What Would be Difference Between HD and Non-HD Roadactive Suspension Enhancement Kits

Question:

I purchased at least one of the two RAS from Etrailer. One is standard and the other is heavy duty but I can not tell the difference to install on my new 23 f150 4X4. I have measured everything to compare and the springs look the same. Can you tell me how to differentiate between standard and HD? Secondly, would you suggest purchasing / installing Timbren rear and if so what model should I order. The truck has Max TT package.

Did you measure the diameter of the coils of the springs on the RAS kits? The HD kit should have thicker coils and maybe a longer spring in general. I wouldn't recommend going with a Timbren kit in addition to the RAS. This would be a bit overkill and give you a pretty harsh ride quality.
