Sir/Ma'am,
I leased a 2021 GM 1500 crew with 3.0 and 5'8" bed and four wheel drive in DEC of 2020. Powertrain is great! But besides wishing I would have went with a 6.5 foot bed I find the truck has way too soft a rear suspension. The body rolls excessively in corners and squats quite a bit with a load of mulch. Since it is a lease I must remove any suspension upgrades before turning it in per the dealer. Any thoughts on how a Road Master Active Suspension kit might work on this thing or any other recommendations from those that haul or tow with these half tons? Thanks so much in advance for your precious time and wisdom!

You could look to see if someone manufactures a larger rear sway bar...

Thanks sir

If it has coil springs, you could look for rubber inserts that slip in between the coils to stiffen the ride...

Thanks sir. It has a progressive leaf setup on it.

I turned my 1500 lease in with a front/rear leveling kit along with an airbag setup with onboard compressor. I didn't have to take any of that off. I was told "if it adds value" you can leave it on. Might want to double check with the dealer on having to remove any upgraded parts.

Sir- thanks for the notes Bruizza. I had checked with dealer and that is what they told me.

Turn it in to a different dealer haha. Kidding aside that is a bummer they told you that you have to take everything off if you upgrade it.

Roger that lol! This dealer hasn't been fun to deal with.
