Friction Material

Part Type:

GPZ Friction Clutch Pack Module with 3-5 Reverse Z Pak® and 4-5-6 Z Pak®

Friction Material Type:

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.
