The SILVER PKG is a good system but add our complete tire inflation kit and now you have a GREAT system. We call it the Gold Package. Notice that the tire inflation kit includes our new 6 foot extension whip. Ever heard of "zipper burst"? That's when a damaged high pressure tire blows the side wall out while its being inflated. The 6 foot extension with the clip-on chuck allows you to stand away from the sidewall during inflation. The two dual head chucks allow you to reach virtually any style of valve stem that cannot be accessed for the clip-on chuck.
