RC8B3 Arm Mount B, HRC Team Associated's new RC8B3 Arm Mounts with High Roll Center offer increased ground clearance for greater durability, since the pivots now sit 1mm higher off the ground. Additionally, they allow the racer to run a higher roll center for increased stability on faster, high-grip tracks. Both #81291 Arm Mount A and #81292 Arm Mount B are narrower for added side clearance and durability. All of these mounts are made of high quality 7075-T6 aluminum. 

*All mounts require the updated #81050 RC8B3 Arm Mount Insert Set, available now.
