The FANGS™ Bumper for Pint V2. It's not hard to assemble, as it uses the same screw mount locations as the stock bumper. Watch the video for a simple overview of how it works.
DO NOT USE ANY THREADLOCK ON THE AXLES! IT IS NOT ONLY NOT NEEDED, IT ATTACKS PLASTIC AND WILL CAUSE YOUR BUMPER TO CRACK! THIS IS NOT COVERED BY WARRANTY!
IMPORTANT! For ease of fitting, loosen the top 4 screws that hold the rails to the controller (under the footpad). This will allow the rails to shift a bit to accommodate the bumper. Tighten them back up when the bumper is on.
