Hydraulic Clutch Actuation for your Classic Muscle Car, Hot Rod, or Race Car

For many enthusiasts, building a hot rod means it has to have three pedals and not two. A manual transmission is a MUST in their build. We certainly enjoy rowing through the gears ourselves and nothing makes that easier than a hydraulic clutch release bearing (or “throwout bearing” as some still call it). If you buy a new vehicle with a manual transmission today it will come with a hydraulic release bearing setup and that is for two primary reasons, pedal effort and packaging. These same two reasons are exactly why you should consider a Speedway Motors hydraulic release bearing kit for your manual transmission install. No longer do you have contemplate using bulky factory clutch release linkages that bind or take up valuable header and exhaust space and that require constant adjustment and maintenance, nor do you have to live with a heavy clutch pedal that has you reconsidering driving your pride and joy in any traffic. Using a hydraulic release bearing solves all these issues yet is easy to setup when installing your transmission.

Everything You Need in an Easy to Install Kit

Speedway Motors’ hydraulic release bearing kit provides everything you need to ditch your stock, tired mechanical linkage and go hydraulic at a great value. The kit features a new and improved release bearing designed by Speedway Motors’ Engineering Team with a CNC-machined housing, extended fluid line fittings, and a built-in fail-safe retainer. 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!). Also included are a sufficient number of release bearing shims to correctly set your air gap between the bearing face and clutch, as well as both 5/16- and ?-inch anti-rotation studs to fit a wide variety of GM manual transmission applications. This kit also features our braided bleeder line with adapter for outside the bellhousing clutch bleeding.

Fits a Wide Variety of Popular GM Transmissions

This hydraulic 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 when using a stock-style 10½- or 11-inch diaphragm clutch. Essentially any GM transmission with a 1?-inch OD bearing collar. The Speedway Motors hydraulic release bearing ships setup with AN -4 fluid line adapters along with a 12-inch bleeder line and a standard ¼-28 thread bleeder screw for easy external bleeding. Most applications will work exceptionally well with a ¾-inch bore master cylinder, such as Speedway Motors PN 91025680. Your hot rod may be a vintage time piece, but that does not mean your drivetrain has to be as well. Step into the 21st century with a Speedway Motors hydraulic clutch release bearing kit and your left calf muscle will thank you!
