The JSPEC123K is the base-shock, standard-rate coil configuration of the J-Konnect 3.5\" system — the most trail-compliant, budget-accessible version of this long-arm kit for lightly built Unlimiteds.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e3.5\" of lift with full long-arm caster and pinion correction. Standard-rate coils maximize droop travel and trail articulation for stock-weight builds. J-Spec monotube shocks deliver a functional, predictable damping baseline that outperforms factory units. Adjustable upper and lower control arms allow precise alignment dialing. The platform is shock-upgrade-ready when you're ready to step up.\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-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: JSPEC123K\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 J-Konnect control arm geometry stays the same — but shock body diameter, reservoir clearance, and eye-to-eye length all need to be verified against your specific JL 4-Door build before swapping. Contact OFAS with your target shock model and we'll confirm fitment and any bracket requirements before you pull the trigger.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444649427265,"sku":"JSPEC123K","price":1627.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC123K_0-BKWD.jpg?v=1772726368","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec123k","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
