The Performance Eng F9633LW is a high-performance lightened ring and pinion gear set designed for Ford 9-inch rear differentials. This precision-engineered gear set features a 6.33:1 ratio, making it ideal for applications requiring aggressive acceleration and increased torque multiplication.

Key Features:

• 6.33:1 gear ratio for maximum torque multiplication
• Lightened design reduces rotational mass for improved acceleration response
• Engineered specifically for Ford 9-inch rear end housings
• Precision-cut gears for smooth, quiet operation
• Heat-treated construction for exceptional strength and durability

This gear set is commonly used in drag racing, rock crawling, and other high-torque applications where low-end power and aggressive gearing are essential. Professional installation and proper setup with backlash adjustment, bearing preload, and gear pattern verification are required for optimal performance and longevity.
