53-Series 7.25” Driveline Packages feature a family of match components to offer the highest level of performance and reliability. Designed for applications that require an OEM size bellhousing, front (engine) mount starter, 153-tooth flywheel and a 7.25” clutch.
These packages offer additional ground clearance when compared to full size bellhousings that are designed for 168-tooth flywheels, allowing the engine to be mount lower in the chassis.
Typical Applications
- Road Racing
- Drifting
- Stock Car
- Vintage
53-Series 7.25” driveline packages include:
Bellhousing
- Rigid aluminum bellhousing resists flexing, allowing maximum power to be transferred to the wheels and minimizes wear to driveline components
- Integral “ears” with flanged inserts can be used as a rear engine mount and connect directly into the chassis
- Blueprinted for parallelism and concentricity
- Designed for use with any transmission with a tradition GM bolt pattern
Clutch-Flywheel-Assembly
- 7.25” OT-II 3-plate or 4-plate metallic clutch provides race proven performance and reliability
- Clutch disc to fit 1 5/32” X 26 (1 1/8” X 26) spline input shafts
- Billet steel 153-tooth flywheel
- Aircraft grade hardware
Hydraulic Release Bearing
- Bellhousing mounted HRB enable the transmission removed without effecting release bearing set-up
- High temperature quad tensioner mono-seal ensures a leak-resistant seal
- High quality 44mm contact diameter bearing maximizes clutch modulation and provides reliable operation
- Superior materials and proprietary low friction coatings provide longevity and consistency
Super Starter
- 40000-Series (3.0HP) gear-reduction Super Starter
