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

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 serves as a structural brace mounted on the top of the chassis to influence overall stiffness and tune response during drift runs.

The part is described as graphite construction in the source, and should be treated as a replacement or upgrade panel where graphite stiffness is desired. In practice the upper deck changes how forces transfer between suspension towers and the central chassis plate, affecting transient response and steady-state balance in drift setups.

Installation notes: this is a direct-fit accessory described for Drift Master compatibility in the source material, so installation typically involves removing the existing upper deck and securing the SD-003L to the factory mounting points with the original hardware. Check fastener positions and thread engagement, and verify clearance for servo leads and any top-mounted components before first run.

Tuning role: use the graphite upper deck to adjust chassis feel rather than to correct geometry. A stiffer upper deck tends to sharpen initial turn-in and can reduce chassis flex under lateral loads, while a more compliant deck will soften response. Evaluate changes incrementally on the track and pair this part with suspension and tyre adjustments for predictable drift behavior.
