Just doing what I do
The 003/003 rear SS springs in my GTS are 130 lb/in and they raise the rear by about 1-1.5”. That means Tim could remove the rear shackles I sent him and maintain the same ride height. The SS springs would also better handle the torque from his engine on acceleration and keep the rear from winding up.FWIW my notes from the Mopar Perf bulletins give only a few stock spring rates but amongst them are 110 lb/in for Formula S and Dart GTS, as well as '65 Station wagon. Heavy Duty Wagon and 383 equiped A-bodies 130 #/in.
