control.

A JKS front adjustable track bar and rear track bar relocation bracket keep the front axle properly centered at lifted height, while front caster cam locks restore correct steering geometry. JKS2034 Quicker Disconnect sway bar links disconnect in seconds at the trailhead for up to 30% more articulation, and brake line relocation brackets integrate with factory mounting tabs to eliminate the bracket rotation common with generic kits. At 2.5" of lift, the 2-Door JK can run up to 35x12.50 tires - a meaningful advantage over the same lift on the heavier 4-Door platform. Note: 2012-2018 models with the 3.6L Pentastar V6 require the JKS8150 exhaust extension kit for driveshaft clearance at full droop.
