Buy the trucker series which is the same resonator coil but comes with a 17 inch shaft which should be good enough. Either way, the resonator coil accepts a typical CB mount 3/8 x 24 threaded shaft so you can easily use a longer shaft than 17 inches.I am interested in one of these for my pickup. Need a 22" shaft though just to clear the roofline. Is it easy to add a different riser?

I bought mine on Amazon and added a 36 inch shaft.
