Description

The Bert Gen 2 Standard Length Transmission Kit for 2-Piece Rear Main Seal is a lightweight, race-proven 2-speed direct-drive transmission package engineered for circle track racing, dirt modifieds, and limited-engine classes. Designed to bolt directly to Small Block Chevrolet (SBC) and Small Block Ford (SBF) engines with a 2-piece rear main seal, this kit delivers exceptional durability, quick acceleration, and reduced rotating mass for maximum power transfer to the rear wheels. The standard-length version matches the dimensions of a traditional Muncie transmission, making it a popular choice for race car conversions and replacements.

The revolutionary Bert Gen II transmission features an innovative internal design where first gear and reverse are completely disengaged while in direct drive (high gear). This significantly reduces rotating weight, minimizes internal wear, and improves throttle response and horsepower delivery. Rated for 600 lb-ft of torque, the aluminum-case transmission is built to withstand the demands of competitive racing while providing consistent and reliable performance on dirt or asphalt tracks.
