Hi everybody. Andy here with etrailer.com. Let's take a look together at this Helwig adjustable rear anti-sway bar. Now this rear anti-sway bar is specifically designed to fit your 2021 and newer Cadillac Escalade, Chevrolet Suburban and Tahoe, and your GMC Yukon. Now on custom fit parts such as this anti-sway bar, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this will work for you or if we have something comparable that will work for you.
This bar is designed to fit your vehicle and work in conjunction with its suspension system, attaching to the rear axle and to the chassis using the weight of the axle to brace the frame as it shifts and turns. This bar is going to help minimize side to side movement, improving the overall stability of your vehicle. and this system is going to let you execute turns and quick maneuvers with confidence providing a level ride for you even on irregular surfaces. It's also gonna help reduce driver fatigue by minimizing the effort required to keep your vehicle in line. This is going to help diminish the effects of shifting cargo, passing motorists, and crosswinds.
This anti-sway bar does for side to side movement, what a good pair of shocks does for up and down motion, giving you a marked improvement in the overall stability of your vehicle. And as soon as you install this, you are gonna feel the benefits of having this installed on your vehicle. Hopefully you can see here along the sides, we do have three adjustment holes. It's going to allow you to choose the degree of stiffness. The holes that are closest to the bar is going to be the stiffest setting, and then the holes that are the furthest from the bar is gonna be the softer setting.
These bushings are made of polyurethane instead of the standard rubber variety for a longer lasting system. They're durable and they're resistant to damage caused by oil and gasoline and ozone. So less wear means less given the system and better overall support. This bar is one and a quarter inches in diameter. It is made here in the USA of solid heat treated chromoly steel giving you that superior strength.
And I would like to zoom in overhead to give you a closer view of this finish. This bar features a silver vein hammer tone finish, which not only gives you protection from corrosion, but the finish itself actually has little divots in it. So when you grease your polyurethane bushings and slide them on the bar, this finish is going to do a great job of holding that grease in the bushing to prevent them from squeaking. A great set of instructions are included to guide you through the installation process, and this does include bushing lubricant as well. And this does have a limited lifetime warranty from Helwig. Well, that's gonna wrap up our quick look today. I do hope that our time together was helpful for you. Again, my name is Andy. Thank you for joining me.

We're glad to hear you've continued to see improvements in handling, especially when cornering, towing, and dealing with crosswinds. It really is amazing the difference an upgraded sway bar makes!
