this is a home made lift i made for the blazer but decided not to use it, was installed but never drove. pics can be seen here they measure 20in and have the hole for the center bolt 4in back from edge and i think the uprights are 8in high. will take 50 obo plus s&h just want to get rid of it, there are 4 traction lifts i will sell in pairs if i have a buyer for both pairs. no hole have been drilled in the up rights. thanks, chris open to trades too.
