The JSPEC138PES delivers JKS J-Kontrol control arms with Fox 2.5 Elite DSC reservoir shocks and HD coil springs. Driver-adjustable compression lets you compensate for the accessory load on the fly — firm it up for highway stability under a heavy steel front end, open it up for trail compliance. HD coils handle the weight of a steel bumper or winch without sagging. This is the highest-performing shock configuration in the J-Kontrol 2.5\" HD JL 4-Door lineup.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e2.5\" of lift with JKS J-Kontrol geometry correction. HD coils maintain ride height under accessory loads. Fox 2.5 Elite DSC shocks give you real-time compression adjustment to manage the accessory load's effect on front-end dynamics. Adjustable control arms allow precise alignment post-install. The J-Kontrol's install simplicity is a meaningful advantage on the JL 4-Door platform compared to a full long-arm conversion.\u003c\/p\u003e\n\n\u003ch3\u003eVerified Fitment (OFAS Standard)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e 2018–2026 Jeep Wrangler JL 4-Door (Unlimited) — Gas Models (2.0T, 3.6L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e JL 2-Door | JL EcoDiesel | JL 4xe Hybrid | JK (any year) | Gladiator JT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Note:\u003c\/strong\u003e HD Rate — engineered for accessorized JL 4-Door builds with steel bumpers or winch.

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.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Question\u003c\/h3\u003e\n\u003cblockquote\u003e\u003cp\u003eRunning Fox 2.5 Elite DSC with HD coils on a J-Kontrol 2.5\" JL 4-Door build with a steel bumper and winch — what DSC high-speed compression baseline should you start with to account for the accessory load's effect on front-end dynamics compared to a stock-weight JL 4-Door at the same lift height? A heavily loaded JL 4-Door generates higher peak shock velocities over sharp trail obstacles, which means the high-speed compression circuit needs more damping force to control body motion than on a stock-weight rig. Starting with the DSC set too soft for the accessory load will result in excessive nose dive on braking and front-end wallow on trail. Contact OFAS with your total front-end weight and primary terrain and we'll give you a DSC baseline starting position calibrated for your specific accessorized JL 4-Door J-Kontrol 2.5\" build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444633207105,"sku":"JSPEC138PES","price":4351.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC138PES_0-BKWD.jpg?v=1772726119","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec138pes","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
