JKS J-Konnect 3.5" Lift Kit w/ J-Spec Shocks | 2018–2026 Jeep Wrangler JL 4-Door

Is This for You?

You want the full J-Konnect long-arm geometry upgrade on your JL 4-Door Unlimited but you're planning to run your own aftermarket shocks — or you're sourcing shocks separately to match a specific build spec. The JSPEC124K delivers the complete JKS long-arm control arm system with J-Spec monotube shocks as the included damper. It's the entry point into the J-Konnect platform without paying for a premium shock you may not need yet.

The Result

3.5" of lift with corrected long-arm caster and pinion geometry. J-Spec monotube shocks provide a baseline damping platform that outperforms factory units and serves as a functional starting point for future shock upgrades. Adjustable upper and lower control arms allow precise alignment post-install. Axle wrap is eliminated, flex is improved, and the JL's on-road composure is maintained at highway speeds.

System Specifications

  • Lift Height: 3.5"
  • System: J-Konnect Long-Arm
  • Shock: JKS J-Spec Monotube
  • Coil Rate: HD — tuned for 35"–37" tire loads
  • Control Arms: JKS adjustable upper and lower long-arm (front and rear)
  • SKU: JSPEC124K

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 period. No cutting or welding required for standard JL 4-Door gas applications. Confirm brake line and ABS sensor routing after lift is set.

Wheel & Tire Fitment

Engineered for 35"–37" tires. Recommended backspacing: 4.5"–4.75" on a 17"×9" or 18"×9" wheel. Confirm fender clearance with your specific tire brand and tread profile before finalizing wheel selection.

Engineering Question

Planning to swap the J-Spec shocks for Fox 2.5s or King 2.0s down the road on this J-Konnect 3.5" build? The long-arm geometry stays the same — but shock eye-to-eye length and mounting hardware compatibility varies by brand. Contact OFAS before you buy and we'll confirm drop-in fitment for your target shock upgrade.
