A 355nation How To presented by

Project Name
How To Install Belltech front and rear anti-sway bars on a Z85

Project Description
Belltech already provides instructions but I figured this how to would highlight and explain some things a little better plus have MOAR PIKTARZ. This how-to will walk you through the parts needed, tools needed, costs, and steps for installing swaybars. The purpose for installing or upgrading anti-sway bars is to improve handling by reducing body roll in turns. You can learn more about sway bars and how they work HERE and HERE.

Belltech instructions:


Skill Level
Easy to Advanced depending on path taken.

Body, text and pics


FYI: The BellTech rear bar can also be installed on a ZQ8, though BellTech says it won't fit. It was the same install as the directions, but I removed the factory bar mounts from the rear axle. Kerad11 said he made it fit w/o removing the factory mounts. - 1BADI5
Lets begin. You will notice my sway bars have been painted differently from how they arrived. This is because when they arrived there were a few chips in the powdercoat/paint it came with and I wanted to cover those. The sway bars make a clear difference coming from stock Z85 front only to having Belltech front and rear sways.

Front and Rear sway bars after they were delivered:

Stock Front Anti-Sway Bar Removal

I set the bar out with the end-links I intended to install with it but I ended up not using them.

So let's start by removing the stock front sway bar. I lifted the truck using the stock jack points and sliding lift stands under the frame for safety. Once the truck was in the air I took off the front wheels to provide easier access to the end-links. To remove the endlinks I used a 1/4" socket and an adjustable wrench to hold the nut and socket to turn the bolt. You can see in the picture below:

You can remove the bottom or top part of the link first, doesn't really matter. However, I found it easier to detach the link from the control arm and once the entire swaybar was out remove the link from the bar. I detached the bottom first on both sides.

Once the bottom of the endlink was detached I began removing the frame mounts for the sway bar using a 10mm socket. When I got to where the bolts were almost completely out, I had a buddy help hold the swaybar up while I removed them completely. Don't want the bar falling on your face, OUCH!

Front Sway Bar Install

To start the install of the Front Belltech Swaybar I lined up the stock sway and the Belltech sway to see where the bushing should go without having to get under the truck. I applied the provided grease liberally to the inside of the bushings and then slipped the bushings over the Swaybar as close to the intended locations as possible and then slipped the metal bracket over them. Don't mind the glove, I was using it to take pictures and not get dirt/grime on it and then forgot to take it off lol.

At this point I had already removed the endlinks from the stock swaybar and put them on the Belltech. I used the same method with socket and adj wrench to remove and install them on the new swaybar.

From there I slid under the truck with the bar and reversed the steps of the stock swaybar removal. My buddy held the bar while I started lining up the bushings and then started the bolts on the frame. Once the bolts were on but not tightened down completely we re-installed the endlinks and then tightened the bolts down completely on the bushings.

Rear Anti-sway bar install

To start the install of the rear swaybar grab your parts and start putting the swaybar endlinks on.

The order of install is bolt -> cap -> bushing -> swaybar end -> bushing -> cap -> short or long spacer -> cap -> bushing -> bracket -> bushing -> cap -> nut.

As a note the long spacer was too long and I had to use the short spacer which fit perfectly. Once you have it all together tighten it just tight enough to stay together.

Now we need to begin attaching the bar to the axle. If you have a Z85 you can just place your u-bolts where needed with the flat piece facing the rear. Make sure to grease your bushings, slide them over the bar, and then begin to attach the bushing brackets to the ubolts. Don't forget your shim/plate that goes between the ubolt and the bushing! Make sure that the swaybar dip/curve is facing downward with the links sticking out upward as seen below.

Just a note that the short side of the brackets is what attaches to the frame. Now that we have the endlinks/brackets attached to the swaybar and the swaybar loosely attached to the axle we can shift around the ubolt brackets if need be to get the bar better centered. Once you have the bar centered you will need to push it up and mark where the brackets are going to attach on the frame.

After marking where the brackets will need to go on the frame remove them from the endlinks. From here there are two paths you can take: bolt them on or weld them on. If you are going to bolt them on this is where you will need a 1/2" and a 3/4" drill bit for the frame.

I decided to have a buddy weld them on for me so after marking where they will go we ground down the edges of the brackets and the outlines for where they will be mounted on the frame.

After grinding everything down it was time to get welding!

After my buddy finished welding up the brackets we let them sit for a bit because they will be HOT. After letting them sit for about ten minutes and enjoying a beverage we bolted the endlinks on to the brackets (which were still pretty warm). Once we had the endlinks installed on the brackets we tightened them down and then tightened down the bushings/ubolts.

Now we take her out for a drive and enjoy your new found handling!

Fresh from belltech. Can't wait to install these. Although I think I need new end links for the front when I put it in.

Have you gotten these in yet? You shouldn't need new endlinks unless your stockers are messed up. You'll love them.

Re: How-To: Install Belltech Front/Rear swaybars
Thanks for the How-to Skizzo.

I'll be installing my new rear bar on my 04 soon. Gonna transfer my existing bar over to Projecton24's 06 after that. He's having a friend fabricate and weld the 2 brackets needed to attach the end links. Two sway bar projects for the price of one!

Re: How-To: Install Belltech Front/Rear swaybars
Welding those rear endlink mounts to the frame is really the way to go.

I have mine bolted in per the instructions and hardware provided with the kit; though I noticed after a few years they have rotated forward abit.

For anyone interested, the Belltech replacement for their swaybar pivot-bushings are part-number 133075, current price is $9.99 for a set of two.

Re: How-To: Install Belltech Front/Rear swaybars
Every time I look at the Hellwig Rear Sway Bar, I think it will bolt up to the ZQ8 trucks using everything stock. I am almost willing to buy one to try it, but if it doesn't work, i would want to sell it. Not willing to cut anything to make it work. I have my belltech worst case.

Any takers on buying a practically new Hellwig Rear if it doesn't work? Lol...

price would be around $200 to $225.

Re: How-To: Install Belltech Front/Rear swaybars
Just wanted to post a thank you for these install directions. I used them to help with the install of the Belltech rear bar in my 09 Canyon. Made a tremendous differance in the handling. Love it!

I have a quick question about if a 1/8-1/4 inch difference in mounting height on the sway bar bracket is an issue? Did my best to install the brackets flush with the frame. Drilled a bit low on one side :-( But haven't noticed any issues.

Now for my tired 130K suspension to get done with new Belltech goodness. Thanks all!
