As a SHO NUT authorized reseller, we are able to offer the original reinforced motor mounts.
SHO NUT Performance Reinforced Motor Mounts are NEW Ford mounts that SHO NUT personally reinforces. The mounts are 'zero-clearance' because he makes sure each mount has no space between the limiting plates he welds in and the rubber body of the mount. This means that to get any flexing of the mount, you actually need to compress the rubber in the mount against the limiting plate. Other reinforced engine mounts designs still allow some mount movement before the limiting pin or plate hits the rubber body in the mount, since they are built with a gap between the limiting part of the mount and the rubber body in the mount, so they will allow more movement than our mounts.
If you put other reinforced mounts in a vice and try to flex them, you cannot tell the difference between them and a stock mount, since even though you are flexing the mount, the limiting pins or plates are not yet touching the rubber in the mount. When you put SHO NUT mounts in a vice and try to flex them, you move the table the vise is attached to.
The front mount gets one additional limiting plate.
The rear mount gets two additional limiting plates (since this mount works more in compression than the front mount), requiring more work (and cost) to reinforce.
The regular units have the limiting plate pressed into the mount body about 1/8" .
The regular ones are intended for normal performance driving up high horsepower SHOs.
The regular ones will allow some motor movement.
These mounts are as close as you can get to solid motor mounts without actually welding the mount solid. However, there is no noticeable increase in noise, vibration or harshness (NVH) for the standard units. The mount is the proper place to limit engine movement, since the mount and it's attaching brackets are designed for such strong forces.
These mounts are guaranteed for life, and WILL be the last mount you buy.
Motor mount replacement requires proper engine supports and hand toold including a torque wrench. Difficulty of installation is a 4 out of 10.
NOTE that the guarantee is for separation of the rubber in the mount from the inner frame. It does NOT cover mounts where the mounting holes/captive nuts or studs have been damaged or ripped off (this has happened), since this is an installation error of not tightening the bolts properly, or simply breaking the bolts attaching the mounts to the engine. If you want to keep the bolts from coming loose, red Loctite is recommended, along with new bolts. It is also worthwhile to double-nut the bolts, and a nut that works well is the V6 Exhaust Stud Nuts (4) N800-152-S2 from the Clutch page. This nut is a tall, high strength M10x1.5 locking nut with a flange. The torque spec is 55 ft.lb. for the two through bolts, and 75 ft.lb. for the nut on the stud that goes through the subframe.
NOTE also that early versions of the mounts had the area around the limiting plate filled with black silicone. This silicone will crack, and such a crack in the silicone is not considered mount breakage - it is normal. The current versions of the mounts do not have silicone between the limiting plate and the body of the mount.
Please also note that the mounts will wear with time, and become a little looser than when brand new. As long as the rubber has not separated between the inner frame of the mount and the rubber in the mount, the mount has not failed - this is simply normal wear.
If you feel that you have excessive movement, make sure that the nut-to-subframe is tight, the bolts are tight, and the brackets that the mounts are attached to are not cracked. Leaving the bolts loose will damage the mounting holes/captive nuts in the mount, so if you have movement, check it right away before the mounting holes/captive nuts in the mount are damaged - damage which is NOT covered under warranty.
A good way to verify what is actually loose is to get under the car and push and pull on the end of the Y-pipe, watching the motor mount area for movement - here you will see if you have a broken mount-to-engine bracket, loose bolts, or a loose mount.
