Bert Gen 2 Std Length Transmission Kit for 1 Piece Rear Main Seal

The Bert Gen 2 Standard Length Transmission Kit for 1-Piece Rear Main Seal is a complete racing transmission package designed specifically for 1986-up Small Block Chevrolet engines equipped with a 1-piece rear main seal. Engineered for dirt track, oval track, and circle track competition, this kit combines the proven Bert Gen II Standard Length transmission with the essential components required for a dependable, race-ready drivetrain.

The Bert Gen II transmission is renowned for its innovative low rotating mass design. In direct drive (high gear), the first and reverse gear assemblies are completely disengaged, reducing internal drag and allowing more engine power to reach the rear wheels. This results in improved throttle response, greater drivetrain efficiency, and exceptional durability under demanding racing conditions.

Constructed with a lightweight, high-strength aluminum case, the Bert Gen II Standard Length transmission is engineered to handle up to 600 lb-ft of torque while delivering consistent performance throughout long race events. The included heavy-duty steel bellhousing is compatible with both Small Block Chevrolet (SBC) and Small Block Ford (SBF) engine bolt patterns and adapts to Muncie and Saginaw transmission mounting patterns commonly used in competitive racing.

Designed exclusively for race vehicles, this transmission kit is ideal for IMCA Modifieds, Wissota Modifieds, Midwest Modifieds, Sport Mods, Hobby Stocks, Dirt Modifieds, and other circle track racing classes where lightweight construction and maximum drivetrain efficiency are essential.
