These steps are CNC'd aluminum and available in many configurations. They are copied from Peterbilt style but are more of a replica of the stainless show steps that a lot of aftermarket MFG's offer.
Prices are as follows,
Blank box w/ or w/out top step $20.00 each
Box with mounting bracket w/ or w/out top step $25.00 each
Box with air tank w/ or w/out top step $33.00 each
The boxes without top step are more for behind the cab style tool boxes.
Here are some pics,
The ones in the pics are polished but you will be getting raw aluminum, sorry I don't have the time to polish them. I ship these USPS flat rate. I can ship up to 3 pair (6) steps for $5.25 Please feel free to ask any questions!
