Bert Dirt Modified Aluminum Transmission (GEN 2) with Shifter 78-SG SG-1200(78-SG)

Weight is everything in dirt modified racing, and this second-generation Bert transmission delivers a decisive advantage. At just 32.2 pounds with 50% less rotating mass than the original MOZ unit, you'll feel the difference in acceleration, handling response, and fuel efficiency. The internal hydraulic clutch and optimized engagement ratio mean faster shifts and more consistent power delivery when it matters most—and it bolts directly into your existing driveshaft setup with zero modifications required.
