After dragging the steps on my 2955RL across a curb, i replaced them with a two=step-set from stromberg carlson:

I used one of these to make up for the bottom step:

as JOLU said, you can get a three-step set from stromberg carlson with less rise per step.
I chose to maximize the ground clearance and went with the two-step and the portable platform step.
