The JSPEC121K delivers the complete J-Konnect 2.5\" standard-rate system with JKS J-Spec monotube shocks. It's the base-shock, trail-compliant configuration of the J-Konnect 2.5\" lineup for stock-weight builds.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e2.5\" of lift with long-arm caster and pinion correction. 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. Adjustable control arms allow precise alignment post-install. 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: 2.5\"\u003c\/li\u003e\n\u003cli\u003eSystem: J-Konnect Long-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 adjustable upper and lower long-arm (front and rear)\u003c\/li\u003e\n\u003cli\u003eSKU: JSPEC121K\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\n\u003cp\u003eLong-arm geometry requires a front differential drop or relocation bracket (included or specified in kit). Professional 4-wheel alignment required post-installation. Torque all control arm hardware to JKS specification after a 500-mile break-in. No cutting or welding required for standard JL 4-Door gas applications. 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\" tires on a stock-weight build.

The long-arm control arm geometry is identical across all shock variants in this lineup — but the std-rate coil's travel range means your replacement shock needs to match a specific eye-to-eye length to avoid binding at full droop. Contact OFAS before you buy your upgrade shocks and we'll spec the exact fitment for your JL 4-Door build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444652900673,"sku":"JSPEC121K","price":1627.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC121K_0-BKWD.jpg?v=1772726425","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec121k","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
