Prothane Motor Mount Inserts

Prothane's motor mount inserts are crafted out of polyurethane, a material much more durable than rubber that can handle intense weight, heat, and pressure. Designed to fill the voids built into your OE motor mounts, these inserts will drastically increase the power transfer efficiency from your engine to the wheels. Since the voids were initially put there to reduce NVH, it stands to reason that filling in those voids will have the opposite effect. Installing Prothane's motor mount inserts may increase your NVH, but the increase to overall performance is worth it to some drivers. To top it all off, Prothane's motor mount inserts are covered by a lifetime warranty handled in-house here at DST.

OE Motor Mounts

OE motor mounts are usually made out of metal with holes strategically placed to keep most of the engine's vibrations from traveling to the cab. While the OE mounts are decent for the daily driver, the weekend warrior or straight up racer will probably look for an upgrade. Prothane's Polyurethane motor mount inserts offer a great performance boost equal to that of a solid motor mount, without the higher cost.

5 out of 5 based on 8 user reviews. Write a Review

I have replaced all four mount inserts, but not the small cross-member bushings, and I am impressed with them. The outer lip on one of the one-piece mounts tore a little upon insertion, but I cannot say that it was Prothanes fault and Im sure that it still works just as well even with a portion of the lip missing. I have not had them long enough to testify that they last, but they seem like they will hold up and they are currently a massive improvement over my nearly non-existent OEM inserts.

Heard a lot about increased cabin vibration with these kind of mounts but was very impressed with the motor mounts. Very little cabin vibration and is a whole lot better then before, No more lag in my acceleration, great product.

The product shipping was fast. I struggled installing these mounts because of my lack of tools but man o man it was worth that wait, struggle, and sweat. I had to get used to the the new traction, the torque it restored from the beat up old mounts is more than what I expected. Really really happy I bought this.
5 out of 5 - Great product, amazing results!!!

I used the mount set on a 1998 Mitsubishi VR4 and they fitted perfectly maybe you could update your site to show other models the mounts fit not just USA models the only way I found out these mounts would work was though a VR4 forum in Australia
