Prothane Polyurethane Motor and Transmission Mountshttp://ProthaneSuspensionParts.comWith only that drop down selector left, you are very close to replacing those old soft rubber motor and transmission mounts with Prothane's performance polyurethane. This is a very important part on your vehicle. If they haven't already, rubber factory mounts on your Impala will soon wear out and tear away from their mounting brackets. Once this happens, you can expect a lot of rocking to be coming from your motor and transmission. With Prothane's polyurethane motor and transmission mounts, you can provide firm support for your engine and tranny, while still enjoying the benefits of a smooth ride.
Prothane makes parts in 2 colors. Red and Black.
How are these two colors different?
Aside from the actual color, the red parts are essentially the same as the black.
I thought that the RED parts were harder and more performance oriented?
This is a common misconception. The red parts have the same durometer (hardness) as the Black parts and differ only in their actual appearance (color).
