{"product_id":"3-4-z-pak-clutch-pack-module","title":"3-4 Z Pak Clutch Pack Module","description":"The Raybestos Powertrain GM 4L60E 3-4 Z Pak® Clutch Pack Module (RZP-001) is engineered to solve common issues with OE clutch packs in high-performance and heavy-duty applications. This module is specifically designed for 1988-on GM TH700-R4, 4L60E, 4L65E, and 4L70E transmissions.\n\nUtilizing Raybestos Powertrain's GPZ Extreme Duty Paper friction material, this clutch pack significantly increases transmission performance and durability. The advanced friction material is built to withstand high stress, extreme temperatures, and repeated cycling, making it ideal for heavy-duty vehicles and demanding driving conditions. Testing indicates that GPZ material outperforms OE materials by as much as 20% and improves performance as power output increases.\n\nThe Z Pak® design is patented and features a single-sided clutch system that outperforms OE in both torque and heat capacity, while also preventing 'coning' under high stress. This can lead to reduced maximum core temperatures, increased torque capacity, and enhanced transmission durability. For new OEM platforms, the Z Pak design can allow for a smaller, lighter clutch assembly with greater thermal capacity. On existing designs, it increases torque capacity and reduces core temperatures, leading to a significant reduction in hot spotting and extended clutch life.\n\nKey components included in the RZP-001 are 1 3-4 GPZ friction plate, 1 3-4 Apply Plate, 1 3-4 Press Plate, 7 3-4 SS OD Spline GPZ plates, 7 3-4 SS ID Spline GPZ plates, and an optional 1 3-4 OD Spline Shim. Note that the Seal 18G701 for the transmission filter is sold separately for 2005-on models.","brand":"Raybestos Powertrain","offers":[{"title":"Default Title","offer_id":52663441162552,"sku":"RZP-001","price":134.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687610973.jpg?v=1784326927","url":"https:\/\/store.motormia.co\/products\/3-4-z-pak-clutch-pack-module","provider":"MOTORMIA","version":"1.0","type":"link"}
