Trailing Arm Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are the trailing arms for a 1/2 ton the same size and fit as a 3/4 ton? Or is there a difference in the two?

Same size and fit, the only difference is that the 3/4 ton arms have a stiffener built into the rear where the "U" bolts go through.

You wouldn't happen to have a pic would you?

I have new rear early classics trailing arms coming next week and my stock ones are coming off I could take as many picts as you might need. If no one posts any I can do it for you next week when I take them off.

you want pics of the 1/2 or 3/4 ? I attached a pic of the 3/4, you can see the stiffener plate lockdoc referred too

Awesome, that would be much appreciated.

eastcoastcivil · 07-24-2009, 10:09 AM

In the pic it almost looks like there is a plate on the bottom of the arm too. Much appreciated, thanks for the pic.

It is and it's longer. It runs about 3/4s the lenghth of the trailing arm, back to frontl.

Sounds like we should all be running 3/4 ton trailing arms then. They should be much stronger and resist pulling apart better.

haha...I broke my 3/4 arms

Subjecting them to 40 years of salt doesn't count.......

Actually, the truck was only in NY for about 4 yrs so far, the rest were Kentucky years. But,...the salt up here is super potent. (I think they have it on performance enhancing substances.)

Has anyone tried the CPP Tubular control arms? That is a good looking setup in the catalog...

They look decent. I personally like the AirRide Tech tubular truck arms better vs. CPP's part tubular, part plate version. ECE's square tube arms are also very nice....

That being said, they don't do anything a stock OE truck arm can't do.
