{"product_id":"gm-12-bolt-30-spline-spider-gear-set","title":"GM 12-Bolt 30-Spline Spider Gear Set","description":"This specific kit is designed as a direct replacement for the spider gear set within Yukon Dura Grip and Eaton limited-slip differential positraction units.\n\nThe kit contains essential components for a complete spider gear replacement: two side gears, two pinion gears, a cross pin shaft, a roll pin, and spider gear thrust washers. Please note that this kit does not include clutches. It is designed to fit GM 12T and 12P differentials that are already outfitted with a Dura Grip or Eaton positraction unit and feature 30-spline axles.\n\nImportant fitment considerations apply: this kit ONLY fits the current Eaton style Posi, which has springs and plates located between both side gears. It is NOT compatible with the early GM version Posi that utilized long, skinny springs and spring plates under the side gears, between the side gear and clutches, as this earlier version is obsolete. Furthermore, this kit DOES NOT FIT factory limited-slip differentials.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52871778042168,"sku":"YPKGM12-P-30","price":391.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/gm-12-bolt-30-spline-spider-gear-set","provider":"MOTORMIA","version":"1.0","type":"link"}
