{"product_id":"gm-8-5-8-6-30-spline-steel-spool","title":"GM 8.5\" \/ 8.6\" 30 Spline Steel Spool","description":"The Yukon steel spool is a cost-effective component designed to convert a differential to 100% lockup. It installs directly in place of the differential carrier assembly.\n\nThis spool provides 100% traction to both wheels simultaneously, making it an ideal choice for dedicated off-road and drag racing applications. It is compatible with GM 8.5\" and 8.6\" axles featuring 30 spline axles and requires a gear ratio of 2.73 and up. Additionally, this product requires c\/clip eliminators for proper installation.\n\nPlease note that this spool is not recommended for street-driven vehicles due to its locked differential nature.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52871774765368,"sku":"YP FSGM8.5-30","price":498.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/gm-8-5-8-6-30-spline-steel-spool","provider":"MOTORMIA","version":"1.0","type":"link"}
