Motor Mount Inserts - Honda Civic - Prothane 81903

Covers Front Rear Left and Right Mounts

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.

starstarstarstarstar" Some of the best money I’ve spent yet! "

Just recently purchased this kit and installed in my 1989 CRX Si. I had been looking into polyurethane mounts but couldnt see paying the price and not get every mount I need in other kits. Im so happy to find this and Im delighted that it was easy to install. I did have my engine out for this process, I highly recommend that you have yours out too if you are changing the rear mount too. I am extremely satisfied with this product.
