Product Details

The Richmond Gear 79-0097-1 Pro Gear Ring and Pinion set is engineered specifically for Ford 9.5" differentials in demanding racing applications where hard launches and severe heat cycling occur. This professional-grade gear set features a 4.11:1 ratio with 37 ring gear teeth and 9 pinion teeth, manufactured from premium 9310 steel material.

Key Specifications:

  • 35-spline pinion with 1.500" pinion shaft diameter for superior strength
  • Dual-drilled ring gear accepts both 7/16"x20 and 1/2"x20 bolts (10 bolts each pattern)
  • Made from first-run steel, never recycled material, to handle extreme torque from high horsepower engines
  • Constructed from a softer, more malleable alloy to resist breakage under harsh racing conditions, featuring ground pinion threads for trouble-free installation
  • Up to 6 pounds of rotating weight reduction compared to standard gear sets

Extensive engineering, computer controlled heat treatment, superior strength, and quality make Richmond Gear the clear winner. Richmond Pro Gear sets are designed for race-only applications and have been proven winners at the Daytona 500 and U.S. Nationals for decades.

The only thing negative I can say is I didn't receive emails stating the item was shipped with a tracking number. I did receive the part quickly so I can complain too much about the lack of emails. I will use Autoplicity again in the future.

Fast shipping and exactly what I ordered at a great price!

Everything went well ordering

Time will tell how well these rubber parts hold up.

this was a good experience all the way around. I ordered a Warn snatch block for my winch and it got here really fast and the cost was very reasonable.

We got what we needed quickly when other sites did not have the tires! Thanks.

Excellent service...a very professional company!

Great prices and even better quality and the shipping was very fast will be buying much more
