I have always had great luck with SS springs. I bought the SS springs on my boys Dart back around 2000 at the Dodge dealer I worked at and they were the 002 & 003 SS springs. This is the car about 6 months ago as it still sits the same and rides great like any normal car. I also put the 3400 lb SS springs on my 63 around 2008 and it still sits the same and rides good. I also don't get why people say they sit uneven with SS springs because I surely don't leave my cars sitting uneven after putting SS springs on. If they are uneven any I adjust the torsion bars so the car sits level. I have done that on all the SS springs I put on in my life and they all ride fine and work fine. But I have not bought any SS springs since 2008 so I cant speak for the quality of them since then. I also am not using a pinion snubber with my SS springs as I found it made no difference when I tried it with the SS springs. Ron
