The JSPEC117KNS delivers the full J-Venture 2.5\" standard-rate system with shock extension brackets, allowing you to retain and reuse your existing shock absorbers. Standard-rate coils maximize trail compliance for stock-weight builds. This is the bring-your-own-shocks configuration of the J-Venture 2.5\" std-rate lineup.\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.

Standard-rate coils allow more droop than HD coils, which means the shock needs a longer extended length to avoid topping out at full droop. A shock that works fine at stock ride height may run out of travel at 2.5\" with std-rate springs. Send OFAS your shock model and current eye-to-eye measurement before ordering and we'll confirm whether the extension brackets give you the correct travel range.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444663124289,"sku":"JSPEC117KNS","price":1129.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC117KNS_0-BKWD.jpg?v=1772726518","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec117kns","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
