Professional 4-wheel alignment required post-installation. Torque all control arm hardware to JKS specification after a 500-mile break-in. Verify existing shock eye-to-eye length and body diameter compatibility with JKS extension brackets before install. No cutting or welding required for standard JL 4-Door gas applications.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eEngineered for 35\" tires on an accessorized build. Recommended backspacing: 4.5\"–4.75\" on a 17\"×9\" or 18\"×9\" wheel. At 2.5\" of lift, fender clearance with 35s is tight — confirm tire brand and tread width before finalizing wheel selection. 37\" tires are not recommended at this lift height without fender modification.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Question\u003c\/h3\u003e\n\u003cblockquote\u003e\u003cp\u003eCarrying over a set of Fox 2.5 Performance or Bilstein 5100 shocks into this J-Venture 2.5\" HD short-arm build on an accessorized JL 4-Door — will the extension brackets maintain correct shock travel at full droop under HD coil load? The extension bracket geometry is designed for specific collapsed and extended shock lengths. A shock that clears at stock ride height may bind or over-extend at 2.5\" with HD coils if the travel range isn't matched. Send OFAS your shock model, current eye-to-eye measurement, and front-end accessory weight before ordering — we'll confirm drop-in fitment before the kit ships.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444660896065,"sku":"JSPEC118KNS","price":1087.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC118KNS_0-BKWD.jpg?v=1772726489","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec118kns","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
