Speedway Chevy Clutch Hydraulic Release Throwout Bearing Kit

Easy Hydraulic Clutch Actuation for Your Race Car

Prepping your race car for the weekend race is a lot easier when you have a solid drivetrain putting your engine’s power to the ground. You’ve saved up and you are finally ready to step up your program with a great multi-disc racing clutch, a new bellhousing, and a strong transmission to ensure you make it through the season without issue. It is time to ditch that old mechanical clutch linkage too and all of its associated maintenance and adjustments as well. Keep that forward momentum going by using a solid hydraulic throwout bearing that will not put you on the trailer, ending your race weekend early! Speedway Motors’ new throwout bearing is CNC-machined from billet aluminum for light weight and superior strength and is the perfect pairing with your new driveline components to put you in the winner’s circle!

Everything You Need in an Easy to Install Kit

Speedway Motors’ hydraulic throwout bearing kit provides everything you need to outfit your racing drivetrain with a hydraulic throwout bearing at a great value. The kit features a new and improved throwout bearing designed by Speedway Motors’ Engineering Team with a CNC-machined housing, and both 5/16- and 3/8-inch mounting studs with adjuster nuts to fit a wide variety of GM manual transmission applications to correctly set your air gap between the bearing face and clutch. The built-in fail-safe retainer prevents separation of the bearing due to over extension. There is simply no way to over-extend this release bearing with this retainer design. Typically over-extending the release bearing means pulling the transmission and reassembling the separated bearing (not to mention cleaning up all that hydraulic fluid in the bellhousing!) and potentially damaging the internal seals.  The kit also includes the hydraulic throwout bearing bolt kit, fittings and the AN line to connect the throwout bearing to the hydraulic clutch master cylinder. 

Fits a Wide Variety of Popular GM and Racing Transmissions

This hydraulic throwout bearing kit will fit most Chevrolet, BOP, and GMC manual three- and four-speed transmissions, such as the Muncie family of four-speeds, Borg Warner T10 and Super T10 four-speeds, Saginaw three- and four-speeds, and even the GM-spec Tremec TKO-500 and 600 five-speeds. Essentially any GM transmission with a 1-3/8-inch OD bearing collar. If you are running a Jerico 2-speed or 4-speed transmission, or the Richmond 4-speed or 5-speed transmission in your race car this bearing will work for you as well. The Speedway Motors hydraulic release bearing ships setup with AN -4 fluid line adapters and a standard 1/4-28 thread bleeder screw for in bellhousing bleeding. This can be upgraded easily to an external bleeder setup using Speedway Motors AN hose and fitting kit, PN 91025603. Most applications will work exceptionally well with a 3/4-inch bore master cylinder, such as Speedway Motors PN 91025680.
