Manual Transmission Fans Rejoice 

There’s nothing cooler than a muscle car or street rod with three pedals, and we’re making the installation easier all the time with parts like our steel bellhousing, Speedway Motors’ hydraulic throwout bearing kits, and everything else you need to mate your transmission to your engine and keep your project moving forward. So, whether it is a classic four-speed or a modern five-speed you are installing behind that domestic V-8 engine, we have the parts you need!

Belhousing Built to Take the Abuse

When we designed this steel bellhousing, we wanted it to directly replace the original cast piece with a precision part. To that end we started with laser-cut a36 3/8-inch thick steel to make the CNC-finished engine block flange for a perfect fit to your small or big block Chevy engine. Using precise fixture welding the 7-gauge steel bell is welded to the engine block flange along with the transmission mount flange (also laser-cut CNC-finished from 1/2-inch thick a36 steel) to make a strong, long lasting part. This bellhousing is designed for included hydraulic throwout bearing, and we have provided a 1-inch hole at the top and driver’s side for hydraulic feed and bleeder line routing. At the bottom is a 6.3-inch opening with a bolt-on cover to allow quick clutch and throwout bearing inspections. The bellhousing is protected from the elements with a black zinc plated coating and is made right here in the USA. 

Heavy Duty Clutch for Stock Transmissions

These clutch kits feature a pressure plate with over 1700 lbs of clamping force, which makes for a stronger, more agressive clutch but retains the stock pedal feel. The clutch disc is unique in that it uses a double spring which is held in place by a unique spring retaining plate design. This 10-1/2" clutch for GM applications is the perfect choice for mild engine street bruiser.

Hydraulic Clutch Actuation

Speedway Motors’ hydraulic release bearing 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 3/8-inch anti-rotation studs to fit a wide variety of GM manual transmission applications.

Kit includes:

  • Steel Bellhousing Laser-Cut, CNC-finished flanges for perfect fit, Non SFI rated
  • Street Series 10.4 Inch Clutch Kit, 1-1/8 inch - 10-spline
  • 153 Tooth Speedmaster Billet Flywheel
  • ARP Pressure Plate and Flywheel Bolts
  • Hydraulic Release Bearing Kit with anti-rotation studs, and air gap shims
  • Bellhousing Bolts
