My bad... I wasn't thinking 1/2 ton... My 3/4 ton w/ the Diesel is ~7000 lbs dry. When I was talking about putting them on my truck, we were talking 4 or 5 standoffs if I remember correctly to be able to use them for hi-lift etc. I remember the sliders that were on my ZR2 would deflect when the truck was lifted w/ the hi lift. Those sliders had 3 standoffs and the truck was about 5000 lbs dry. I forget the wall thickness and all the specs on them at this point... it has been a few years, but they were very stout units. I suppose w/o being able to triangulate the sliders for proper bracing on any of these vehicles there will be a certain amount of deflection. Just something to think about as far as how you are going to be using them. In my mind, sliders are either put on the vehicle with the intent of using them and REALLY using them, to lift the vehicle, pivot the vehicle around a rock etc. or they can be used for the oh ******* times to save the body.
