Question:

The 2021 GMC Sierra 1500 AT4 has a factory two inch lift. 1 Will the RAS system fit this suspension? 2 Will the unweighted ride height on this specific suspension be affected? Im researching suspension options that do not add to unweighted vehicle height. Specific products Im researching is the RASfoot and Supersprings.

The # RAS4611 RoadActive Suspension Kit is a confirmed fit for your 2021 GMC Sierra 1500 AT4. This works with your factory 2 inch lift. These springs are customizable and may be adjusted during installation. They also automatically adjust to your vehicle's load. They only down side here is they may increase the height of your vehicle which is what you have asked to avoid.

According to RoadActive, most vehicles fall into the range of gaining 1/16" to 1-1/2" lift. It is hard to determine since there are many variables such as the age of the leaf springs or how worn out they are. They stated that most customers do not even notice the change if there is any at all. Since this is a newer vehicle you will likely fall on the low side of this number, but it is impossible to know for sure.

If this does not work for you then I recommend the # SS65FR SumoSprings Solo Custom Helper Springs - Rear Axle These have a 1,000 lbs. capacity and help support a heavy load to level your ride and minimize sway. These also offer progressive load control, compressing according to the weight of your cargo. Keep in mind, the lift on your truck means the SumoSprings will have to travel further under a heavy load before engaging.

I have attached a video review of both for your reference.
