The Yokomo B8-301AA Aluminum Suspension Mount is a direct upgrade created for the BD8 chassis. It replaces the standard resin bushing and narrows the width relative to the kit's original suspension mount B, giving you an adjustable suspension pin spacing from 39.5mm to 42.7mm for detailed setup work.
Aluminum delivers improved strength and durability compared with resin parts, so it stands up better to the loads of competitive running. Choosing an aluminum mount helps reduce unwanted flex and keeps front-end geometry more consistent during aggressive laps.
The B8-301AA lets racers change the suspension pin distance to tune handling, whether you need crisper turn-in or more stability down the straights. That range of 39.5mm to 42.7mm makes it simple to test small geometry changes without replacing other components.
