The JSPEC135KFP pairs JKS J-Kontrol control arms with Fox 2.0 Performance Series shocks and HD coil springs. HD coils handle the weight of a steel bumper or winch without sagging, and the Fox 2.0 Performance delivers consistent, predictable damping for moderate trail use and daily driving on the JL 2-Door platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3\" of lift with JKS J-Kontrol geometry correction.

Torque all control arm hardware to JKS specification after a 500-mile break-in. No cutting or welding required for standard JL 2-Door gas applications. For extended technical trail use with a heavy front end, consider upgrading to the Fox 2.5 Elite DSC variant (JSPEC135PES) for improved heat management and on-the-fly adjustment.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eEngineered for 35\"–37\" tires on an accessorized build. Recommended backspacing: 4.0\"–4.5\" on a 17\"×9\" or 17\"×8\" wheel. The JL 2-Door's shorter wheelbase makes fender clearance more sensitive to tire width at 3\" of lift — confirm tread width and brand 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 with HD coils on a J-Kontrol 3\" JL 2-Door build with a steel bumper and winch — how does the JL 2-Door's shorter wheelbase affect the 2.0 Performance's thermal ceiling compared to the same shock on a JL 4-Door with the same accessory load and coil rate at the same lift height? The JL 2-Door's shorter wheelbase produces faster chassis pitch cycles per trail obstacle, which means the 2.0 Performance is cycling more frequently per mile of trail than on the 4-Door. More cycles per mile means the 2.0 reaches its thermal ceiling faster on the 2-Door than on the 4-Door under the same accessory load. For moderate trail days on a lightly accessorized JL 2-Door, the 2.0 Performance is adequate. Add a full steel front end and run sustained rocky terrain and the thermal demand increases significantly. Contact OFAS with your build weight and trail profile and we'll confirm whether the Fox 2.5 Elite step-up is warranted.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444636582209,"sku":"JSPEC135KFP","price":2033.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC135KFP_0-BKWD.jpg?v=1772726182","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec135kfp","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
