The PolyproHybrid pinions are a must have part for any Stock racer. Hybrid design consisting of Machined aluminum hub and non slip molded Polymer Gear. The molded tooth profile is much smoother than a typical machined metal gear which makes for quieter and smoother running. We have found these gears to increase initial RPM at the hit of the throttle and improved overall feel of the power delivery and efficiency when compared to heavier standard pinion gears.
