The JSPEC119K delivers the complete J-Venture 3.5\" standard-rate system with JKS J-Spec monotube shocks. It's the base-shock, trail-compliant configuration of the J-Venture 3.5\" lineup for stock-weight builds that want a clean short-arm install.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with JKS geometry-corrected short-arm control arms. Standard-rate coils maximize droop travel and trail articulation for stock-weight builds. J-Spec monotube shocks provide a functional, predictable damping baseline that outperforms factory units. No differential drop required. The platform is shock-upgrade-ready when you're ready to step up to Fox or King.\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, Stock-Weight Configuration\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\u003cli\u003e\n\u003cstrong\u003eCoil Note:\u003c\/strong\u003e Standard-Rate — NOT recommended for builds with steel bumpers, winch, or heavy roof rack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSystem Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLift Height: 3.5\"\u003c\/li\u003e\n\u003cli\u003eSystem: J-Venture Short-Arm\u003c\/li\u003e\n\u003cli\u003eShock: JKS J-Spec Monotube\u003c\/li\u003e\n\u003cli\u003eCoil Rate: Standard-Rate — optimized for stock-weight JL 4-Door builds\u003c\/li\u003e\n\u003cli\u003eControl Arms: JKS geometry-corrected short-arm control arms\u003c\/li\u003e\n\u003cli\u003eSKU: JSPEC119K\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.

Shock upgrade path (Fox 2.0, Fox 2.5, Fox 2.5 Elite) is compatible with this control arm platform — confirm eye-to-eye length with OFAS before purchasing replacement shocks.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eOptimized for 35\"–37\" tires on a stock-weight build.

For street-to-trail builds with moderate terrain, J-Spec shocks hold up well through multiple seasons. The inflection point is when you start running sustained technical terrain or add significant unsprung weight. Contact OFAS with your trail frequency and tire size and we'll give you an honest assessment of when the Fox upgrade makes sense for your specific use case.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444656275777,"sku":"JSPEC119K","price":1148.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC119K_0-BKWD.jpg?v=1772726473","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec119k","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
