Raybestos Frictions & Steels
Raybestos Powertrain GPZ friction clutch 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%.
Raybestos Powertrain steel clutch plates are high quality, application-engineered products at a price you can afford. Manufactured with attention to critical tolerances and quality control, our steel plates meet or exceed OE specifications and have a superior surface finish that supplies a greater apply area and friction clutch life. Raybestos steel plates give better shift performance and clutch durability, lowering noise and shudder, extending the life of your transmission.

The Expanded Capacity E Drum
- 29% more clutch capacity than OEM
- Billet apply piston diameter enlarged to avoid "clutch cone" by contacting more surface area of top steel
- Billet 6061 apply piston ensures minimal deflection
- Patent-pending design made in-house in Florida
- 15% more capacity than any other aftermarket drum
- Steels engage on 4140 steel dowels, instead of the problematic cast aluminum drum assembly
SunCoast's Category 3 Rebuild Kit also comes with our 10L1000 High capacity "E" clutch drum with billet apply piston. This new High Capacity 10L1000 clutch drum arrives fully assembled for effortless installation. Our high-capacity 10L1000 "E" clutch drum addresses all of the facets affecting the durability of these clutches in highly demanding driving situations.
To improve clutch life we first started by simply increasing the clutch count. This new 10L1000 clutch drum boasts an astounding 29% increase in clutch capacity compared to the factory drum, surpassing any other aftermarket option on the market today by an additional 15%.
Another key point we address here is the deflection in the E-clutch. This is especially exacerbated when operating under higher line pressures, often experienced during heavy-duty or higher-load situations.
The new SunCoast 10L1000 "patent-pending" E-piston is engineered to eliminate any possibility of apply-deflection or coning. By using superior materials and increasing the apply piston diameter, we have significantly expanded the contact surface area. Crafted from billet T6061 aluminum bar stock and meticulously CNC machined in-house to exact tolerances, this new "E" Drum Apply Piston for the 10L1000 embodies SunCoast's excellence in design.
Moreover, we've tackled the issue of rapid drum degradation caused by steel tooth chatter/engagement. SunCoast's solution involves the designing of specialty 4140 steel dowels for the steels to engage with, replacing the highly malleable factory-cast aluminum. This design allows us to ensure reliability while keeping reciprocating mass at a minimum.
The friction material was also addressed as we have changed from the factory friction material which is engineered and designed to provide maximum "NVH" for comfort. This new 10L1000 drum is equipped with Raybestos GPZ clutches.
