Prothane 00-04 Mitsubishi Eclipse 4cyl Rear Motor Mount Insert - Red

What you get with this Prothane part is a single red polyurethane insert designed to fit into the stock rear motor mount on your 2000-2005 Mitsubishi Eclipse with a 4-cylinder engine. This insert is made to stiffen up the factory mount, which can help control how much the engine rocks back and forth under acceleration and deceleration.

Polyurethane is a popular material for this kind of upgrade because it's more rigid than the rubber your stock mount is made of. By filling in the voids in the original mount, this insert makes the connection between the engine and the chassis more solid. This can lead to a more direct feel when you get on the gas or let off, and it helps keep the engine from shifting excessively, especially if you've made other performance modifications.
