Yokomo BM-670WP B-MAX4W Slipper Plate Replacement  [BM-670WP]

Slipper plate designed for B-MAX4W cars

The Yokomo BM-670WP is an aluminium slipper plate manufactured as a direct replacement for B-MAX4W series off-road RC chassis. It supplies a uniform contact surface for the slipper clutch so engagement can be adjusted with consistency, helping to manage torque transfer into the drivetrain.

Installation is straightforward for those used to working on drivetrains: remove the nearby cover and slipper components, install the plate in the original orientation, then reassemble and confirm clearance and engagement. Do not force components and ensure smooth rotation prior to running.

Tuning emphasis with this component lies on the slipper nut preload and how it affects traction and launch. Increasing preload sharpens initial bite but may introduce wheel hop; reducing preload softens starts and lowers stress on drivetrain parts. Make incremental adjustments and trial runs to find the best setup.

Maintenance involves periodic checks for scoring, clearing any debris from the slipper area, and swapping the plate when wear becomes evident to uphold predictable clutch function.
