May be a bit of a stupid question, but I got the toytec boss suspension and am wondering how to adjust them so that they're at 3"? It says they come loaded at 2.5" but since I got the HD rear coils I don't want it to sag in the front especially since I'm putting on my shrockworks bumper at the same time I put on the suspension. Is it better to adjust it while it's off the vehicle or better to do it while it's on? I won't be installing it and I'm worried the guy who is wont get what I'm saying! Thanks for the help guys!
