I have 2 sets of True Shift Step runners about 1/2 used and a set of Bladetech Shift runners that have a ton of life on them.
The True Step runners are profiles at 9'/10' and the Bladetech runners are the stock profile (9'/11'/13').
Both sets of Step steel - $40 plus shipping
Bladetech - $60 plus shipping
All steel for $100 shipping included.
