The JSPEC121KFP pairs JKS long-arm control arms with Fox 2.0 Performance Series shocks and standard-rate coil springs. It's the most accessible Fox-equipped configuration in the J-Konnect 2.5\" standard-rate lineup — delivering proven geometry correction and reliable damping for stock-weight builds on moderate terrain.\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 compliance for stock-weight builds. Fox 2.0 Performance shocks deliver consistent, predictable damping for daily driving and moderate trail use. Adjustable upper and lower control arms allow precise alignment post-install. Axle wrap is eliminated and on-road composure is maintained at highway speeds.\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: Fox 2.0 Performance Series (non-reservoir)\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: JSPEC121KFP\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. For extended technical trail use, consider upgrading to the Fox 2.5 reservoir variant (JSPEC121PS) for improved heat management.\u003c\/p\u003e\n\n\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\n\u003cp\u003eOptimized for 35\" tires on a stock-weight build.

For half-day trail runs on moderate terrain, the 2.0 Performance holds up well. Where it starts to show its limits is on back-to-back technical days where heat cycles accumulate in the shock body. If your trail days run long or your terrain is aggressive, contact OFAS — we'll tell you whether the 2.5 reservoir is worth the step-up for your specific use case.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444652507457,"sku":"JSPEC121KFP","price":2315.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC121KFP_0-BKWD.jpg?v=1772726419","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec121kfp","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
