Paired with Fox 2.5 Elite DSC reservoir shocks, the JSPEC109PES gives you driver-adjustable compression, superior heat dissipation, and a refined trail feel on the JK 2-Door platform.\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 2-Door's shorter wheelbase and lighter weight respond well to the J-Kontrol's geometry improvements at this lift height.\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. Confirm DSC adjuster knob placement for driver accessibility during install.

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\u003eDeciding between the J-Kontrol and J-Konnect at 3.5\" of lift for a JK 2-Door build with Fox 2.5 Elite DSC shocks — what's the practical geometry difference between the two systems on the JK platform? The J-Konnect's long-arm geometry delivers superior caster correction and articulation, but requires a differential drop and more complex install. The J-Kontrol corrects geometry without the long-arm conversion complexity. For a JK 2-Door that sees moderate trails and daily driving, the J-Kontrol is a capable, clean solution. Contact OFAS with your trail intensity and build goals and we'll confirm which system is the right fit for your JK 2-Door.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444665942337,"sku":"JSPEC109PES","price":4609.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC109PES_0-BKWD.jpg?v=1772726578","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec109pes","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
