Power management company 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 percent. “These new ring and pinion sets from Eaton are ideal for the performance enthusiast. Whether for street applications or competing on the track, these sets pair great with Eaton’s broad portfolio of performance differentials,” said Tim Bauer, vice president, Aftermarket, Vehicle Group, North America. “Eaton has a long history of providing quality automotive performance differentials for aftermarket enthusiasts, and these new ring and pinon sets are designed to continue that tradition and deliver on the expectation of quality, reliability and enhanced vehicle performance.” 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 U.S.A. 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; and,• 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.
