Polyurethane Transmission Mounts $89.95


Heavy Duty Polyurethane Transmission Mounts

This is a heavy duty upgrade from the stock rubber Fiero transmission mounts. The brackets are made from laser cut 3/16" steel. Jig welded to ensure an accurate fit. The polyurethane part of this mount has an interlocking design which means that even if the polyurethane would fail they will never separate. High strength bolts and locking type nuts are used throughout. The bolts that mount them to the cradle are welded in like the factory originals. No need to reach up and use 2 wrenches to tighten the bolts/nuts. All mounting bolts and nuts are included.

When you install these poly trans mounts you may want to consider an adjustable poly dog bone. Once these poly trans mounts are installed, there will be little movement to allow the stock length dog bone to be reused. To ensure a proper fit, consider the use of my adjustable poly dog bone.

I also offer a poly engine mount to complete the mounting of your engine all in polyurethane.


DOG BONE NOTE: My OEM look aluminum dog bone has slots and allows for a wide range of adjustment. If you want the look of an OEM aluminum dog bone consider using my OEM look aluminum dog bone in the manual (harder rubber) design: Click here



NOTE: Fits all year 1984-1988 Fiero. V-6 and 4 cylinder. Manual or automatic transmission. Does not fit 4 cylinders with the single transmission mount.

Note: If you install poly transmission mounts you must use a heavy duty dog bone. The factory type rubber dog bone allows a large amount of engine/transmission movement and in time the poly mounts will fail. I sell adjustable solid or poly dog bones:

Polyurethane Transmission Mounts  $89.95 each


NOTE: I had to raise the price on these. The cost of the parts, laser cut steel, deburring, welding, zinc plate, paint, assemble these is terrible.  I left them at $79.99 for a very long time.




I do not offer free shipping.

Because I use postal flat rate boxes for heavy orders there is no program that can add the proper amount of shipping to every order. So all shipping is added manually by myself after you place your order. That is explained here: Shipping added later explanation 

When you place an order the shipping amount will show $0.00. Soon after you place an order you will receive an email confirmation that shows the amount of shipping that was added to your order.




Shipping:   Shipping is $12.00 (Single mount, Midwest-USA)

If you order both mounts they will ship in a postal flat rate box for $12.00 shipping. If more items are included in the order they may also fit into this flat rate box or if possible I will use the large postal flat rate box. Shipping costs for the large postal flat rate box is around $15.00-$17.00.

Final shipping cost is determined by weight of the item(s) and distance from Milwaukee, WI. Shipping prices quoted are for items shipped to the Midwest area in the USA. If you are ordering a single item or multiple items the total shipping price is determined after you place the order. I try to keep my shipping prices to a minimum and use Postal Flat Rate boxes whenever I can utilize them for an order.
