This is the Yokomo 5.5mm YZ-2/YZ-4 HD Ball End Cap Set. This set has been updated with an increase on the ball part to 5.5mm, to accommodate the updated 5.5mm ball studs. Doing so, Yokomo has improved durability while maintaining the operation accuracy. Even with a heavier vehicle, there is no dropping out and it will be a tough suspension.
