Solution for Suspension Enhancement on 2021 GMC Sierra 1500 4X4 With Adaptive Ride Control

Question:

I have a 2021GMC Sierra 4X4 with ARC. I was thinking of installing blue sumo springs but I don’t think I can with the ARC. What options do I have?

You are correct, the # SS65FR are not compatible with ARC. This does limit you somewhat but there are still good options to choose from. If you would prefer something that does not require any maintenance or monitoring the best choice is the RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty # RAS54FR.

The RAS kit turns your leaf springs into a mechanically active system. They will help keep you level while improving the ride and reducing sway. These have a 3,000 lb capacity and bolt-on installation. They also feature a 5-year warranty.

For the best suspension enhancement that is compatible with ARC, I recommend the Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle # F2609. These air bags will keep you level while towing and improve steering and stability. These have a load leveling capacity of 5,000 lbs and feature a simple, no-drill installation. Since they can be adjusted they are perfect for any application. They can also be run at the minimum psi so there won't be an impact on unloaded ride quality.

I also highly recommend adding an air compressor like the Firestone Air Command II # F2178. This will allow you to adjust the pressure wherever you are from the cab of your vehicle. This is a dual path system so you can adjust each air bag individually.

I have attached some installation videos for your reference.
