Heavy-duty vehicles, commercial vehicles, and high-stress driving enhanced performance applications GPZ680 features Made In USA GPZ friction material and is a replacement for the HL3Z-7B164-B 10R80, 10L80, 10L90 B Reverse (1-2-8-9-10) GPZ (10L80, 10L90 18-ON) Friction Clutch Plate.
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.
