I'll recommend the Glow Step Revolution set up also. Went from the OEM 4 step, that had a high first step, to a 5 step Glow Steps.. They are aluminum, very light weight, with legs that touch the ground to give a more solid walk up the steps..Far easier to go up and down then before.
The company is VERY customer friendly and will bend over backwards to do all they can to help with install if help is needed. My wife, self and our two boxers like these steps MUCH better than the bouncy OEM steps. Can't say enough good about the product and the company..5 stars:)
