Eaton Adds Performance-Enhancing Aftermarket Ring-and-Pinion Sets in Street and Competition Configurations

By SEMA Editors

EatonEaton’s new aftermarket performance ring-and pinion sets increase horsepower, performance.

Eaton has introduced a new automotive aftermarket performance ring-and-pinion product line that provides vehicle enthusiasts the opportunity to choose from a variety of options and configurations to increase vehicle performance and improve horsepower. The gear sets come in two varieties—street and competition—and can be ordered with an optional isotropic Super Finish process, which coats the gears with a highly polished surface engineered to reduce friction, improve wear resistance, increase oil retention and eliminate the need for break-in. The reduction in friction can increase horsepower from 3% to 5%.

Eaton Performance ring-and-pinion gear sets are available in a wide range of axle ratios for Chrysler, Dana, Ford and General Motors axles.

All Eaton ring-and-pinion gear sets are made in the United States and feature:

  • Computer Numerical Controlled (CNC) cut teeth that improve gear meshing, reduce stress and ensure smooth engagement.
  • Rolled splines for additional tooth strength and longer life.
  • Computer controlled heat-treated steel for added durability.

Street series gear sets are made from high-quality 8620 or 4320 steel that provides long life under daily-use conditions, while competition series gear sets are composed of high-quality 9310 steel for the higher-impact resistance needed when competing at the track. The optional Super Finish is available on all Eaton ring-and-pinion gear sets.

To celebrate the releases of its new product line, Eaton is offering a mail-in rebate for all Eaton Performance product purchases made between November 1 and December 31, 2018.

For details on the rebate, and a complete list of available applications and part numbers, consumers can visit their local Eaton Performance distributor, go to or call 800-328-3850.
