This motor mount set includes (2) Delrin mounts for the engine side of the "dogbone" brackets that act as upper, engine-side motor mounts.

In stock form, there are round rubber bushings on the end that attaches to the engine, as shown in the picture below. These stock mounts allow quite a bit of movement, which is not the best for performance or for driving vibration.

These Delrin replacement bushings are each made of two pieces of Delrin, connected with a 6061 Aluminum tube to act as a wear bushing for the bolt.

These mounts will help quicken up shifts, along with the many options for the square mounts on the other end of the dogbones. The car will also be more responsive, as the motor does not lose as much torque into the mounts.

Once on the car, it looks stock, unless one knows what to look for. Installation takes about 30 minutes and can be done with a basic socket set and hammer.

Delrin (Acetal) motor and transmission mounts are each machined from a solid block, and have either Stainless Steel or Aluminum bushings fit into the mounts to act as a point of contact for the connecting bolts. Delrin is an extremely strong and stiff plastic. It is commonly used in place of metal in applications where metal can not be used (magnetic, corrosion, or conducting / insulating reasons). These are much stiffer than polyurethane mounts, and it will not give or wear out. These mounts should never need to be replaced, unlike the stock units which are usually considered a wear item. These will give the same effect as solid metal mounts, without the intense vibration which metal transmits.

These mounts stop the jumping or twisting of the motor under the hood. This movement is caused by the rotating mass of the crankshaft and transmission components. With stock mounts, the engine will twist itself in the engine bay when the throttle is opened, or during high-speed shifts. Over time, this force will destroy the stock rubber mounts. When this happens, the rubber may split or rip, allowing the engine to potentially move inches back and forth. This can destroy CV joints, other mounts, and create even worse wheel-hop.

With these mounts, shifts will be much crisper. There should not be any noticeable added vibration on a car with any suspension modifications, and many times the mounts will smooth the vehicle vibrations by stopping excess movement caused from soft factory mounts. While pressing the gas pedal, a vehicle is much more responsive; as the motor does not lose as much torque twisting into the mounts.

At a price usually less than that of inferior stock mounts, these are not only a great performance item, but a bargain for each application.

Almost any item here can be customized to better fit your needs. Extra charges might be required, but we will try and figure out the best way to make it happen. Please contact us for details.
