Recessed screws on kicker require shimming the stock battery box mounts with the included spacer kit. Mid-shift FX models use included shims for mounting the brake pedal backing plate
Shift pattern is reversed when installed in mid-shift models
Kicker arm may interfere with some OEM exhausts. Late-style 'swing-out' kick arm provides sufficient clearance
