The Yokomo SD-304DOP is an aluminum option motor mount designed for use on the D-MAX Hiroshi Suzuki Signature chassis. It increases the backlash adjustment range compared with the conventional mount and accepts a broad range of gear ratios, allowing finer spur and pinion setup without altering the chassis mounting points.
Key mechanical changes include a reduced motor-clamp heat sink profile so a motor heat sink fitted with a small fan can be mounted, and an aluminum motor cam supplied for durable backlash control. The mount is supplied as a kit with the clamp, cam, spring and the fasteners needed for installation.
This mount is intended for scale RC tuning where precise backlash control and improved motor heat-sink clearance are required; it supports finer gear ratio adjustments while allowing fan-equipped motor cooling solutions.
