JKS J-Konnect 2.5" Lift Kit w/ Fox 2.0 Performance | HD Coils | 2018–2026 Jeep Wrangler JL 4-Door

Is This for You?

You're running a moderately accessorized JL 4-Door Unlimited — steel bumper, winch, or heavy spare — and you want the J-Konnect long-arm geometry upgrade at a value-forward price point. The JSPEC122KFP pairs JKS long-arm control arms with Fox 2.0 Performance Series shocks and HD coil springs. It's the most accessible Fox-equipped configuration in the J-Konnect 2.5" HD lineup, delivering proven geometry correction and reliable damping without the cost of a reservoir shock.

The Result

2.5" of lift with long-arm caster and pinion correction. HD coils maintain ride height under accessory loads. Fox 2.0 Performance shocks deliver consistent, predictable damping for moderate trail use and daily driving. Adjustable upper and lower control arms allow precise alignment post-install. Axle wrap is eliminated and on-road composure is maintained at highway speeds.

• SKU: JSPEC122KFP

Installation & Fabrication Notes

Long-arm geometry requires a front differential drop or relocation bracket (included or specified in kit). 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. If planning extended technical trail use, consider upgrading to the Fox 2.5 reservoir variant (JSPEC122PS) for improved heat management.

Wheel & Tire Fitment

Engineered for 35" tires on an accessorized build. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. At 2.5" of lift, fender clearance with 35s is tight — confirm tire brand and tread width before finalizing wheel selection.

Engineering Question

Choosing between the Fox 2.0 non-reservoir and Fox 2.5 reservoir for your J-Konnect 2.5" HD build on an accessorized JL 4-Door? The 2.0 Performance handles moderate trail days and daily driving without issue — but if you're running sustained rocky terrain with a heavy front end, the 2.5 reservoir's heat dissipation becomes a real advantage. Tell OFAS your typical trail length and front-end weight and we'll help you decide which shock is the right call for your build.
