{"product_id":"3-4-z-pak-clutch-pack-module-1","title":"3-4 Z Pak Clutch Pack Module","description":"The Raybestos Powertrain RZP-001 is a 3-4 Z Pak® Clutch Pack Module engineered for GM TH700-R4, 4L60E, 4L65E, and 4L70E transmissions manufactured from 1988 to the present. This performance-oriented module is specifically recommended for enhanced performance rebuilds where the original equipment (OE) clutch packs are known to fail under stress.\n\nIncluded in the RZP-001 are one 3-4 GPZ friction plate, one 3-4 apply plate, one 3-4 press plate, seven 3-4 SS OD spline GPZ plates, and seven 3-4 SS ID spline GPZ plates. An optional 3-4 OD spline shim is also provided. The Z Pak® system is patented and designed as a single-sided clutch system that excels in torque and heat capacity without coning, outperforming OE clutches under high stress conditions.\n\nThe GPZ friction material utilized in this clutch pack is state-of-the-art, exceeding OE standards. It is built to endure high stress, elevated temperatures, and repeated cycling, making it ideal for heavy-duty vehicles and demanding driving conditions. Testing indicates that GPZ friction material outperforms OE materials by as much as 20%, with its performance improving proportionally with increased power output. This material also significantly reduces maximum core temperatures, increases transmission durability, and boosts torque capacity.\n\nInstallation instructions are available for the 4L60E 3-4 Clutch ZPak, noting the requirement to use a 1988 or later input drum identified by a narrow snap ring groove and a 0.093” 3-4 snap ring. An apply ring measuring 3.675” ± 0.005” is also specified for use.","brand":"Z-pack","offers":[{"title":"Default Title","offer_id":52664170807608,"sku":"RZP-001","price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687545311.jpg?v=1784334621","url":"https:\/\/store.motormia.co\/products\/3-4-z-pak-clutch-pack-module-1","provider":"MOTORMIA","version":"1.0","type":"link"}
