TEAM ASSOCIATED B74.2D TEAM KIT AS90037TEAM ASSOCIATED B74. 2D TEAM KIT As tires, motors, batteries, and tracks evolve, Team Associated adapts and improves with every iteration of the RC10. The engineers at Team Associated's Area 51 set out to extract more performance from the RC10B74 4WD buggy platform with the introduction of the RC10B74. 2 and RC10B74. 2D. Our goals were to reduce overall weight, lower the center of gravity, and improve jump and bump handling. We exceeded expectations.
