The JSPEC118PS delivers JKS geometry-corrected short-arm control arms with Fox 2.5 Performance Series reservoir shocks and HD coil springs. It's the premium-shock, heavy-duty coil configuration of the J-Venture 2.5\" lineup for built rigs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e2.5\" of lift with JKS geometry-corrected short-arm control arms. HD coils maintain ride height under accessory loads. Fox 2.5 reservoir shocks deliver consistent damping and heat dissipation on extended trail runs. No differential drop required. Adjustable control arms allow precise alignment post-install. The result is a capable, planted JL 4-Door that handles the weight of a built rig without sacrificing on-road composure.\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 2018–2026 Jeep Wrangler JL 4-Door (Unlimited) — Gas Models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes NOT fit:\u003c\/strong\u003e JL 2-Door | JL Diesel (EcoDiesel) | JL 4xe Hybrid | JK (2007–2018) | Gladiator JT\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSystem Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLift Height: 2.5\"\u003c\/li\u003e\n\u003cli\u003eSystem: J-Venture Short-Arm\u003c\/li\u003e\n\u003cli\u003eShock: Fox 2.5 Performance Series w\/ Reservoir\u003c\/li\u003e\n\u003cli\u003eCoil Rate: HD — tuned for accessorized JL 4-Door builds with steel bumpers or winch\u003c\/li\u003e\n\u003cli\u003eControl Arms: JKS geometry-corrected short-arm control arms\u003c\/li\u003e\n\u003cli\u003eSKU: JSPEC118PS\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\n\u003cp\u003eShort-arm system does not require differential drop or relocation.

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\u003eRunning a J-Venture 2.5\" HD short-arm build with Fox 2.5 reservoir shocks on a JL 4-Door with a full steel front end — how does the Fox 2.5 reservoir's heat capacity compare to the 2.0 non-reservoir under sustained trail use with a heavy front end? The reservoir adds meaningful thermal capacity — but the real variable is your trail length and terrain type. A 3-hour rocky trail with a loaded front bumper will stress any shock differently than a 1-hour moderate run. Contact OFAS with your build weight and trail profile and we'll confirm whether the 2.5 reservoir is the right spec for your use case.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444657914177,"sku":"JSPEC118PS","price":1912.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC118PS_0-BKWD.jpg?v=1772726478","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec118ps","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
