The XRAY 381213 graphite upper bumper holder swaps into XRAY M18 and M18 PRO cars to provide a neat, CNC-machined mounting point that resists flex. It is crafted for a clean fit that keeps the bumper secure during aggressive driving.
Graphite is prized for being light yet stiff, which trims rotating mass and reduces unwanted flex. Replacing softer plastic parts with graphite can improve throttle response and track feel without adding ballast.
This part is made for the M18 and M18 PRO chassis and fits using the standard mounting hardware. Installation is straightforward and does not require cutting or adapting the chassis, so it is suitable for quick upgrades.
