Recommended Suspension Enhancement System For A 2020 GMC Sierra 1500 That Prevents Sway

Updated 02/02/2021 | Published 01/29/2021

Question:

Will these work on an AT4 1/2 ton Duramax? If not, what will be the best option. Will be towing about 4K miles with 16’ enclosed trailer full of household goods. Have some decent squatting when hooked up with the loaded trailer. Tow often..usually not quite this heavy but sometimes it gets this heavy.

The SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA28 is confirmed to fit your 2020 GMC Sierra 1500. This will be your best option for suspension enhancement since you tow frequently. This bolts on above your factory springs and prevents sway and sag while extending the life of brakes, tires, and factory suspension.

There are several settings that you can choose from when installing the SuperSprings Suspension Kit.
If you consistently have heavy loads, install the helper springs using the upper bolt holes for extra support and ride height. To maintain the factory ride quality and ride height, install using the lower bolt holes. A nice middle option that will add support, height, and ride comfort would be to use the upper hole on one end and the lower hole on the other end. This will ensure that your ride quality and comfort will not be compromised. This system is rated for 1,500lbs, but keep in mind it will not increase your vehicle's weight capacity and you should never exceed your vehicle's towing capabilities.
