Ford 9" 4.11 Pro Gear with 35 Spline Pinion Richmond Gear - Produced in Italy

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
