Product Description

Raybestos® Powertrain GM 6L90 GPZ Clutch Pack® contains upgraded friction components manufactured with high-strength Stage-1 friction material for high temperature durability. for ultimate stress and high temperature durability. This kit also includes the 3-5 Reverse Z Pak® and 4-5-6 Z Pak® with GPZ friction material to provide solutions to common 6L90 transmission failure points. Z Paks are completely redesigned single-sided clutch systems that outperform OE in torque and heat capacity, without coning.

Recommended Use:

High-stress driving enhanced performance applications, heavy-duty vehicles, commercial vehicles, daily driven vehicles and as a problem solution for 3-5 Reverse and 4-5-6 clutch failure.

Friction Material Type:

Stage-1 frictions are not limited to performance, but also enhance heavy duty applications by increasing holding capacity, while being able to withstand higher temperatures associated with towing heavy loads. Raybestos Stage-1 Performance frictions are the best choice for street rods, tuner cars and mild street strip applications. Raybestos Powertrain GPZ friction plates greatly increase transmission performance and durability. This state-of-the-art friction material far exceeds OE material to withstand high stress, high temperatures and repeated cycling. GPZ's outstanding performance benefits are perfect for heavy-duty vehicles and high-stress driving. Testing of GPZ revolutionary friction material shows that it outperforms OE materials by as much as 20%. Plus, its performance improves as the power increases.
