Description

Part #: JSPEC141K

Improve the ground clearance and off road capability of your 4 Door Jeep Wrangler JL with the JKS J-Kontrol 3.5" suspension system. The J-Kontrol system retains your OE control arms, but steps up the rest of your suspension. J-Kontrol kits feature dual rate coil springs, adjustable front track bar, specially-valved gas shocks, sway bar Quicker Disconnects, and front control arm correction brackets as well as all other necessary hardware for a complete bolt-on installation. 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.

Features:

  • Front/Rear Dual Rate Coil Springs designed for great ride quality across any terrain
  • Front/Rear JSPEC Gas Shocks 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

J-Kontrol: All the benefits of J-Venture along with geometry correcting brackets for enhanced on-road handling.
