Drive Flange Alum Chevy

The Drive Flange Aluminum Chevy by BERT TRANSMISSIONS is a precision crankshaft coupler engineered for high-performance Chevy V8 applications. This component serves as the critical interface between your engine's crankshaft and transmission, handling torque transfer while maintaining rotational balance. Whether you're building a street machine, bracket racer, or high-horsepower cruiser, the right drive flange is non-negotiable for reliable power delivery and transmission longevity.

Manufactured from durable aluminum, this 10-spline drive flange reduces rotating mass compared to heavier cast-iron alternatives, improving throttle response and engine efficiency. The aluminum construction also provides excellent strength-to-weight ratio without sacrificing durability under sustained load. At 0.62 lbs and compact dimensions of 4.8 x 1.4 x 4.95 inches, this flange is engineered for Bert Transmissions compatibility and delivers consistent engagement across repeated launch cycles. The 10-spline design ensures positive drive engagement with corresponding transmission input shafts, eliminating slippage and guaranteeing predictable power transfer during acceleration.

This drive flange is ideal for engine builders, transmission shops, and serious enthusiasts upgrading or rebuilding Chevy V8 drivetrains. It's particularly valuable when pairing Bert Transmissions with classic small-blocks or modern LS platforms that demand reliable torque coupling. Proper installation requires alignment with your engine's crankshaft nose and transmission input shaft spline, ensuring concentricity for vibration-free operation. Always verify compatibility with your specific Bert Transmission model and consult installation documentation before assembly.
