I want to get the front end of my '55 Chevy up about two inches using the stock A-frame setup. Does anybody make tall coils or should I use new stock coils and add doughnut spacers? Thanks in advance.
Those will be too tall and slam the upper control arm onto the frame, if you install ball joint spacers they will work but it will raise you 5 inches not 2. see: Duke
ecklers make big block coil for tri-fives.. they are suppose to put a tri-five back up to stock height when you install a big block... i used them and ball joint spacers to get a little height... but looking back i would have used a set of hi-lift/or drag springs with the spacers to actually get weight transfer. because the heavy coils just lifted the front and they had no travel... i'd do 90/10 shocks w/ drag coils, and 4 leaf springs in back w/ a set of 50/50 shocks... and traction bars.
