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, United Kingdom, 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 steel, aluminum and magnesium.  We cut, shape and broach our own gears, input and output shafts, clusters, dog rings and other parts on sight.  Our cases are poured at the foundry using our own pattern and shipped to our facility where we machine them as needed.  Each part is designed to creat a strong, lighter weight, winning transmission.
