Key Features:

  • 3.73:1 gear ratio optimized for balanced performance

  • Precision-manufactured using computer-controlled cutting with tolerances to 1/1000th of an inch
  • Special heat treatment process for enhanced strength and durability

Richmond Gear has been the choice of professional racers for over 80 years, with victories at the Daytona 500 and U.S. Nationals. Each gear set is manufactured using state-of-the-art processes from foundry to final heat treating, ensuring consistent quality and some of the strongest gears available. The 3.73 ratio provides excellent all-around performance for street-driven trucks and muscle cars, offering improved throttle response and acceleration while maintaining reasonable fuel economy on the highway.

Note: Professional installation is recommended. Requires proper setup tools, bearing kit, and installation kit (sold separately) for correct backlash and gear pattern setup.
