my trail boss was after i installed the pulsar lt.It had a dealer installed bds lift when i bought it so it was never accurate before the pulsar.The zr2 is pretty close.I am changing the swaybar to a hellwig as well as the upper control arms.was confirmed today that the upper control arms are indeed exactly the same as in all other Silverado 1500 models and it was confirmed by the dealership thatany increase in tire weight will increase the wear and possibly a fail of the uppers.Curious, have you actually seen if your speedometer is accurate from the factory? Both my Rebel and Raptor(s) were off 1-2 mph slower from the factory. I'm not sure if Chevy does the same.
