The JSPEC137KFP pairs JKS J-Kontrol control arms with Fox 2.0 Performance Series shocks and standard-rate coil springs. Standard-rate coils maximize droop travel and trail compliance for stock-weight builds, and the Fox 2.0 Performance delivers consistent, predictable damping for moderate trail use and daily driving.\u003c\/p\u003e\n\n\u003ch3\u003eThe Result\u003c\/h3\u003e\n\u003cp\u003e2.5\" of lift with JKS J-Kontrol geometry correction.

Recommended backspacing: 4.5\"–4.75\" on a 17\"×9\" or 18\"×9\" wheel. At 2.5\" of lift, fender clearance with 35s is workable on a stock-weight rig — 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\u003eRunning Fox 2.0 non-reservoir shocks with standard-rate coils on a J-Kontrol 2.5\" stock-weight JL 4-Door — how does the combination of J-Kontrol geometry correction and standard-rate coils affect the 2.0 Performance's shock travel utilization compared to the same shock on a spacer lift with factory coils at the same ride height? The J-Kontrol's geometry correction allows more droop travel than a spacer lift, and standard-rate coils allow more droop than factory coils — both factors increase the shock's range of motion per obstacle. More travel range means the 2.0 Performance is working harder per trail mile than it would be on a spacer lift. For moderate trail days on a stock-weight JL 4-Door, the 2.0 Performance is adequate. Contact OFAS with your terrain profile and we'll confirm whether the Fox 2.5 Elite step-up is warranted for your specific build.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444635337025,"sku":"JSPEC137KFP","price":2033.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC137KFP_0-BKWD.jpg?v=1772726159","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec137kfp","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
