Description

Richmond Gear Pro Gear ring and pinion sets take it a step further. The gear sets are designed for race use only where hard launches and severe heat cycling occurs. They're made from a softer, more malleable 9310 steel alloy to be more resistant to breakage under harsh racing conditions. These gears feature an outstanding rotating weight loss of up to 6 pounds, ground pinion threads for trouble-free installation, and a special heat treatment for improved strength.
