(RAS®) RoadActive Suspension 3611-CHD | Fits Chevy/GMC 2500&3500 W/Top Overload Spring

This is a great product. I installed it on a 2020 GMC 3500 At4. I didn’t have an overload spring mounted above the spring pack making it even easier to install. It was as stated by other reviewer’s. Easy to install and took longer to take the tires off since I run 37” heavy tires. I gained 1” unloaded and no sag with my heavy trailer! Love this product and wish I would have got it sooner. My ride is amazing not only pulling but unloaded.

If you have an overload spring you must remove it permanently and buy an add a leaf kit to get back the load capacity you have lost. This was not in the online PDF instructions for my model number but the printed instructions that arrived included this. Would have been useful before ordering.
