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

Is This for You?

You already have quality shocks — Kings, Fox 2.5s, Bilstein 5100s — and you want the J-Konnect long-arm geometry upgrade on your accessorized JL 4-Door without paying for shocks you don't need. The JSPEC122KNS delivers the full J-Konnect 2.5" HD long-arm system with shock extension brackets, allowing you to retain and reuse your existing shock absorbers. HD coils handle the weight of a built rig. This is the bring-your-own-shocks configuration of the J-Konnect 2.5" HD lineup.

The Result

2.5" of lift with long-arm caster and pinion correction. HD coils maintain ride height under steel bumper and winch loads. Shock extension brackets adapt your existing shocks to the new lift geometry without requiring replacement. Adjustable upper and lower control arms allow precise alignment post-install. You get the full J-Konnect platform upgrade while protecting your existing shock investment.

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. Verify existing shock eye-to-eye length and body diameter compatibility with JKS extension brackets before install. No cutting or welding required for standard JL 4-Door gas applications.

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

Have a set of Fox 2.5 or King 2.0 OEM shocks you want to carry over into this J-Konnect 2.5" HD build? Shock extension compatibility depends on your shock's collapsed and extended length, not just the brand. Before you order JSPEC122KNS, send OFAS your shock model and current eye-to-eye measurement — we'll confirm whether the extension brackets in this kit give you the correct travel range at 2.5" of lift.
