6" Zone lift preload spacer

[Chris DeCuir]

Can anyone tell me how much lift the preload spacer actually gives in the Zone 6" kit? I have bils set at 2.8 and installed my 6/5 Zone kit last week without the preload spacer. The truck still sits about .5" high in the rear.

The top spacer is 5" tall, preload is approx. 3/4"

what are your fender measurements?
