JKS J-Kontrol 3.5" Lift Kit w/ Fox 2.5 Elite | 2007–2018 Jeep Wrangler JK 2-Door

JKS J-Kontrol 3.5" Lift Kit w/ Fox 2.5 Elite | 2007–2018 Jeep Wrangler JK 2-Door

Is This for You?

You're building a JK 2-Door and you want 3.5" of lift with the J-Kontrol system — JKS's geometry-corrected control arm platform that delivers improved caster and pinion angle without the full long-arm conversion complexity of the J-Konnect. Paired with Fox 2.5 Elite DSC reservoir shocks, the JSPEC109PES gives you driver-adjustable compression, superior heat dissipation, and a refined trail feel on the JK 2-Door platform.

The Result

3.5" of lift with JKS J-Kontrol geometry correction. Fox 2.5 Elite DSC shocks give you on-the-fly compression adjustment — open it up for trail compliance, firm it up for highway stability. Adjustable control arms allow precise alignment post-install. The JK 2-Door's shorter wheelbase and lighter weight respond well to the J-Kontrol's geometry improvements at this lift height.

Installation & Fabrication Notes

Professional 4-wheel alignment required post-installation. Torque all control arm hardware to JKS specification after a 500-mile break-in. Confirm DSC adjuster knob placement for driver accessibility during install. Verify Fox 2.5 reservoir clearance against skid plates and body panels. No cutting or welding required for standard JK 2-Door applications.

Wheel & Tire Fitment

Engineered for 35"–37" tires. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. The JK 2-Door's shorter wheelbase makes fender clearance more sensitive to tire width — confirm tread width and brand before finalizing wheel selection.

Engineering Question

Deciding between the J-Kontrol and J-Konnect at 3.5" of lift for a JK 2-Door build with Fox 2.5 Elite DSC shocks — what's the practical geometry difference between the two systems on the JK platform? The J-Konnect's long-arm geometry delivers superior caster correction and articulation, but requires a differential drop and more complex install. The J-Kontrol corrects geometry without the long-arm conversion complexity. For a JK 2-Door that sees moderate trails and daily driving, the J-Kontrol is a capable, clean solution. Contact OFAS with your trail intensity and build goals and we'll confirm which system is the right fit for your JK 2-Door.
