Product Details

The Richmond Gear 6901671 is a high-performance ring and pinion gear set engineered for GM 8.5-inch 10-bolt rear axles. This street gear set features a 4.56:1 gear ratio, providing excellent acceleration and torque multiplication for street performance applications.

Key Features:

  • 4.56:1 gear ratio for improved acceleration and off-the-line performance
  • Designed specifically for GM 8.5-inch 10-bolt rear differentials
  • Compatible with 1970-1981 Camaro and Firebird applications
  • Precision-machined gears for quiet operation and extended durability
  • Heat-treated alloy steel construction for maximum strength
  • Ideal for street performance, muscle car restorations, and mild racing use

Richmond Gear is known for producing quality differential components that meet or exceed OEM specifications. This ring and pinion set includes both the ring gear and pinion gear, though installation requires professional setup with proper shims, bearings, and carrier components. Professional installation with proper backlash and pattern setup is strongly recommended for optimal performance and longevity.
