Front sway bar diameter

Is a factory front sway bar for our trucks 1 1/4 inch? I need to replace my bushings, so I need the right size.

They didn't have factory sway bars 67-72. 73-87 had a couple of different sizes. Measure yours.

Re: Front sway bar diameter

Well, my 69 GMC has a factory sway bar. It is mentioned on the SPID. I've been under the truck, and seen it for myself. I will try to find time to put a caliper on it tomorrow to give you the exact OD of this piece, but the rain is coming down pretty heavy right now, so don't hold me to the time.

Re: Front sway bar diameter

Mine did come from a 70, I just have to measure it with my calipers. I was just hoping someone would know offhand.

Re: Front sway bar diameter

It depends. Stock 1/2 tons were 1-1/8" while the 3/4+ ton trucks were 1-1/4". The majority of aftermarket bars are the larger 1-1/4"...

I would measure just to be sure.

The 67-72's absolutely had optional factory sway bars... GM didn't drill holes in the A arms and frame that are a perfect match for sway bar mounting brackets for nothing...

Re: Front sway bar diameter

Wow, I didn't remember them being that small (mine has the aftermarket 1-1/4").

That's what makes this forum great.

Re: Front sway bar diameter

Were the Suburban sway bars the same size as the 1/2 ton C10s? I took one off a 1970 Suburban and put it on my 1970 1/2 ton C10.

I have a 1 1/16" front bar from a 68 C10 CST. I just got these from eBay, they fit perfect.

Re: Front sway bar diameter

I think if it got power steering it got an antisway bar.
Not saying if it didn't have power steering it couldn't have an antisway bar.

Yep, my 69 does NOT have power steering, and it DOES have the anti sway bar.

Re: Front sway bar diameter

I thought the CST and Cheyenne got a sway bar. I know my Cheyenne Super had one.

Re: Front sway bar diameter

Mystery solved. I got down an measured. Mine is 1 1/8 inch type. I have the new bushings ready to put in.
Does anyone know if there is a rear sway bar.for a C-10 with the trailing arm suspension? The Panhard Bar sort does the same thing, but I've have been told there are sway bars made, which I think would be an improvement
