The JSPEC113KFP pairs JKS long-arm control arms with Fox 2.0 Performance Series shocks — a significant upgrade over factory damping that delivers consistent, predictable performance for moderate trail use and daily driving on the JK Unlimited platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS long-arm caster and pinion correction. Fox 2.0 Performance shocks deliver reliable, consistent damping for moderate trail use and daily driving. Adjustable upper and lower control arms allow precise alignment post-install. Axle wrap is eliminated and the JK 4-Door's longer wheelbase delivers a composed, planted ride at highway speeds with this geometry correction in place.\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.

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 JK 4-Door applications. For extended technical trail use or heavily accessorized builds, consider upgrading to the Fox 2.5 Elite variant (JSPEC113PES) for improved heat management and DSC adjustment.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eEngineered for 35\"–37\" tires.

Confirm fender clearance with specific 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 2.0 non-reservoir shocks on a J-Konnect 3.5\" long-arm JK 4-Door Unlimited with a steel bumper and winch — how does the 4-Door's heavier curb weight and accessory load affect the 2.0 Performance's thermal ceiling compared to a stock-weight JK 2-Door at the same lift height? The 4-Door's additional mass increases the dynamic load per compression cycle, which reduces the 2.0's thermal headroom on sustained technical terrain. For moderate trail days on a lightly accessorized JK 4-Door, the 2.0 Performance is adequate. Add a full steel front end and the math changes. Contact OFAS with your build weight and trail profile and we'll confirm whether the Fox 2.5 Elite step-up is warranted for your specific JK 4-Door configuration.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444665581889,"sku":"JSPEC113KFP","price":2559.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC113KFP_0-BKWD.jpg?v=1772726571","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec113kfp","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
