A big improvement in stability starts with a stronger bar. This 1-1/2" diameter rear anti-sway bar ties the axle to the chassis to balance weight transfer and cut down body roll. You’ll feel the difference right away on the highway—less lean in corners, more control in crosswinds, and a level ride that stays steady even when the road isn’t.
Long hauls and gusty days are easier when the rear stays planted. By minimizing side-to-side movement, this setup reduces the steering corrections you need in wind or when passing large vehicles. The result is a smoother, more predictable drive that helps keep you relaxed and in control mile after mile.
This bar isn’t just thick, it’s tough. The 4140 chromoly steel construction delivers superior strength compared to standard 1020 steel, giving you nearly 30% more resistance to sway. That extra stiffness translates directly into better stability and confidence when you’re loaded or towing heavy.
Instead of rubber, the system uses polyurethane bushings that stand up to oil, gasoline, and ozone. They don’t squish out or wear down quickly, so you get consistent support over time. The included heavy-gauge mounting hardware and bushing lubricant make setup solid and long-lasting.
This rear bar bolts right to the axle and frame using the included hardware—no drilling needed. It’s designed to work alongside most popular aftermarket suspension upgrades, so you can add it to your setup without interference or extra modification.

Hey Fred! Reaching out to the manufacturer directly on this is going to be your best bet just because they will be able to confirm fitment for different sized links. They will be able to make sure a different size is compatible since thats not what the original kit comes with. I can send you their contact information, too!

This is a complete game changer when using a truck camper Mine is an Arctic Fox 990. I would list this under a must have accessory when using a truck camper. Unloaded ride when you hit off camber bumps is slightly rougher, but hey its a Ram 3500 dually for hauling heavy stuff. Also the performance when carving twisty canyons with an empty truck is astonishing....Watch out Corvetts, here I come!

I have taken a few trips with the Clatter Cabin now. It’s been enjoyable to drive. Since then I have replaced the exhaust from the engine back with 2 12 inch pipe. I was able to get the pre bent exhaust parts over the axle and clear your rear sway bar nicely. Now she purrrrs!

Install looks great Steven! I can't wait for you to take it out for a spin so you can see the difference for yourself, it is amazing what a upgraded sway bar does to your ride, no more white knuckles for you, or your wife. What big stops do you have planned on your trip to the West Coast?
Do you have a question about this Anti-Sway Bar?
