This is an optional Revolution Design Racing Products Aluminum +8mm Rear Motor Wing Mount, and is intended for use with the Durango DEX210 1/10 2wd buggy. These +8mm aluminum wing mounts increases the wing height by 8mm compared to the stock mount delivering increased tire clearance at the wing. This is especially beneficial when using straight/flat type wings, but also provides increased down force for improved high speed straight line stability. These mounts are only compatible when used in the rear motor configuration, and are machined from 7075-T6 aluminum and black anodized, then laser etched for stealthy good looks.
