Hey Brian. The SumoSprings Solo Custom Helper Springs item # SS45FR are what you need for your 2024 GMC Sierra 1500 with the X31 offroad package. These have a 1,500 lbs capacity and will help soften the ride and keep your rear end level when you're towing a trailer or hauling a heavy load in the bed.

The SumoSprings item # SS45FR will replace your factory bump stops so there's no compatibility issues with the X31 trim.

Are you towing a trailer or carrying heavy loads in the back? What has you looking at suspension support?

I had these on my 2019 High County I used these in addition with RAS. The sumo springs all but eliminated the proposing I was experiencing. And improved overall ride. Hope this helps.

I put them on my 2020 GMC diesel truck because I was pulling a 33’ camper to Florida about 1100 miles. They have done the job to my satisfaction. I did not use the spacers because I didn’t want to engage the springs when not pulling the camper. I saw little change in ride after putting springs on when not pulling a camper but had a better and safer ride after putting them on while pulling my camper.

I drive a 2020 Chevy Silverado 4x4 1500. I am very happy with my Sumo Springs. Easy to install & work as advertised. I pull a 30 ft RV camper & the springs add greater stability, keeping my frame from bottoming out like it did before. The springs add an additional 1500 lbs capacity to my truck. If you’re driving on a rough road with pot holes or off-roading, your rear axle may bottom out, so you’re going to feel the effect of the springs more than normal street driving, but it’s more than acceptable. My wife doesn’t feel the effect of the springs at all driving under normal conditions. You’ll not regret installing them. The set comes with a 2 inch spacer in case you have raise the body of your truck higher than factory standards.

I purchased these to level out my towing and they work great. I live in a northern state where it gets to below zero and the springs do stiffen up but not so bad as to not have them. In comparison it makes the truck ride more like a “heavy half ton”. I would recommend them to anyone.

Thank you Jerred for getting back to me. I will be towing a Brinkley I 275 travel trailer which the dry UVW is 7485Ibs and GVWR is 9600 Ibs, and the hitch weight ( pin weight) is about 705 Ibs.

@BryanV You're welcome! That's a super nice setup you've got. The SumoSprings item # SS45FR are definitely going to help keep your Sierra's rear end level when you're towing.

I was wondering also if could recommend a good weight distribution hitch that would work good with the set up that I described to you. I would appreciate Thank you.
