JKS J-Venture 2.5" Lift Kit w/ Fox 2.0 Performance | 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 2.5" of lift with a short-arm system, Fox damping, and a coil rate tuned for maximum trail compliance — without the reservoir price premium or the complexity of a long-arm conversion. The JSPEC117KFP pairs JKS geometry-corrected short-arm control arms with Fox 2.0 Performance Series shocks and standard-rate coil springs. It's the most accessible Fox-equipped configuration in the J-Venture 2.5" standard-rate lineup.

The Result

2.5" of lift with JKS geometry-corrected short-arm control arms. Standard-rate coils maximize droop travel and trail articulation for stock-weight builds. Fox 2.0 Performance shocks deliver consistent, predictable damping for daily driving and moderate trail use. No differential drop required. Adjustable control arms allow precise alignment post-install.

Verified Fitment (OFAS Standard)

• Fits: 2018–2026 Jeep Wrangler JL 4-Door (Unlimited) — Gas Models, Stock-Weight Configuration
• Does NOT fit: JL 2-Door | JL Diesel (EcoDiesel) | JL 4xe Hybrid | JK (2007–2018) | Gladiator JT
• Coil Note: Standard-Rate — NOT recommended for builds with steel bumpers, winch, or heavy roof rack

System Specifications

• Lift Height: 2.5"
• System: J-Venture Short-Arm
• Shock: Fox 2.0 Performance Series (non-reservoir)
• Coil Rate: Standard-Rate — optimized for stock-weight JL 4-Door builds
• Control Arms: JKS geometry-corrected short-arm control arms
• SKU: JSPEC117KFP

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. No cutting or welding required for standard JL 4-Door gas applications. For extended technical trail use, consider upgrading to the Fox 2.5 reservoir variant (JSPEC117PS) for improved heat management.

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

Choosing the Fox 2.0 non-reservoir for a J-Venture 2.5" std-rate build on a stock-weight JL 4-Door — how does the 2.0 body handle the increased shock travel that standard-rate coils allow compared to HD coils at the same lift height? More droop travel means the shock cycles through a greater range of motion per obstacle, which increases heat accumulation over a trail day. For moderate terrain and half-day runs, the 2.0 Performance is well-suited. For longer, more aggressive days, contact OFAS — we'll tell you whether the Fox 2.5 reservoir is the right step-up for your specific trail profile.
