67-72 Sway Bar - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Blazerowner** · 06-18-2019, 03:14 PM

So I was searching for a 73 Up front sway bar to convert my 72 and saw the below link.

Has anyone installed these?

They are a little pricey but I'm thinking of getting them.

Instructions I found for the rear:

Cant find any yet for the front.

I have Addco bars on the front and rear of my Suburban.

They work fine but I had to modify the mounting mostly because of my 2" lift

**Blazerowner** · 06-20-2019, 02:55 AM

Looks like Hellwig discontinued theirs. Any idea the part numbers for the Addco kits? Do you have pictures of the install? I have a 3” lift on my k5.

Someone rigged a later sway bar up on my '72 K2500 using a crossmember made from 6" c-channel. I removed it when I lifted it 4". I have used the sway bar spacers on other trucks I've lifted (73-87s), but I chose to remove it on this truck. I see very little, if any, benefit from sway bars on these solid axle leaf spring trucks. They already have a "firm" suspension that handles flat as a table top. I get a kick out of having a sporty car come bearing down on me as I'm hitting and exit, only to leave them way behind around the ramp. I feel they are unnecessary clutter. I guess if it comes with one I keep it and if it doesn't I leave it that way. I have owned an awful lot of GM solid axle 4wds, stock to lifted in various ways. I honestly see no real difference in handling between with or without.

I’ve read a few people saying the same thing. I’ve wondered if it was worth the hassle. I haven’t finished the work yet to get it roadworthy from my LS swap and lift. I may just do some driving to see what I think before dropping the money on this option.

**special-K** · 07-04-2019, 10:54 AM

That has been my experience. I see sway bars as very effective for independent suspension. I feel no body roll in the four corner leaf/solid axle trucks. They handle flat as a Ferrari IMO, just higher center of gravity

**Ol Blue K20** · 07-07-2019, 11:37 AM

I found on my 4" lifted 89 Burban that if I was going to do some serious articulation I needed to disconnect the sway bar to keep all four tires on the ground. I eventually just removed it altogether and didn't even notice a difference.

**Blazerowner** · 07-08-2019, 02:06 AM

Thanks for the info guys. I think I will just hold off on this and see how it drives. I bought new springs from ORD so I’m hoping for a little smoother ride on the street. The truck is a road and show truck for me so it will likely never see the dirt. I just have too much time and money into it. That’s what my other toy is for.

sweetk30 · 07-08-2019, 12:24 PM

aftermarket lift kit springs on these older solid axle trucks are more firm and tend to not need the sway bar anymore .

so unless you have stock soft or custom soft aftermarket springs i would not bother my self with the sway bar .

i have run my few 73-87 k30's and a k10 with lift kit springs and no bar and 1 even had a snow plow setup that was almost 800-850 lbs extra and no real difference .

**chevy71super** · 07-09-2019, 08:41 PM

I added a front sway bar on the front of my K10 adapted from a square body. I used the riveted factory square body mounts on my 71 from the frame of the donor truck. I flipped them from side to side and they fit amazingly well. The truck has a 2.5 inch lift with 1 inch zero rate "spring".

I feel the truck handles better but agree I wouldn't use them on a truck that is taken off road frequently as they limit articulation.

tbone67 · 04-28-2020, 01:11 PM

Are those the special order ORD springs that take weeks to make? How much of a difference did you notice? Worth it? Front and Rear?

burnin oil · 04-29-2020, 08:41 AM

When I added my swaybar from a 73 up I just welded in a set of mounts and it fit in and worked fine. My truck has 4 inch lift with very stiff springs and the swaybar made a huge differance if you are pushing it hard through the curves. I don't know how you guys don't see a differance. I do not purposely go off reading anymore but the truck is in 4x4 every time I go up the driveway and when I am working in the yard doing winch work or firewood since I live on a mountain. Articulation is just fine. The only issue I have is when the wheel is cut all the way on a hill with wet clay it will sometimes plow forward instead of turning. Then again the backhoe and tractor do the same thing in those locations. Next time I do the hubs I am sliding a lunch box locker in the front. Just my 2 cents.
