It is illegal or bad to stack coil spacers? I have all the right lower and upper arm replacement parts for a 4.5 inch lift and blocks for the rear, but I do not have the shocks yet. BUT i can get ahold of a 3 inch solid spacer and a 1 3/4 solid spacer and stack them to get 4 inches WAAYYY cheaper than I can buying new coils. I hear about people stacking spacers all the time for the coil springs but they are usually 1 or 2 inches. I was just curious. Thanks.
