The JSPEC109KFR delivers JKS J-Kontrol geometry-corrected control arms with Fox remote reservoir shocks — the remote canister separates the oil and nitrogen charge from the shock body, dramatically improving heat dissipation on sustained technical terrain. If your JK 2-Door sees long, aggressive trail days and you want the J-Kontrol's install simplicity with remote reservoir performance, this is your kit.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS J-Kontrol geometry correction. Fox remote reservoir shocks maintain consistent damping performance across extended trail runs where body-mounted reservoir shocks begin to fade. Adjustable control arms allow precise alignment post-install. The JK 2-Door's lighter weight and shorter wheelbase make it an ideal platform for the remote reservoir's performance advantages on technical terrain.\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 2-Door (Sport, Sahara, Rubicon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e JK 4-Door (Unlimited) | 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.

Torque all control arm hardware to JKS specification after a 500-mile break-in. Remote reservoir canister routing must be planned during install — confirm clearance against frame, skid plates, and body panels before finalizing mount locations. The J-Kontrol system does not require a differential drop, which simplifies canister routing compared to a long-arm conversion. No cutting or welding required for standard JK 2-Door applications.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eEngineered for 35\"–37\" tires. Recommended backspacing: 4.5\"–4.75\" on a 17\"×9\" or 18\"×9\" wheel. The JK 2-Door's shorter wheelbase makes fender clearance more sensitive to tire width — confirm tread width and brand before finalizing wheel selection.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Question\u003c\/h3\u003e\n\u003cblockquote\u003e\u003cp\u003eChoosing between the J-Kontrol with Fox remote reservoir versus the J-Konnect long-arm with Fox remote reservoir on a JK 2-Door — if the shock spec is identical, where does the real-world performance difference show up on trail? The difference is entirely in the control arm geometry. The J-Konnect's long-arm delivers superior caster correction and articulation at 3.5\" of lift; the J-Kontrol gets you geometry improvement without the differential drop and long-arm complexity. If your JK 2-Door is a serious trail rig that sees sustained technical terrain, the J-Konnect long-arm is the better long-term platform. Contact OFAS with your build goals and we'll confirm which system is the right call for your specific JK 2-Door use case.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444666270017,"sku":"JSPEC109KFR","price":2809.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC109KFR_0-BKWD.jpg?v=1772726584","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec109kfr","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
