Increase the clearance and performance of your 4-Door Jeep Wrangler JL with a 2.5" lift J-Kontrol™ suspension system. It delivers exceptional stability on and off road. A step up from JKS J-Venture™ systems, J-Kontrol™ is a true bolt-on system that adds in front control arm correction brackets to the J-Venture Kit's long list of upgrade components including JSPEC dual-rate coil springs, custom-valved FOX 2.5 Performance Elite Series shocks equipped with Dual Speed Compression adjusters, a front adjustable Track Bar and rear Track Bar Bracket (to correct axle positioning under vehicle), Quicker-Disconnect sway bar end links, front/rear Bump Stop Extensions and front Control Arm Correction Brackets to flatten upper/lower control arm angles. The supplied control arm brackets work with your Jeep's stock control arms to correct caster and improve handling. J-Kontrol offers enhanced performance for daily driving, beach cruising, or regular trail use.
FOX’s all-new Performance Elite shocks are a game changer for Jeep enthusiasts. PN 883-26-050 2.5” diameter remote reservoir monotube shocks are designed specifically for Wrangler JLs with 2-3” Lift - front position. Valving is tuned specifically for JLs with larger than stock aftermarket wheels and tires. Get ready to take your driving experience to a whole new level. External reservoirs provide increased oil and nitrogen capacity for fade-free operation plus hardcore appearance. Dial-in performance to match your personal driving style and Jeep’s specs with FOX Dual Speed Compression (DSC) adjusters. You’ll get improved ride quality and handling on road, with exceptional damping control and reliability off-road. 2.5" impact extruded and CNC machined 6061-T6 aluminum bodies are hard anodized to resist corrosion and weigh less than steel body shocks. End treatments and other components are black-anodized aluminum for striking contrast. Inside, extreme-duty hard-chromed, heat treated 7/8" steel shafts drive race-developed high-flow pistons and proprietary seals. Travel (in): 11.170” | Compressed Length (in): 17.340” | Extended length (in): 28.510” | Top Mount: Eyelet | Bottom Mount: Eyelet | Sold in pairs.
