Alum Transmission 2nd Generation 22in OAL

The Alum Transmission 2nd Generation 22in OAL from BERT TRANSMISSIONS is a purpose-built gearbox engineered for high-performance automotive applications where weight reduction and compact packaging are critical priorities. This aluminum transmission serves drag racing, street rod, and custom vehicle builders who demand a bulletproof drivetrain without the weight penalty of cast-iron alternatives. At 45 lbs, this unit delivers significant chassis balance and acceleration improvements compared to conventional transmissions, making it the choice for serious enthusiasts building competition or show-quality vehicles.

BERT's second-generation aluminum design maximizes durability while minimizing rotating mass—a critical factor in quarter-mile performance and launch characteristics. The 22-inch overall length (OAL) provides optimal tunnel fit in mid-mounted or rear-engine configurations, allowing builders to optimize weight distribution without sacrificing driveline geometry. Aluminum construction reduces unsprung weight, improves suspension compliance, and lowers the center of gravity, translating to measurable gains in acceleration, handling response, and braking performance. The compact footprint and lightweight profile make this transmission ideal for vehicles running tight engine bays or requiring precise weight targeting for class regulations.

This transmission excels in dedicated race cars, tube-frame dragsters, and purpose-built hot rods where every pound counts and reliability cannot be compromised. Mechanics and fabricators specify BERT transmissions for consistency and proven track record across bracket racing, street racing, and amateur motorsports. Installation requires proper driveshaft phasing, tunnel clearance verification, and appropriate engine-to-transmission adapter selection based on your specific powerplant. Consultation with BERT's technical support or an experienced transmission shop ensures correct fitment and optimal performance for your build.
