Will these mounts make my truck ride rougher?

Polyurethane mounts are firmer than stock rubber, so you may notice a slight increase in vibration and noise transmitted into the cabin. This is a common trade-off for improved drivetrain stability and durability.

What vehicles does this kit fit?

This kit is designed for a variety of 1973-1984 Chevrolet and GMC C/K series trucks and SUVs. Examples include the Chevrolet K10, K20, K30, K5 Blazer, and the GMC K1500 and K2500.

Does this kit include hardware?

This kit includes the polyurethane mounts themselves. It is recommended to inspect your original hardware for wear and tear, and replace any damaged bolts or nuts as needed during installation.

Product Details

If you're looking to firm up the connection between your engine and chassis on your classic GM truck or SUV, this Prothane Motor & Trans Mount Kit is a solid option. These mounts replace your old, worn-out rubber components with durable polyurethane, which significantly reduces unwanted engine and transmission flex. This can lead to a more direct feel when you accelerate and shift gears, especially noticeable on vehicles from the mid-70s to mid-80s like the Chevrolet K10 or GMC K1500.

Prothane uses a well-built polyurethane compound that's designed to last. Unlike stock rubber mounts that can crack and degrade over time, especially under stress, these polyurethane units offer a more consistent and reliable performance. While they will transmit a bit more vibration into the cabin compared to stock rubber, the trade-off is a more connected driving experience and improved durability for your drivetrain components. This kit is designed as a direct replacement for many Chevrolet and GMC C/K series trucks and SUVs from 1973 through 1984.
