Your Circle Track Specialist!

Hightower 4-speed transmission







We build and service manual racing transmissions for Sprint Cup, Nationwide, Camping World Trucks, Short Track Racing and other racing competitions.  We specialize in light rotating weight 2-speed, 3-speed and 4-speed racing transmissions. Our customers are all over the United States, Canada, South Africa and Austrailia.  Transmissions can safely be shipped nationally and internationally inside a carefully designed shipping box (also available). 

At our facility in Travelers Rest, South Carolina, we are using sophisticated machine shop equipment and tooling to manufacture our transmission parts from raw steel.  We cut, shape and broach our own gears, input and output shafts, clusters and dog rings on sight.  We then deliver them to a heat treat facility for hardening.  Each part is designed to fit into our own case, creating a lighter weight, winning transmission.

Note:  Every transmission is custom built to your specifications.  Please call for delivery quotes.
