What is the benefit of using polyurethane mounts over rubber?

Polyurethane is generally more resistant to wear, cracking, and degradation from road contaminants and temperature fluctuations compared to stock rubber bushings. This can lead to a longer service life and a more consistent feel in your drivetrain.

What does a differential pinion mount do?

The differential pinion mounts secure the differential housing to the vehicle's chassis. They help absorb vibrations and control the movement of the differential during acceleration and deceleration, ensuring smooth power transfer.

Are these mounts sold individually or as a set?

These mounts are sold individually. You will need to purchase the correct quantity for your specific vehicle application, typically two per differential pinion mount location.

Product Details

If you're working on the drivetrain of your 1963-1982 Chevrolet Corvette, these differential pinion mounts from Prothane are a solid choice for replacing worn-out rubber bushings. These mounts are designed to help keep your differential securely in place, which is crucial for proper power delivery and handling. Worn pinion mounts can lead to excessive movement in the rear end, causing clunks and affecting how the car drives.

Made from Prothane's durable red polyurethane, these bushings offer a good balance of strength and flexibility. Polyurethane is known for its resistance to wear and tear, especially compared to stock rubber components, and it won't degrade as quickly from exposure to road grime or temperature changes. This means they should last a long time and help maintain a more solid feel in your Corvette's rear suspension.

Replacing these mounts is a common part of a rear-end rebuild or when addressing clunking noises. They are a small part that makes a notable difference in how the car feels when accelerating or decelerating.
