I have this cover on my 2021 Silverado and everything works perfectly, both automatic opening and closing. VANISH Roll-Up Truck Bed Cover | Low Profile Tonneau Covers (accesscover.com)
Exactly. You can run stiffer springs and shocks to control body roll at the expense of ride quality. My Silverado 2500 HD had very little body roll because it was sprung for heavy loads. My Silverado 1500 with softer springs and upgraded sway bars has very little body roll now too, and it rides much better than my Silverado 2500 HD.
I decided to install the Hellwig 7781 front sway bar as well on my 2021 Silverado 1500 Crew Cab Short Bed. Not as big as an improvement compared to adding the rear sway bar, but still very significant. Since it's cheaper that makes it a worthwhile investment. Also much easier to install since there already is a sway bar there. Now you can really tell the all-terrain tires are the weak link.
As truck mods go, I give this one a 10. Well worth the cost and the effort. I took Rook126's advice and used the stiffest setting. Now the suspension will take a set in less than half the time it took before and inspires much more confidence.
I'll post another review after driving the truck but right now here are my notes with the installation fresh in my mind. Step 2 (the very first step, actually) is a dinger. To install the U bolts over the driver side frame rail, I had to pull the left rear tire and remove the fender liner. There is a large grey plastic clip at the top of the frame rail holding the brake lines. There is very little clearance between this clip and the fuel tank and to get the U bolt to rotate in position, you actually have to slip the U-bolt under the clip to rotate it into position. Once you get the U bolt in place there is no interference, but there is no other way to get it in there. The frame rails are coated in some black sticky tar that I could only get off my hands using gasoline as a solvent. What a mess. Step 3 (insert hourglass bushings into end links) is also a trick question. Like people mentioned, there are two sizes of bushings, sleeves, and bolts. Small bolt, sleeve and bushing for the sway bar end. Large bolt, sleeve and bushing for the clevis end. If you have an arbor press you can easily fix your mistakes here. And I have five black washers left over that are too small for any bolt in the package. WTF are they for? The nuts that fit the bolts are both normal and lock nuts. You have more lock nuts than are called out in the instructions, so sometimes you should use a lock nut but they don't specifically say so. All in all, the quality of the materials was top notch.
My Hellwig rear sway bar arrives tomorrow. Thanks for posting the pictures. I traded in my 2013 Silverado 2500HD Diesel for a 2021 Silverado 1500 6.2L and cannot believe how much more body roll there is on the 1500 compared to the HD. The HD springs were obviously much stiffer and that does limit body roll. Looking forward to seeing how the truck drives after I bolt this on.
