JKS J-Venture 3.5" Lift Kit w/ Fox 2.0 Performance | 2007–2018 Jeep Wrangler JK 2-Door

JKS J-Venture 3.5" Lift Kit w/ Fox 2.0 Performance | 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-Venture geometry correction and proven Fox damping at a value-forward price point. The JSPEC101KFP pairs JKS J-Venture control arms with Fox 2.0 Performance Series shocks — a significant upgrade over factory damping that delivers consistent, predictable performance for moderate trail use and daily driving on the JK 2-Door platform. No differential drop required, no fabrication, proven geometry correction.

The Result

3.5" of lift with JKS J-Venture geometry correction. Fox 2.0 Performance shocks deliver reliable, consistent damping for moderate trail use and daily driving. Adjustable control arms allow precise alignment post-install. The JK 2-Door's lighter weight and shorter wheelbase make it a well-matched platform for the 2.0 Performance's thermal capacity on moderate terrain.

Verified Fitment (OFAS Standard)

• Fits: 2007–2018 Jeep Wrangler JK 2-Door — Left-Hand Drive (LHD)
• Does NOT fit: JK 2-Door Right-Hand Drive (RHD) | JK 4-Door (any configuration) | JL Wrangler (2018–2026) | Gladiator JT
• Platform Note: JK production ended 2018. This kit does NOT apply to any 2019+ Wrangler.

System Specifications

• Lift Height: 3.5"
• System: J-Venture
• Shock: Fox 2.0 Performance Series (non-reservoir)
• Coil Rate: Tuned for JK 2-Door platform
• Control Arms: JKS J-Venture geometry-corrected control arms
• SKU: JSPEC101KFP

Installation & Fabrication Notes

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 JK 2-Door LHD applications. For extended technical trail use, consider upgrading to the Fox 2.5 Elite variant (JSPEC101PES) or Fox remote reservoir variant (JSPEC101KFR) for improved heat management.

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 at 3.5" of lift — confirm tread width and brand before finalizing wheel selection.

Engineering Question

Running Fox 2.0 non-reservoir shocks on a J-Venture 3.5" JK 2-Door build with 37" tires — how does the increased unsprung mass of 37" tires affect the 2.0 Performance's thermal load on a JK 2-Door compared to the same shock on a 35" tire setup? Larger tires increase unsprung mass, which increases the shock's peak velocity and force requirements over trail obstacles. On a lighter JK 2-Door, the 2.0 Performance handles 35" tires well on moderate terrain, but 37" tires push the thermal envelope faster. If you're committed to 37s, contact OFAS — we'll tell you whether the Fox 2.5 Elite or remote reservoir is the right step-up for your specific JK 2-Door build and terrain profile.
