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

Is This for You?

You're building a stock-weight JL 4-Door Unlimited and you want the top-spec Fox shock in the J-Venture 3.5" standard-rate lineup — without the complexity of a long-arm conversion. The JSPEC119PES delivers JKS short-arm geometry with Fox 2.5 Elite DSC reservoir shocks and standard-rate coil springs. Driver-adjustable compression lets you tune the ride between trail and highway without tools. This is the highest-performing shock option in the stock-weight J-Venture 3.5" configuration.

The Result

3.5" of lift with JKS geometry-corrected short-arm control arms. 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 maximum articulation on the trail, firm it up for highway stability. No differential drop required. The combination delivers a refined, responsive ride that outperforms any budget short-arm alternative at this lift height.

Installation & Fabrication Notes

Short-arm system does not require differential drop or relocation. 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. No cutting or welding required for standard JL 4-Door gas applications.

Wheel & Tire Fitment

Optimized for 35"–37" 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

Pairing Fox 2.5 Elite DSC with standard-rate coils on a J-Venture 3.5" short-arm build — does the DSC low-speed compression circuit give you meaningful adjustment range when the coil rate is already soft? Yes — but the interaction between low-speed DSC and std-rate springs is terrain-dependent. On slow, technical rock crawling, the low-speed circuit controls body roll and chassis pitch in ways the coil alone can't. Contact OFAS with your primary terrain type and we'll walk you through the optimal DSC starting position for your specific JL 4-Door build.
