Dually sway bar size

I've got a 2003 crew cab long bed dually, 4 wheel drive, automatic. I'm getting the thump that I've tracked down to the sway bar bushings. I put my caliper on the bars, and the front and back are both 1 1/16" (27mm). That seems a little small to me. Any other dually owners out there have bars that small? I talked to Energy Suspension, and I can piece together the parts to replace the bushings if I verify the end link size, but I wonder if larger sway bars would help with body roll.
I would think a 1 ton should have thicker bars, maybe 1 1/4"?

Thanks.

I haven't measured mine, but the both look like the same size and pretty small, I can get under it in the morning if need be.

That is funny I measured mine and they are 27mm. We make stabilizer bar's and we make 33-34 mm bars for a lot smaller trucks and even the Edge.

Thanks guys, at least I now know that somebody didn't grab a sway bar from a Ranger on a late Friday on the assembly line. I wonder why the small sway bars? I'm feeling a little emasculated, maybe a little sway bar envy of the guys with 1 1/4" bars. I might check around for some larger bars before I replace the bushings. I do get a fair amount of sway in the corners, but I also realize it's a heavy truck.

I don't think you will find a larger bar for it but you might. The 27mm had to be tuned for our trucks. Ford always does a lot of tuning sizes (larger/smaller) before they settle on a bar they check it for several parameters.

I guess it's reasonable to assume that the engineers knew what they were doing, so I'll leave it alone, and get new bushings.

If you want a little thicker then 1 1/16" or even thicker then 1 1/4" why not go with a 1 1/2" diameter from Roadmaster.... It does wonders with heavy campers that some carry on the back of the 350's... (BTW, that's my next upgrade)

They also make a 1 1/2 front bar as well. If you want to try a slightly smaller one try Hellwig products they make bars in the 1 3/8" and smaller range, I think.

My truck does not have a swaybar in the rear. I thought it was odd and can only determine that being a base model truck (don't even have overloads) that it didn't come with one. The truck still hauls like a bandit though. I have a gooseneck and a 5th wheel hitch in the back and it has handled everything I've ever loaded in there. Even a 38' jlg platform manlift. (yup, I put one of those in the bed)

Remember folks, Ford is in business to earn a profit.

There are parts that are designed undersized to wear out early OR not installed at the factory at all if the vehicle can perform safely. Ford wants the warranty to run out before you decide you need them so you will pay extra for parts.

While my truck was still under warranty i had several items added to the truck. My dealer was happy to order and install the parts because Ford paid him, but i had to specifically request each.

Remember, Henry Ford would visit salvage yards to learn what parts never sold. He then met with his engineers to redesign those parts to be replaced.
