Description

The Raybestos RGPZ-026 is a high-performance friction clutch pack module specifically engineered for the GM 6L80 automatic transmission, suitable for models from 2006 onwards. It utilizes Raybestos's proprietary GPZ friction material, known for its exceptional high-energy fiber blend, which offers superior durability and resistance to stress and high temperatures compared to OE materials. This advanced friction material is ideal for high-stress driving, enhanced performance applications, heavy-duty vehicles, commercial vehicles, and as a solution for common transmission failures. The included Z Pak® components, specifically the 3-5 Reverse Z Pak® and 4-5-6 Z Pak®, are re-engineered single-sided clutch systems that effectively outperform OE clutch systems in both torque and heat capacity without experiencing coning. The kit includes five GPZ565 1-2-3-4 clutches, five GPZ570 2-6 clutches, five GPZ580 Low/Reverse clutches, the RZP-005 3-5 Reverse Z Pak®, and the RZP-006 4-5-6 Z Pak®. It is intended for use with steel module part number 000615. Raybestos emphasizes that the GPZ friction material outperforms OE materials by as much as 20% and improves performance as power increases. The clutch pack's design aims to eliminate coning under high stress, increase transmission durability, and provide a perfect solution for every rebuild, including heavy-duty applications. The product is Made in the USA with GPZ material.
