JKS J-Kontrol 3.5" Lift Kit w/ Fox 2.5 Elite DSC | Standard-Rate Coils | 2018–2026 Jeep Wrangler JL 4-Door

Is This for You?

You're running a stock-weight JL 4-Door Unlimited and you want the top-spec Fox shock in the J-Kontrol 3.5" standard-rate lineup. The JSPEC141PES delivers JKS J-Kontrol control arms with Fox 2.5 Elite DSC reservoir shocks and standard-rate coil springs. Driver-adjustable compression lets you dial in the shock for trail compliance or highway stability, while the standard-rate coils maximize droop travel and articulation for stock-weight builds. This is the highest-performing shock configuration in the J-Kontrol 3.5" standard-rate JL 4-Door lineup.

The Result

3.5" of lift with JKS J-Kontrol geometry correction. Standard-rate coils maximize droop travel and trail compliance for stock-weight builds. 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.

Verified Fitment (OFAS Standard)

• Fits: 2018–2026 Jeep Wrangler JL 4-Door (Unlimited) — Gas Models (2.0T, 3.6L), Stock-Weight Configuration
• Does NOT fit: JL 2-Door | JL EcoDiesel | JL 4xe Hybrid | JK (any year) | Gladiator JT
• Coil Note: Standard-Rate — NOT recommended for builds with steel bumpers, winch, or heavy roof rack. Use JSPEC142PES (HD coils) for accessorized builds.

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 JL 4-Door gas applications.

Wheel & Tire Fitment

Optimized for 35" tires on a stock-weight build. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. Standard-rate coils are not recommended for tire sizes exceeding 37" without load confirmation from OFAS.

Engineering Question

Running Fox 2.5 Elite DSC with standard-rate coils on a J-Kontrol 3.5" stock-weight JL 4-Door — does the J-Kontrol's geometry correction change the DSC low-speed compression baseline compared to a J-Konnect long-arm at the same lift height and coil rate on the same stock-weight JL 4-Door? Yes — the J-Kontrol and J-Konnect use different control arm travel arcs, which produces different chassis pitch dynamics under the same terrain conditions. The DSC low-speed baseline that works on a J-Konnect may not be optimal on a J-Kontrol at the same lift height and coil rate. Contact OFAS with your terrain type and we'll give you a DSC starting position calibrated specifically for the J-Kontrol's geometry on a stock-weight JL 4-Door at 3.5" of lift.
