Pro Diff Gear Set - 4.88 RatioSuit GM 12-Bolt
Richmond Gear takes it a step further with these Pro Gear ring and pinion sets. The gear sets are designed for drag racing only where hard launches and severe heat cycling occurs. They're made from a softer, more malleable alloy to be more resistant to breakage under harsh racing conditions. Sets with 35 Spline pinions require special large stem pinion supports.
