So how was the install? I've tightened mine to where I have about a 2"-2.5" max lift factory, but was considering these in the past. Many people said no due to the added stress they add to the bars and the possibility of over tightening and sag of the bars. Eventually, (2-3 years), the truck will become the toy and I'll get the Dixon Bros front suspension and Deaver springs in the rear.
Question about the install: Did you just use a big C-clamp to compress the keys?
