Hughes Performance Competition Transmissions

Hughes Performance competition transmissions deliver exceptional strength and reliability under the most demanding conditions. In addition, these units are built using state-of-the-art performance components to ensure maximum durability. Each transmission is carefully inspected and assembled to precise tolerances, resulting in consistent quality and dependable operation.

Furthermore, these transmissions are equipped with reverse-pattern or, in some cases, forward-pattern valve bodies to provide firm, quick, and accurate shifts. As a result, drivers benefit from improved control and performance on the track. They also feature Hughes “Pro III” trans-brake valve bodies, which enhance launch consistency and overall race performance.

Most importantly, these transmissions are engineered to withstand repeated high-stress runs. Therefore, they are an excellent choice for racers who demand durability, precision, and long-lasting performance under extreme conditions.
