Because we were installing the MyRide system, the first step was to remove the manual adjustment knobs from all four shocks. The MyRide kit even includes the Allen wrench you'll need to do this. If there is any gasket material left on the shock body, remove it. We decided to keep one of the manual knobs in our glovebox in case trail damage claimed one of the new air-line fittings. The fittings bolt on with new gaskets, reusing the Allen bolts.
