JKS JSPEC167KNS 3.5" J-Kontrol Suspension Lift Kit with JSPEC Shocks Standard Rate Coils

The JKS JSPEC167KNS is a 3.5" J-Kontrol suspension lift kit engineered for the Jeep Wrangler JL 4-Door. As a true bolt-on system, the J-Kontrol builds on the J-Venture platform by adding front control arm correction brackets, delivering exceptional handling and stability for both daily driving and demanding off-road use.

This kit includes JSPEC custom-valved steel monotube gas shocks specifically tuned to complement the included dual-rate coil springs for a balanced, controlled ride in any condition. The front and rear JSPEC dual-rate coil springs use a progressive rate design — plush during highway cruising and firmer as compression increases under load or off-road, delivering a ride quality that improves on the factory setup.

Key Features:

• 3.5" of lift for increased ground clearance and larger tire fitment
• Front and rear JSPEC dual-rate coil springs — standard rate — for smooth on- and off-road performance
• Custom-valved JSPEC gas shocks specifically tuned for this suspension system
• Front adjustable track bar and rear track bar bracket to correct axle centering under the vehicle
• Front control arm correction brackets that work with factory control arms to flatten geometry and correct caster
• Quicker-Disconnect sway bar end links for improved articulation off-road and solid on-road handling
• Front and rear bump stop extensions to protect drivetrain components at full compression
• All necessary hardware included for a complete bolt-on installation
• Built in the USA with a limited lifetime warranty against manufacturer defects in materials and workmanship

The J-Kontrol system retains your Jeep's stock control arms while correcting suspension geometry angles for improved caster and on-road handling. Whether you're commuting, beach cruising, or tackling regular trail use, the JSPEC167KNS provides the performance and comfort to match any adventure.
