Motor and Transmission Mounts

[Caman96]

How many of you still with original motor/tranny mounts? Or if you replaced, at what miles?

Still original at 330 000km.

Impressive, considering the extreme cold they’re in.

Ya...it was a daily from 91(the og owner) and I ran it from 96 until 2003, it's seen a LOT of freezing temps that's for sure. The tranny one was changed as it was ripped apart when I scattered the trans all over the highway. If/when I bLS swap the ol'girl, I'll probably take a boo and change the motor ones since I'll be in there anyway. Honestly never even checked them. Maybe when I'm healed up and before I drop it off the ramps I'll take a look.

I reused the originals off the 198k mile truck I parted out. Figured they'd outlast the motor, we'll see.

'88 K1500 5.7L, Original engine mounts, ~320K miles. Rubber is shot, tried to install Poly replacements but they're not made right.

Looked at aftermarket replacements--thin steel shells, unsafe in a collision.

There's no proper replacements for a K-truck.

Trans mount may have been replaced when I loaned the truck to my goofy buddy. There was a driveline vibration when I gave it to him, and it was gone when I got it back. He eventually admitted that he'd taken it to a shop and they "did something to the transfer case mount".

I would pick it up from the top side, on a lift there's some different avenues, under no circumstance stick a block of wood under the balancer and jack it.

I noticed Off Road Design (ORD), and Schumacher Metal Works both made a race style motor mount. Lots of steel, not a lot of rubber/polyurethane. Seems like a race/extreme duty kind of part, but with no good OEM type options available, has anyone tried these?
