Ford 9.5 Inch Pro Gear Ring & Pinion – Ground Tooth Drag Racing Gears
Take your drag racing drivetrain to the next level with the Revolution Gear & Axle Ford 9.5 Inch Pro Gear Ring and Pinion—engineered for maximum strength, shock absorption, and consistency under extreme racing conditions.
Designed specifically for high-horsepower drag racing applications, this gear set represents a major advancement in performance gearing. Revolution Gear & Axle offers a Ford 9.5-inch Pro Gear in a precision ground tooth design, delivering superior gear mesh, reduced noise harmonics, and improved load distribution compared to traditional cut gears.
Why Choose Revolution Ford 9.5" Pro Gears?
Ground Tooth Technology
Unlike conventional pro gears that use a rough-cut finish, our ground tooth profile provides:
- More precise gear engagement
- Improved contact pattern consistency
- Reduced friction and heat generation
- Increased durability under high shock loads
This results in smoother power transfer and better reliability pass after pass.
Premium SAE 9310 Steel Construction
Manufactured from high-quality 9310 forged steel, these gears are specifically engineered for drag racing:
- Enhanced shock absorption for hard launches
- Greater resistance to sudden torque spikes
- Ideal for high horsepower and transbrake setups
Unlike harder street gears, 9310 material is intentionally designed to be more forgiving under extreme stress—protecting your drivetrain during aggressive launches.
