Product Description

The JKS JSPEC100KFA is a complete 3.5" J-Venture suspension lift system for the 2007-2018 Jeep Wrangler JK Unlimited 4-Door. Every component in this bolt-on kit is engineered and assembled in the USA, then matched and tuned to work together as a unified system - not a collection of generic parts. Custom-wound JSPEC dual-rate coil springs deliver a plush ride at highway speeds that firms up predictably under off-road loads, while custom-valved FOX 2.0 Adventure Series IFP monotube shocks are tuned side-by-side the springs for immediate, fade-free damping control on and off the trail.

The system corrects suspension geometry at lifted height with a JKS front adjustable track bar, rear track bar relocation bracket, and front caster cam locks - delivering factory-like handling despite the additional lift. JKS2034 Quicker Disconnect sway bar links provide up to 30% more front axle articulation when disconnected at the trailhead, and proprietary brake line relocation brackets clip into factory mounting tabs to eliminate bracket rotation common with generic kits. Note: 2012-2018 models with the 3.6L Pentastar V6 require the JKS8150 exhaust extension kit for driveshaft clearance at full droop.
