The extension bracket compatibility depends on your shock's collapsed length and eye-to-eye measurement at ride height — not just the brand. A shock that fits perfectly at 2\" of lift may bind or bottom out at 2.5\" with std-rate coils if the travel range isn't matched correctly. Send OFAS your shock model and current measurements before ordering and we'll confirm drop-in fitment.\u003c\/p\u003e\u003c\/blockquote\u003e","brand":"JKS Manufacturing","offers":[{"title":"Default Title","offer_id":51444652147009,"sku":"JSPEC121KNS","price":1567.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/1284\/1793\/files\/JSPEC121KNS_0-BKWD.jpg?v=1772726414","url":"https:\/\/obsidianforgedautosupply.com\/products\/jks-jspec121kns","provider":"Obsidian Forged Auto Supply","version":"1.0","type":"link"}
