Improve the ground clearance and off road capability of your Diesel 4 Door Jeep Wrangler JL with the JKS J-Kontrol 2.5" lift kit. The J-Kontrol lift retains your OE control arms, but steps up the rest of your suspension. J-Kontrol kits feature Diesel specific dual rate coil springs, adjustable front track bars specially-valved gas shocks, sway bar Quicker Disconnects, and front control arm correction brackets as well as all other hardware to complete the 2.5" lift. The J-Kontrol 2.5" lift suspension kit is the perfect daily driver, weekend wheeler system. J-Kontrol system's front control arm correction brackets further enhance the on-road handling by flattening out the control arm to more closely mimic factory angles while correcting caster. With a matched combination of parts, J-Kontrol systems offer very solid performance without compromising daily-driver comfort. If you spend a good amount of time on the trails, take control with J-Kontrol.


  • Front/Rear Dual Rate Coil Springs designed for the Diesel to provide great ride quality across any terrain.
  • Front/Rear Gas Shocks (Jspec, FOX 2.0 Performance Series) specifically valved for this suspension system for improved performance on and off-road.
  • Front Adjustable Track Bar and Rear Track Bar Bracket to correct axle positioning under vehicle.
  • Front Sway Bar Quicker Disconnects and Rear Sway Bar Links for increased offroad articulation.
  • Front/Rear Bump Stop Extensions to properly limit suspension up travel.
  • Front Control Arm Correction Brackets to flatten upper/lower control arm angles to correct caster and improve handling.
