Product Details

The Richmond Gear 79-0080-1 Pro Gear Ring and Pinion Set is engineered specifically for drag racing applications where hard launches and severe heat cycling occur. This race-only gear set features a 4.57:1 ratio (32 ring teeth, 7 pinion teeth) designed for Ford 9-inch differentials with a 35-spline big pinion configuration.

Key Features:

  • 9310 steel alloy construction—softer and more malleable to resist breakage under harsh racing conditions
  • Lightweight design offers up to 6 pounds of rotating weight reduction for improved performance
  • 1.513-inch pinion shaft diameter with 35-spline count for enhanced strength
  • 9-inch ring gear diameter with 10 bolt holes for secure mounting
  • Ground pinion threads to gage quality for trouble-free installation
  • Special heat treatment for improved strength and durability
  • Requires special 35-spline pinion support (not included)

Richmond Gear has been the leading manufacturer of professional-quality, high-performance ring and pinion sets for over 80 years. The iconic Double Diamond signifies the highest quality gears in the racing industry, with products proven as winners at the Daytona 500 and U.S. Nationals for decades. Each gear set is manufactured at their Liberty, South Carolina facility using state-of-the-art equipment and undergoes extensive testing to ensure superior quality and performance.

Note: This is a race-only gear set designed for drag racing applications. Professional installation is strongly recommended.
