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

Polyurethane motor mounts offer improved durability and resistance to degradation compared to traditional rubber mounts. They provide a stiffer connection, which can lead to better engine stability and a more direct feel during acceleration and deceleration.

What does 'Type B Tall' mean for these motor mounts?

The 'Type B Tall' designation refers to the specific dimensions and mounting style that Prothane has matched to certain factory GM motor mounts. This ensures they are the correct height and configuration for a direct replacement on compatible vehicles.

Do these motor mounts come with hardware?

This product includes the motor mounts themselves. It is recommended to inspect your existing hardware for wear and tear, and replacement hardware may be needed depending on the condition of your original bolts and nuts.

Product Details

If you're working on a classic GM vehicle from the late 60s and 70s, these Prothane Type B Tall motor mounts are a solid option for replacing worn-out stock mounts. They fit a range of popular models including the Chevrolet Camaro, Chevelle, and Impala, helping to keep your engine securely in place.

Made from durable polyurethane, these mounts are designed to handle the vibrations and stresses of a running engine. Polyurethane offers a good balance between stiffness for engine control and some dampening to reduce excessive vibration transfer into the cabin. The 'Tall' designation refers to the specific height and design that matches certain factory GM applications, ensuring a proper fit when you're replacing your old mounts. The black color offers a clean, understated look once installed.

Replacing motor mounts is a common job when you notice excessive engine movement, clunking noises during acceleration or deceleration, or if the old rubber mounts have visibly deteriorated. These Prothane mounts are a well-built replacement that will help restore proper engine positioning and reduce unwanted movement.
