Suncoast 10R80 F Clutch Expanded Capacity Module

Upgrade the Weak Link in Your 10R80 Transmission

The Suncoast 10R80 F Clutch Expanded Capacity Module is engineered to address one of the most common failure points in the 10R80 transmission. Designed as a direct drop-in replacement, this upgraded clutch pack significantly improves durability and performance without requiring any machining.

Built for High Load & Performance Applications

The factory “F” clutch is heavily utilized throughout the gear range, engaging in Reverse, 4th, 5th, 6th, 7th, 8th, and 9th gears. Under high load conditions—especially wide open throttle shifts from 3rd to 4th—this clutch is prone to premature wear, particularly in tuned vehicles with reduced torque management.

25% Increased Clutch Capacity

Suncoast solves this issue by increasing clutch capacity by 25%, upgrading the pack from 4 clutches to 5 clutches. This added surface area improves holding power, reduces slippage, and enhances overall transmission reliability under demanding conditions.

Developed with Industry-Leading Technology

Through an active partnership with Raybestos Powertrain, Suncoast has developed one of the most advanced solutions available for the 10R80 platform. Extensive real-world testing and R&D ensure this module performs under both street and high-performance use.

Why Upgrade the F Clutch?
