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.

Re: Front sway bar diameter
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

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.

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.

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. |

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
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
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.
