The JSPEC122K delivers the complete J-Konnect 2.5\" HD system with JKS J-Spec monotube shocks and HD coil springs. It's the base-shock, heavy-duty coil configuration of the J-Konnect 2.5\" lineup for built rigs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e2.5\" of lift with long-arm caster and pinion correction. HD coils maintain ride height under steel bumper and winch loads. J-Spec monotube shocks provide a functional, predictable damping baseline that outperforms factory units and serves as a solid starting point for future shock upgrades. Adjustable control arms allow precise alignment post-install.\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-Konnect Long-Arm\u003c\/li\u003e\n\u003cli\u003eShock: JKS J-Spec Monotube\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 adjustable upper and lower long-arm (front and rear)\u003c\/li\u003e\n\u003cli\u003eSKU: JSPEC122K\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).

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\u003eEngineered for 35\" tires on an accessorized build. 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.\u003c\/p\u003e\n\n\u003ch3\u003eEngineering Question\u003c\/h3\u003e\n\u003cblockquote\u003e\u003cp\u003eStarting with J-Spec shocks on the J-Konnect 2.5\" HD platform and running a steel bumper plus winch — how long before the J-Spec shocks become the limiting factor on technical terrain? For moderate trails and daily driving, J-Spec monotubes hold up well. But if you're running sustained rocky terrain with a heavy front end, heat fade becomes a factor faster than on a reservoir shock. Contact OFAS with your trail profile and we'll tell you exactly when the Fox 2.5 upgrade makes sense for your specific build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444651163969,"sku":"JSPEC122K","price":1627.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC122K_0-BKWD.jpg?v=1772726397","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec122k","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
