In place of the static straps (which I needed on the last two Dodges 2500s but not this Silverado 2500HD for whatever reason) you can install a piece of steel cable and allow it to touch the ground.  I used a vinyl-coated steel cable for one main reason...those static straps don't like being frozen to the ground and the car driven away.  I went through four or five straps before I did the cable trick...they might be cheap, but they get expensive when you're replacing them all the time.


This will help with static shock when leaving the vehicle, but you will still get the static "whine" in the radio during bad storms.  And that must be an "out west" thing as I only ever experienced that in Texas/Oklahoma/New Mexico and once during a severe snow storm (read: blizzard with lightning) in Wyoming.  I've never experienced it on the east coast.


For the record, I was told the same thing with regard to static in the receiver (pull the coax from the radio) when it was occurring, it was to protect the radio supposedly.  I never pulled it, and listened to it buildup and discharge for a lot of miles without any noticeable consequences to the radio.
