Product Details

The Richmond Gear 4900941 is a 3.08:1 ratio ring and pinion gear set designed for GM 8.875 in. (12-bolt) passenger car differentials. This high-performance gear set features 40 ring gear teeth and 13 pinion gear teeth, with a 30-spline pinion shaft configuration ideal for both street performance and weekend racing applications.

Key Features:

  • Superior quality resulting from years of racing development, outstanding design, and state-of-the-art manufacturing methods
  • Ground pinion threads for trouble-free installation
  • 1.625-inch diameter pinion shaft
  • Designed to withstand the rigors of everyday driving and weekend track use
  • Complete matched ring and pinion set sold as a pair

Installation Note: When replacing a 2.73-3.90 ratio, the carrier must be replaced with a carrier from a stock 4.10, 4.56, or 4.88 ratio. This 3 Series gear set fits 3.07 to 3.73 ratio carriers.

Richmond Gear has been the choice of professional racers for over 80 years, earning victories at both the Daytona 500 and U.S. Nationals. Each gear set is precision-manufactured using computer-controlled equipment and special heat treatment processes to deliver maximum strength and reliability for demanding street and track applications.

Great products, and pricing

Very happy with the ease of use and the prices. Best prices all-in! Good selection and will be visiting again for other modifications to my cars. I really appreciate convienence.

Awesome pricing. Needed Pertonix setup for my wifes 62 Mercury Monterey Convertible S-55.

Shipping took about a week total from start to finish. A little slow as far as I'm concerned but the awesome price definatley made it worth it. Will order from them again 4.9/5
