Ford 9in Ring and Pinion Lightened 600 Ratio

The Ford 9in Ring and Pinion Lightened 600 Ratio from PEM is designed for automotive builders and enthusiasts who prioritize weight reduction while maintaining strength in their rear differential assembly. This gearset features a 6.00:1 final drive ratio, making it suitable for street applications and moderately modified vehicles that require reliable gear reduction and improved acceleration characteristics.

Engineered through precision CNC machining, this lightened ring and pinion set removes non-critical material from the gear bodies while preserving core strength in load-bearing areas. The 600 ratio is appropriate for street driving, offering a balance between acceleration and fuel efficiency, particularly in applications where moderate engine builds and towing are involved. The high-quality steel construction and optimized tooth geometry minimize backlash and ensure smooth operation when installed correctly.

Ideal for mechanics and DIY builders working on pre-1974 vehicles or upgrading existing differentials in classic cars like Mustangs and Torinos, this gearset provides a reliable solution for enhancing performance. Its lightened design contributes to reduced unsprung mass, which can positively impact handling and responsiveness. Whether restoring a classic muscle car or optimizing a differential, this product meets the needs of automotive enthusiasts.
