I was glancing at my front shocks earlier today because they didn't look stock. I guess I never really looked at them before, I've had the pickup since October of last year. They are SVT+ Mopar Premium Duty Shocks.

Next to the SVT+ it says "Smart Valve Technology".

My question is, are these any good? I understand that a Rancho or Bilstein would undoubtedly be better, but has anyone heard of this type of Mopar shock before? I cannot find any information about them in the forums or on the net.

EDIT: I found one page of info, but it doesn't tell me much.
