The JSPEC108PES delivers JKS J-Kontrol control arms with Fox 2.5 Elite DSC reservoir shocks — driver-adjustable compression, superior heat dissipation, and a refined trail feel on the JK Unlimited platform without the complexity of a long-arm conversion.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS J-Kontrol geometry correction. Fox 2.5 Elite DSC shocks give you on-the-fly compression adjustment — open it up for trail compliance, firm it up for highway stability. Adjustable control arms allow precise alignment post-install. The JK 4-Door's longer wheelbase and heavier platform benefit from the DSC's ability to manage both slow-speed body pitch and high-speed impact harshness independently.\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 2007–2018 Jeep Wrangler JK 4-Door Unlimited (Sport, Sahara, Rubicon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e JK 2-Door | JL Wrangler (2018–2026) | Gladiator JT | Any JL variant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform Note:\u003c\/strong\u003e JK production ended 2018.

A heavily loaded JK 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. Contact OFAS with your total front-end weight and primary terrain type and we'll give you a DSC baseline starting position calibrated for your specific JK 4-Door Unlimited build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444667941185,"sku":"JSPEC108PES","price":4609.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC108PES_0-BKWD.jpg?v=1772726607","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec108pes","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
