This is a solid Delrin (Acetal) front motor mount for SOHC (24-valve) 3.0L V6 equipped Mitsubishi / Mopar vehicles.
The mount is installed just as the stock mount. Once on the car, it looks stock, unless one knows what to look for. Installation is the same as replacing a stock mount.
The stock mounts are a very weak piece. As shown below, the rubber insert is only held on by two small strips of rubber, allowing a lot of engine movement. With an engine of this much torque, the mounts take a massive amount of abuse, and will not last long. Many of these stock mounts have been completely torn in half, resulting in severe wheel hop, damage to CV joints, and thumping sounds from under the hood.
In comparison, this mount is a solid piece that will probably outlast your vehicle. Launches, especially with the 5-speed have proven to be much quicker and more reliable with solid mounts on these vehicles, as they have a good amount of low end torque; which on FWD vehicles can make for interesting launches.
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.
