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.

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.

Pretty sure the factory bars on 1/2 tons were 1 1/8, mine is from a 80s 1 ton 2wd is 1 1/4

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...

OEM that ive seen for our era. starts at 7/8"
ive pulled em off square bodys. and they come up to 1 1/4" and they fit just fine

Re: Front sway bar diameter
 

My 67 is a 7/8" stock with a 327 engine.

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.

My 1972 GMC C1500 has a factory sway bar that is 1 1/16".

i replaced mine from summit racing. just entered year make and model and there they where from moog. i used the rubber ones. think they where 1 1/16? and they only had them in blue. perfect fit

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.

Re: Front sway bar diameter
 

Oooh I learned something.

Re: Front sway bar diameter
 

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

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.

Re: Front sway bar diameter
 

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

Re: Front sway bar diameter
 

My 71 has power steering and no 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

Re: Front sway bar diameter
 

I need a 1-1/4 for my 67 GMC. So I read I have to drill the locating holes. After driving this truck over 1000mi this year, I can feel the sway, a sway bar and GV overdrive, this truck is ready for winding roads, and long trips.

Re: Front sway bar diameter
 

hi guys, my gmc didnt come with a front bar. I found a 7/8 at the wrecking yard and put it on. it was better. then I found a 1.250 at the yard and put it on. big difference. btw my a arms were drilled.

Re: Front sway bar diameter
 

I guess I need to go junk yard crawling. Had 2 guys locally looking for sway bar set-up, found nothing.

Re: Front sway bar diameter
 

I have a spare sway bar that was on my '67 c10 when I bought it. It was on the SPID so I'm sure it was factory.
I just went to the garage and measured it. It measures 1-1/16" diameter and has the brackets that bolt directly to the lower A-arms, no links like the aftermarket ones.

Re: Front sway bar diameter
 

Do you know if it bolts up to a C20. 2wd. Or do I need the 1-1/4in.
I wonder if angle from frame to A Frame is different?

Re: Front sway bar diameter
 

What fasteners are used on the A-Frames, std bolts. Or special.
