Description
The Bert LMZ Transmission Kit for 1-Piece Rear Main Seal is a complete 2-speed racing transmission package designed specifically for 1986 and newer Chevrolet Small Block V8 engines equipped with a 1-piece rear main seal. Built around the proven Bert LMZ aluminum racing transmission, this kit is engineered to provide maximum horsepower transfer, lightning-fast shifting, and exceptional durability for dirt and asphalt circle track competition.
