This 4.5mm wheel spacer is tailored for the YZ-2 series and related Yokomo 2WD off-road platforms. It functions as a small tuning accessory that alters effective track width when placed between the wheel hex and the hub.
To install: remove the wheel, position the spacer on the wheel hex or hub, then reinstall and torque the wheel as normal. The product comes as a pair so both sides of a single axle can be adjusted to preserve balance.
Use the spacer for incremental handling changes and to modify tyre scrub geometry; typical goals include improving cornering clearance or eliminating tyre rubbing on the body. Inspect clearance at full lock and during suspension travel afterwards.
