Brinn Aluminum Transmission 70001

For circle track racers who demand reliability without compromise, the Brinn Aluminum Transmission 70001 delivers lightweight performance with internal hydraulic actuation that eliminates external clutch assemblies entirely. The cryogenically treated shafts and gears combined with a superior dog clutch design mean you'll get consistent, smooth shifts lap after lap while shedding unnecessary rotating weight. IMCA-approved for Stock Car, Modified, and Late Model competition, this bolt-in unit replaces factory GM transmissions with minimal fabrication required.
