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_border" They do what theyre made to do. I just wish the company had spent more time on R & D so I didnt have to grind on my motor mount inserts fresh out of the box. "

These fit into the voids of the motors mounts fine but the ends are so large, the mounts had to be literally hammered back into place with a mallet. Also, the ends were too large to facilitate installation of the bolts going into the block. Since they had already been hammered into place, we werent about to take them back out to trim the inserts down. So we broke out the dremel and ground them out enough to fit the bolts while still in place. Overall, I am happy with them. I no longer get any gearshift "drifting" everytime I get into the throttle. The engime and transmission are firmly positioned now. Yes, there is a little more body vibration, but I expected that from the beginning. Its not even enough to notice after a week or so of driving it; you just get used to it. Functionality is great; the design? Not so much.... Editors note: The fitment of these inserts depend on the condition of the existing rubber mount. If it is in bad shape to begin with the inserts will be difficult to install and some modification will have to be performed. Because they fill the voids of the OEM mounts more vibration and engine noise will transferred to the cab.
