What is the main benefit of using polyurethane mounts over rubber?

Polyurethane mounts are more resistant to heat, chemicals, and general wear than rubber. This means they tend to last longer and maintain their shape and support under stress, helping to keep your engine and transmission stable.

Will these mounts make my car vibrate more?

Polyurethane is stiffer than rubber, so you may notice a slight increase in vibration transmitted to the cabin. However, these mounts are designed to offer a good balance, providing improved stability without excessive harshness for many applications.

Does this kit include everything needed to replace the engine and transmission mounts?

This kit is designed to replace the primary engine and transmission mounts. It's always a good idea to inspect all related hardware and brackets to ensure they are in good condition before installation.

Product Details

These motor and transmission mounts are made with Prothane's red polyurethane, a material known for its durability and resistance to wear. They are designed to replace the original rubber mounts on a wide range of GM vehicles, including models like the Chevrolet Camaro, Chevelle, and El Camino from the late 60s and early 70s. Worn-out mounts can lead to excessive engine vibration and movement, which can affect handling and comfort. Upgrading to these polyurethane mounts can help restore a more solid feel to your vehicle's drivetrain.

Polyurethane offers a good balance between stiffness and vibration damping. While they will transmit slightly more vibration than stock rubber mounts, they are much more resistant to the heat and stress that can cause rubber to break down over time. This means they can last longer and help keep your engine and transmission securely in place, especially if you're driving a classic GM car that sees regular use. The kit includes the necessary mounts to address both the engine and transmission locations, making it a comprehensive replacement solution.
