Prothane 7-1606 Differential Pinion Mount Grommet Kit

The Prothane 7-1606 Differential Pinion Mount Grommet Kit replaces soft, worn factory rubber grommets with high-performance polyurethane bushings engineered to reduce differential movement and improve drivetrain precision. Prothane's polyurethane material is significantly firmer than OEM rubber, helping to maintain proper pinion angle, minimize gear lash, and deliver more consistent power transfer to the rear wheels.

Key Features:

• High-durometer polyurethane construction for superior durability over factory rubber
• Reduces differential pinion mount deflection under acceleration and deceleration
• Helps maintain proper pinion angle for improved driveline performance
• Resists oil, grease, and road contaminants
• Direct factory replacement — no modification required for installation
• Includes all grommets needed for a complete differential pinion mount replacement

Prothane polyurethane components are manufactured in the USA and are a popular upgrade for performance street and track applications where drivetrain tightness and chassis feedback are a priority. The 7-1606 kit is a cost-effective way to restore and improve differential pinion mount performance without replacing the entire mount assembly.
