Hey Jason, thanks for reaching out!

The RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-CHD can be used with the Timbren Kit # TGMRTT35D, but one will make the other kind of pointless to use. The RoadActive will work well for standard cargo loads, but the Timbren kit is better for really heavy loads like your in-bed camper.

The Timbren kit will likely be a bit overbearing for the RoadActive kit, so I'd go with the Timbrens if you plan on toting the camper around fairly frequently.

How often do you take the camper out?

@JonG, Yes, I have the Timbrens and they helped a ton with "squatting" on my GMC 2500. I contemplated putting on air bags, but went with Timbrens and am happy so far.

Hey Ted, yes Timbrens would be a great option to add additional suspension support to your 2022 Chevy Silverado 3500. For that I would go with the part #TGMRCK25D though over the #TGMRTT35D as it would still give you the support you are looking for…

I definitely recommend the Timbren springs over the Stableloads. I reached out to my contact at Timbren about the differences between the rear suspension models for your 2016 Chevrolet 3500 4WD and he said that the Timbren Rear Suspension Enhancement…
