Drift Master Graphite Upper Deck - SD-003L by Yokomo  [SD-003L]

Tuned graphite upper deck for Drift Master

This SD-003L upper deck from Yokomo is an RC-scale graphite component intended for use on Drift Master chassis. It acts as a structural brace mounted on the top of the chassis to change overall stiffness and influence vehicle response during drift runs.

The part is described as graphite construction, and should be regarded as an upgrade or replacement panel when increased deck stiffness is desired. In use the upper deck alters how forces flow between suspension towers and the central chassis plate, affecting both transient response and steady-state balance for drift setups.

Installation notes: this is a direct-fit accessory listed for Drift Master compatibility, so fitting normally involves removing the stock upper deck and securing the SD-003L to the factory mounting points using the existing hardware. Inspect fastener alignment and thread engagement, and confirm clearance for servo leads and any top-mounted items before the first run.

Tuning role: employ the graphite upper deck to tweak chassis feel rather than to change geometry. A firmer upper deck tends to sharpen initial turn-in and reduce chassis flex under lateral loads, while a more compliant panel will soften responses. Make incremental changes on the track and combine this part with suspension and tyre adjustments to reach predictable drift balance.
