The Yokomo BM-670WP is an aluminium slipper plate crafted for use with B-MAX4W family off-road chassis. As a direct spare it presents a consistent contact face for the slipper clutch so you can adjust engagement more predictably and manage torque delivery to the drivetrain.
Installation is suitable for anyone comfortable with basic drivetrain work: remove the surrounding gear cover and slipper parts, fit the replacement plate maintaining the same orientation, then reassemble and verify play and engagement. Avoid forcing components and confirm smooth rotation before running.
Tuning with this plate centers on engagement control and traction. Tightening the slipper preload raises initial bite but may cause wheel hop; loosening reduces shock to the drivetrain and softens launches. Make small adjustments and test on your surface to find the best compromise.
Maintenance tips include inspecting the plate for wear marks, clearing debris, and ensuring mating surfaces remain flat. Replace the component if you observe uneven wear to preserve consistent slipper action.
