Designed For Drag Racing Only. Pro Gears may be necessary when tooth breakage occurs with Standard gear sets. Produced from a softer material, the teeth can flex as opposed to crack and break. The life expectancy can vary anywhere from 15 to 300 runs depending on the vehicle. If a Standard gear provided acceptable life, a Pro gear may not be the right choice. - Machined From 9310 Forged Steel. - Heat Treated to Optimize Material Properties. - Matched Ring & Pinion Set. Ring Gear – 9? OD – Tooth count 39 – 10 bolt holes – 7/16?-20 RH threads Pinion – 28 spline shaft – Tooth count 6 – 3/4?-20 RH threads
