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

Slipper plate for B-MAX4W

The Yokomo BM-670WP is an aluminium slipper plate designed for the B-MAX4W family of off-road RC chassis. As a direct replacement spare, it serves the slipper assembly by providing a consistent contact surface for the slipper clutch, helping you set engagement and control torque transfer to the drivetrain.

Installation is straightforward for anyone comfortable with basic drivetrain work: remove the proximate gear cover and slipper components, replace the plate while preserving original orientation, then reassemble and check free play and engagement. Do not force parts; confirm clearance and smooth operation before running.

Tuning with this plate focuses on slipper engagement and traction control. Adjust slipper nut preload and test on-track responses: tighter settings increase initial traction but can induce wheel hop, while looser settings reduce drivetrain stress and soften launch. Use incremental changes and test runs to find the balance for your setup and surface.

Routine maintenance includes visual inspection for wear, removing debris, and confirming flat contact surfaces. Replace the plate if grooves or uneven wear appear to maintain predictable slipper performance.
