At HammerHeadPerformance.com, we sell original TrailMaster OEM & Hammerhead Off-Road OEM parts. Our parts come from the manufacturer and not a third-party. The quality of our TrailMaster & Hammerhead parts are superb. Too any times, we have seen go kart parts online that claim to be TrailMaster / Hammerhead branded parts or claim to fit TrailMaster / Hammerhead go-karts, but through our research and testing, most of these parts either won't fit correctly or the quality is really poor. Even at a cheap price, these parts are not worth taking a risk.
