JKS JSPEC138KNS J-Kontrol 2.5 Inch Lift Kit 4-Door with Shock Extension Brackets HD Rate Coils

The JKS J-Kontrol 2.5-inch lift kit is a comprehensive suspension system engineered specifically for 2018-2021 Jeep Wrangler JL 4-door models. This complete bolt-on system delivers enhanced ground clearance and off-road capability while maintaining exceptional on-road handling and daily driver comfort.

What Sets J-Kontrol Apart:

J-Kontrol takes the proven J-Venture foundation and adds front control arm correction brackets that flatten upper and lower control arm angles to correct caster geometry. This geometry correction significantly improves on-road handling by more closely mimicking factory suspension angles while accommodating the 2.5-inch lift height.

Complete Kit Includes:

• Front and rear custom wound dual-rate progressive coil springs (Heavy Duty rate for heavier loads)
• Front and rear shock extension/relocation brackets for proper shock mounting
• Front adjustable track bar and rear track bar bracket for correct axle positioning
• Front control arm correction brackets for improved geometry
• Front sway bar Quicker Disconnects and rear sway bar links for enhanced articulation
• Front and rear bump stop extensions to properly limit suspension travel
• Complete hardware package for installation

Heavy Duty Rate Coil Springs:

This kit features HD rate coil springs designed for vehicles equipped with aftermarket winch and bumper combinations or those carrying significant additional weight. The progressive rate design provides a plush ride during normal driving with increased spring rate as compression increases under load.

Shock Extension Brackets:

The included shock relocation brackets allow you to retain your factory shocks while achieving 2.5 inches of lift. These brackets are particularly useful for Rubicon models with stock FOX 2.5 shocks, though there may be a slight limitation in suspension down travel.

Performance:

The J-Kontrol system is ideal for daily driving, weekend trail use, and beach cruising. The matched component combination offers solid off-road performance without sacrificing the comfort needed for daily commuting. Rubicon models can accommodate up to 37x12.50 tires, while non-Rubicon models can fit 35x12.50 tires (17x9, 18x9, or 20x9 wheels with 5-inch backspacing recommended).
