2021 GMC 3500 Squats Towing a 5th Wheel Will SumoSprings Help?
Published 10/15/2021 >
Question:
My truck, a 2021 GMC 3500 with the Denali trim package, drops several inches when I connect to my 5th wheel. I am using the B&W Companion part number BWRVK3300 that bout from etrailer, great hitch. And of course using the OEM puck system. My trailer is less than the rated 20K of the hitch even when I am fully loaded but I still get that 5th wheel squat and it makes the steering lighter than I like. I don't feel as comfortable in this new truck as i did in my last but I don't want to deal with air bags so I am thinking about adding the Sumo springs part number SSR-203-40-2. What are your thoughts?

I really like the SumoSprings Rebel Custom Helper Springs, # SSR-203-40-2 for your 2021 GMC Sierra 3500. You are definitely looking in the right direction for the solution to your 5th wheel squat issue if you are wanting to stay away from air bags.
SumoSprings helper springs are great when towing a heavier load that causes the rear of the truck to sag, 5th wheel squat. This sagging/squatting, happens when the factory suspension compresses under the added weight. This not only causes the rear to sag but often shifts the weight distribution off the front axle at too great of an amount relative the weight on the rear axle and suspension. This causes a lighter steering control and should be addressed for safety reasons.
With the SumoSprings Rebel Custom Helper Springs, # SSR-203-40-2, each spring has 2 pieces, one attached to the frame of your vehicle and the other the axle. These two pieces come together to provide support when you are towing or hauling a heavy load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control.
