BB-01 Slipper Clutch Set, chassis spare part

The BB-01 Slipper Clutch Set adds an adjustable drivetrain element to the BB-01 chassis, centering on a gear-integrated shaft with 20T layout and a spring-loaded clutch assembly. By changing spring tension, the clutch alters slip timing and acceleration traction, which can help the chassis deliver steadier power when grip changes across the surface. The set contains the slipper clutch for BB-01 Chassis and is supplied with the core assembly parts: 1 gear-integrated shaft, 1 slipper screw, Plate A, Plate B, 2 slipper pads, 1 1050 ball bearing, 2 spring seats, 1 spring and 1 2.6 mm lock nut. The friction-based clutch action lets the drivetrain absorb part of the initial load under acceleration instead of locking the drive instantly, giving more scope to tune how the BB-01 responds as power comes in. The included spare part 86T gear extends service support for the same chassis platform. This set suits rebuilds, routine maintenance and setup changes on BB-01 running cars. It can be fitted when refreshing worn drivetrain parts or when a different clutch response is needed for changing track grip, repeated acceleration runs or general chassis tuning.
