A Race Ready Clutch Kit That is Easy on your Budget

At Speedway Motors we love racing in all forms. From autocross and drag racing, to the sideways sliding, tire lifting madness that is oval track. We also know racing, on any track, can be expensive. Therefore, we work hard to manufacture parts for your racing program that last and keep money in your pocket. Our clutch kit is exactly what we are talking about.

Belhousing Built to Take the Abuse

We know that racing puts huge demands on your race car’s drivetrain. To that end we started with a laser-cut, CNC-finished engine block flange for a perfect fit to your small block Chevy engine. Using precise fixture welding the 7-gauge steel bell, along with the transmission mount flange (also laser-cut CNC-finished) are welded together to make a strong, long lasting part. This bellhousing is designed for the included hydraulic throwout bearing. At the bottom is a 6.3-inch opening 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 and Race Transmissions

Whether your ride has just been mildly modified or transformed into a real fire-breather, you need to consider Ace Manufacturing clutch and pressure plates. They are made in both fixed and adjustable static-pressure configurations, incorporating explosion-resistant plates made of steel or aluminum, plus features such as chrome-vanadium springs, heavy-duty covers, and high-strength hardware. This 10-1/2" racing clutch for GM applications is the perfect choice for Hobby or Street Stock racing.

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
  • Ace Manufacturing Lightweight 10-1/2" Pressure Plate
  • Ace Manufacturing Solid Organic 10-spline Clutch Disk
  • 153 Tooth Cast Iron Flywheel for 1 piece Main Small Block Chevy Engines
  • ARP Pressure Plate and Flywheel Bolts
  • Hydraulic Release Bearing Kit with anti-rotation studs, and air gap shims
  • Extra-Long Bronze Pilot Bushing
  • Clutch Alignment Tool
