Why Use Motor Mount Inserts?
- Increase Horsepower
to the Ground
- Reduced Wheel Hop
- More Responsive Motor
The first and foremost reason for firming up your
motor mounts is to hold the engine more firmly in place. Often the more pliable
stock motor mounts will allow the engine to move too much - resulting in wheel hop
and a loss of power. The more extreme version of this is when a an owner has increase
the vehicle's horsepower more than the stock motor mounts were meant to handle.
This can cause tearing the stock motor mounts as well as damage to the engine and
engine bay should the engine be allowed too much movement.
Will This Kit Work on My Motor
The mounts you're working with MUST have voids
in them like the mounts shown here. These voids are what you will be filling
with urethane. Without voids - there is nothing to fill! Most FWD vehicles will
have several mounts designed like this.
Which Mounts Should I Use?
Most FWD vehicles have several different motor mounts
- typically from 4-5 mounts. Some of the motor mounts are designed significantly
different from the others. TORQUE mounts are the motor mounts designed to reduce
the amount of engine movement when power is applied. Main Mounts are the mounts
designed to support and hold the weight of the engine.
TORQUE mounts are the most effective mounts
at providing a great rigidity to the engine assembly without transmitting as much
natural vibration to the driver. Torque mounts are typically located at the front
and or rear of the engine. Main mounts are typically located higher on the engine
assembly as the engine weight usually hangs from these.
While it is typically possible to firm up all the
mounts on a vehicle - the torque mounts will provide the best trade off of performance
What is Required to complete this Project?
Liquid Urethane - available in
60A, 80A or 94A - (select your desired hardness level
The following items are not included in this kit
and must be purchased at a local hardware store. These can be purchased for approximately
Duct Tape - Seals
one side of the mount
Contact Cement - Helps the
duct tape seal against greasy surfaces
- Cleans the mount of grease and oil to ensure an easy
in a box - vital to the project - don't skip this one.
How Fast does the 80A Polyurethane Cure?
At room temperature the 80A polyurethane cures in about 96 hours. You can accelerate this process by curing your mounts at 150 degrees Fahrenheit. Doing this decreases the cure time to about 18 hours.
What Level of Hardness should I use?
There are a number
of firmness or "durometer" levels offered. The default is 80A as it's the
most used and most popular. These are:
60A - For the Daily Driver - This is the softest
formula offered that will still make a noticeable difference in vehicle performance.
This softer formula is best for tuners that still want to increase performance without
trading off as much personal comfort.
80A - Even trade off between performance and vibration
when it comes to motor mount inserts. This formula is the most popular for it's
ability to significantly increase vehicle performance while still allowing some
small amount of flex in the mounts to keep vibration and noise to reasonable levels
94A - Race Quality - Not for the daily driver.
This formula is the hardest of the 3 available. Providing the best reduction in
motor movement - this version will also allow a rather significant amount of engine
vibration to be transmitted into the vehicle.
Is one kit enough to complete my project?
One kit includes 16 ounces (about 473 mL) of the Liquid Urethane. On
most vehicles this will be enough to complete the project on ALL the mounts on a
What Kind of Quality Urethane is included?
This kit includes 16 ounces (about 473 mL) of the highest grade liquid
urethane available for a project like this. This product has been proven to work
well for creating motor mount inserts and lasting for the life of the mount.
