The JSPEC109K delivers the complete J-Kontrol 3.5\" system with JKS J-Spec monotube shocks. It's the base-shock configuration of the J-Kontrol 3.5\" JK 2-Door lineup — proven geometry correction, functional damping, and a clear upgrade path when you're ready to step up to Fox.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS J-Kontrol geometry correction. J-Spec monotube shocks provide a functional, predictable damping baseline that outperforms factory units. Adjustable control arms allow precise alignment post-install. The JK 2-Door's lighter weight and shorter wheelbase make it a forgiving platform for J-Spec shocks on moderate terrain. The platform is shock-upgrade-ready when you're ready to step up.\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.

Shock upgrade path (Fox 2.0 Adventure, Fox 2.0 Performance, Fox 2.5 Elite) is compatible with this control arm platform — confirm eye-to-eye length with OFAS before purchasing replacement shocks.\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\u003eStarting with J-Spec shocks on the J-Kontrol 3.5\" JK 2-Door platform and planning a Fox 2.0 Adventure or Fox 2.5 Elite upgrade after your first trail season — does the J-Kontrol's control arm geometry impose any unique shock eye-to-eye length requirements compared to the J-Konnect long-arm at the same lift height on the JK 2-Door? Yes — the J-Kontrol and J-Konnect use different control arm travel arcs, which means the correct shock eye-to-eye length for an upgrade shock must be verified against the J-Kontrol's specific geometry, not the J-Konnect spec. Contact OFAS with your target shock model before you buy and we'll confirm the exact fitment spec for your JK 2-Door J-Kontrol build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444667777345,"sku":"JSPEC109K","price":1399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC109K.png?v=1773586815","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec109k","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
