Body mount question

[Frankenchevy]

I am working on replacing my body mounts. I am looking at the original mounts and the new prothane mounts. It seems like the upper bushing’s OD is definitely smaller than the OEM. Is this typical or did I maybe get shipped a 1/2 or 3/4 ton bushing? Bottom half is the same size as OEM rubber, btw.

Anyone know? I’m getting ready to throw them on there.

Prothane’s tech support is a voicemail, lol

They look right. Bushings are the same 1/2 ton through 1 ton.

Awesome, thank you!

Mine from energy suspension were slightly smaller as well

I have the new bushings in, but I’m waiting to torque them down until everything is mounted. Is anti-seize a good idea on the bolts? There was a yellow substance on the factory bolts.

That yellow stuff may be a mild threadlock. Unless it's an internal engine bolt, I still use anti-seize on every bolt I use.

Definitely going with anti seize before thread lock, lol. I’ll be pulling the body again in a couple years. I was lucky to have all mine come out. I was praying I wouldn’t have to cut any holes to get them off. Every turn of the ratchet, I was waiting for something to shear.

Been there, done that too many times!

Sheared a few myself, much to my dismay. Some of those '10 minute jobs' turned into 3 days.
Since I tend to keep my vehicles, and am always trying to 'improve' something it really pays to put anti-seize on them all for me.
Saves me and the neighbors from a lot of harsh language.

Don't waste your time waiting on Prothane. I talked with them directly as when I received my bushings the instructions said to match up the new ones with your old ones. Lets get this straight...match up a 40+ year old rubber bushing that is collapsed, dry rotted and not a very good way to ensure you are putting the right parts in the right places. I threw them back into the box and bought the Energy Suspension where the instructions had the locations identified for which part numbers that matched the part number on the bushing itself. What a concept!?

Sorry I was so re-frustrated when I was writing this I lost my train of thought on the above comment...when I talked with Prothane directly they told me they had no more information than what the original instructions had already told me. How can companies continue to sell products without proper instructions? Replacing the bushings is not something that you want to do a second time after you realize you put the wrong one in the wrong spot. Get the Energy Suspension poly versions and know you have positioned them correctly. My option anyways.

I’m waiting to reinstall my bed to make sure everything lines up right. If not, summit will take anything back.

I just replaced mine with Energy, they seemed smaller but fit well. Everything lined up as it was suppose to.

Mine were smaller and I got the OEM style replacements from LMC. Also I got replacement bolts for the radiator core support and the lock nuts on those things where so damn tight I finally just tossed them and went and got some regular nuts to tighten down. Not sure if it was the Nylock parts causing the issues or not but I just needed to put the front clip on so I could tow the truck without all kinds of trash going into the motor. I'm in the process of tearing it all back apart now so I can paint the engine bay, fenders, and drivetrain, so I will revisit the hardware when it comes time to put it all back together for the final time, but it was a PITA to get them seated on the radiator core until I put normal nuts on them. You probably wont run into that with body bolts though.

What has been your guys experience when going to poly body bushings? Did it make the ride drastically harsher? Or do things just seem to be more solid?
