Hello All, I'm giving thought to updating the cab mounting points on my M37. The springs on the end of the bolt set up seams, well, weird to me. The original system looked like this.


What do you all think about going to something like this?


My thoughts is this is more in line with most vehicles today and it will give you flexibility like the springs did. My only drawback is that it would raise the cab up a little over an inch, which may effect alignment of the front clip sheetmetal.

What are your thoughts?

Hard to tell without seeing them both up close and in person, but doesn't the modern one have a much smaller range of motion than the stock mount?

That's a good question. I don't need to worry about the brake peddle because I'm converting to hanging peddles with the MC all attached to the body. My thinking is why not convert to a more modern way of mounting the body, but I am open to informed input from the members.

k8icu,
If the orig. stuff is in good shape why mess with it? I think both systems accomplish a similar purpose, but the orig. system is a bit "different".

When I did mine some of the isolators were a bit tired so I could see swapping those out, but I don't see any gains in re-engineering the mounts to use urethane.

My 2c, for what it's worth .

Mine were so rusty I had to use the cutoff wheel to get them apart and the drivers side was so gone there was no bolt left. So, I'd have to buy new or good used or change the system and that's where I'm at.

Got it!

I know energy suspension makes a TON of urethane bits. Beware of non OEM rubber isolators. I put an aftermarket set in an old C/10 and they looked worse than the 50 year old ones I replaced within 4 years .

The long bolts & springs were done such as to allow the frame and cab to flex in off-road ops.

Otherwise, no give gets broken body parts.

Chrysler spent a lot of time and $ figuring out what was wrong with the WW2 WC series trucks, and put that knowledge into the G744 series. No wonder they had a good service life by comparison, even if the little flathead was recommended a rebuild @ 15K miles.
