Features:
Complete Kit: The hydraulic throwout bearing kit is compatible with most Chevrolet, BOP (Buick, Oldsmobile, Pontiac), and GMC manual 3- and 4-speed transmissions.
High Compatibility: It fits Muncie 4-speeds, Borg Warner T10 and Super T10 4-speeds, Saginaw 3- and 4-speeds, and GM-spec Tremec TKO-500 and 600 5-speeds when using a stock-style 10.5—or 11-inch diaphragm clutch.
Built To Last: The hydraulic throwout bearing kit is made of heavy-duty steel and every part is carefully selected & tested to provide great reliability in function, performance, and quality.
Superior Performance: This hydraulic throwout bearing delivers lower pedal effort compared to stock-type mechanical clutch linkages, thanks to its advanced hydraulic design.
Good As New: Upgrading your GM transmission to hydraulic clutch release will make installing the clutch and transmission easier. Not only eliminates the need for factory clutch release linkages that typically bind and take up header/exhaust space but also removes the need for adjustment, and maintenance and helps improve the pedal feel.

The 910-25610 hydraulic throwout bearing is typically used with:
GM stock-style diaphragm clutches (10.5" or 11")
Small Block Chevy (SBC) V8 engines
Manual 3- and 4-speed GM transmissions, including:
Muncie 4-speed
Borg Warner T10 and Super T10
Saginaw 3- and 4-speeds
Tremec TKO-500 and TKO-600 5-speeds (with GM input shaft)
Vehicles like classic muscle cars, hot rods, and race cars
It's designed for use with stock-style pressure plates and works well behind thicker aftermarket clutch setups due to its compact design.
