Brinn Original Two Speed Transmissions

Brinn original transmissions prove not everything in racing needs to be complicated. With less weight and fewer parts, simplicity is their key to besting the competition. Their original 2-speed transmissions offer two power paths of success for your circle track racer. Direct drive and low gear move you forward unlike that of the competition and reverse is not meshed with any other gears while in either forward path--no robbed horsepower or reduced acceleration. And, there's less rotating weight to tax your engine when powering in and out of corners. Brinn's dog clutch and detent design of these original transmissions offer durability and the smoothest shifting without the need of special shifters. What's even simpler is the rebuild. No need for special tools. No need to remachine readily-available service parts. Available in aluminum or magnesium, there are no welded parts; all parts are billet or cast and precision CNC-machined. It's hard to beat a Brinn. Their original transmissions aren't complicated, just better.
