A front shock with a separate oil reservoir and an external DSC knob you can turn to make the ride firmer or softer. The extra reservoir gives the oil somewhere to go and somewhere to shed heat, so the damping stays consistent on long washboard roads instead of going soft. Fox lists it for trucks running 1.5 to 2.5 inches of front lift.

why this one — The pick if you already run a leveling kit on a 2020-or-newer HD and want to tune the ride yourself rather than accept whatever a fixed shock gives you. Two honest catches: Fox states an aftermarket upper control arm is required, which is an extra purchase on top of an already expensive shock, and at roughly $1,680 this is a serious spend for a truck that mostly sees pavement.
