Question:
Hello, At what towing capacity/weight would you recommend heavy duty vs standard when towing a travel trailer? Do you think standard would level out a truck when towing 7,000 lbs? Not sure if I should go with Heavy or Standard. Thanks

Expert Reply:
That's a good question, and in regards to the standard vs heavy-duty (HD) RoadActive Suspension Kit for your 2021 GMC Sierra 1500, the answer really comes down to the amount of sag, as well as the tongue weight you have. For towing 7,000 lbs you are likely to want to go with the HD.
The reason for that is, the HD is best for tongue weight of 600+ lbs or squat of 2+ inches, while the standard duty is for tongue weight under 600 lbs and less than 2 inches of squat. So I do recommend the HD kit for your '21 Sierra 1500, though just to be thorough, I'll list out both fits for your truck:
- Heavy-Duty: RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS54FR
- Standard: RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS4611
The RAS system is a really smart choice for towing with your Sierra, helping level your ride to give you better traction and handling because the brunt of the weight will be on the RAS springs instead of your factory leaf springs.
