CJT123, I would wait and see, the Amp steps are $1,000 plus install... Let that sink in.
If you hit a rock and mess them up... well they don't like to sell parts, just kits.
I have a set on my 2011 F350 (I tow A 32FT trailer) There great on that rig, but I don't rock crawl with that beast.
I'm sure you can purchase a set, I got mine @ Extrememotorsports in Brentwood CA
