For hobbyists aiming to extend the service life of their Yokomo BD8 2018, the B8-500DPA resin drive cup protector provides a simple protective layer. It pairs with the aluminium drive cup to act as a sacrificial surface against abrasion.
This protector mounts over the tip of the universal shaft bone and helps reduce direct metal on metal contact that can lead to premature wear. Less friction means the car keeps its steering feel and throttle response longer between maintenance cycles.
Fitting the protector is quick and tool free: seat it onto the universal shaft bone until it sits snugly. Check the part regularly after hard runs and replace it if it becomes deformed or loose, especially when used in competitive or high stress conditions.
