Hey Paul,
The RAS is a great option for some extra support to help prevent sagging without ruining your unloaded ride quality. The HD line has a 3,000lb capacity that only engages as weight is added and starts to press on the factory leaf springs. Other suspension enhancement options can have a noticeable enough difference in your unloaded ride quality to be annoying. If your Sierra has factory top overload springs you'll want part # RAS3611-CHD and if it doesn't you'll need part # RAS3611-HD instead.
If you're handling heavier loads and need more support just let me know what kind of weight you're hauling and I'd be happy to find the best solution.
