JKS JSPEC135KFA 3.5 Inch J-Kontrol Lift Kit FOX Adventure Shocks Heavy Duty Coils 2 Door Jeep Wrangler JL

The JKS JSPEC135KFA J-Kontrol suspension system delivers a 3.5-inch lift for 2-Door Jeep Wrangler JL models, providing exceptional stability and performance both on and off road. This complete bolt-on system builds upon the J-Venture platform by adding front control arm correction brackets to the comprehensive upgrade package that includes JSPEC heavy-duty dual-rate coil springs, custom-valved FOX 2.0 Adventure Series IFP gas shocks, adjustable front track bar, rear track bar bracket, Quicker-Disconnect sway bar end links, and bump stop extensions.

Control Arm Correction Technology:

The supplied control arm correction brackets work with your Jeep's stock control arms to correct caster, flatten upper and lower control arm angles, and significantly improve on-road handling characteristics while maintaining factory-like geometry. These bolt-on brackets lower the frame side mounting point of the front control arms, effectively giving your Jeep the smooth handling of a long arm kit.

FOX 2.0 Adventure Series Shocks:

This kit features FOX 2.0 Adventure Series IFP steel-bodied shocks offering a significant upgrade from OE shocks for improved performance on and off-road. Built with FOX's proven 2.0-inch shock body and internal floating piston (IFP) design, these shocks deliver consistent damping and fade-free performance. The internal IFP mono-tube reservoir design separates shock oil from high-pressure nitrogen to prevent oil aeration.

Heavy-Duty Dual-Rate Coil Springs:

This kit is based on JKS's proven J-Venture system and features front and rear dual-rate coil springs for superior consistency and handling. The JSPEC135KFA model includes heavy-duty rate coils specifically engineered for 2-door Wrangler JL applications, providing enhanced load-carrying capacity for vehicles equipped with heavier bumpers, winches, and armor.
