Review: A must have for towing with a newer 1/2 ton - Quick easy installation. Performed exactly as advertised on my 2021 Silverado. No more “Carolina Squat” when I pull my travel trailer. Helped control sway which was not something I expected. (I do use a 4 point sway control/weight distribution hitch.)
Review: 2020 gmc sierra slt crew cab X31 - Edit update: after a month of driving with sumo springs always touching with the spacer, the ride quality is now smoother. Seems like the sumo springs have worn in now and it feels like stock ride. No sag no roll everything perfect. Original post: My truck is leveled. It would sag in the rear when loaded a little bit and while accelerating loaded or unloaded it would sag. I installed this with the spacer on so it is touching all the time. It has fixed my issues no more sag or roll, loaded or unloaded. Even when accelerating the truck is leveled now. The ride feels the same without the extra bounce. Mind you the X31 rides stiffer than the regular ones so i don't notice it. Really happy with the purchase and best bang for your buck, we will see how it holds up in the winter in extreme cold here in Ontario, Canada. I have not seen any reviews for winter. I would highly recommend for leveled trucks or even if your not loaded all the time. It just rides better in my opinion
