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

Upper deck overview for Drift Master

The SD-003L upper deck from Yokomo is a graphite component intended for installation on Drift Master chassis. It functions as a top-mounted stiffening plate that affects how the chassis transmits loads and responds in drift conditions.

The part is noted as graphite construction and should be treated as an aftermarket replacement or upgrade when a firmer deck is desired. The deck changes force distribution between suspension towers and the central chassis plate, with measurable impact on transient handling and on-track balance.

Installation notes: described as compatible with Drift Master, fitting normally consists of removing the existing upper deck and attaching the SD-003L to the factory mounting points with the original fasteners. Always check fastener locations, thread engagement, and clearance for servo leads or top-mounted gear before running the car.

Tuning role: the graphite upper deck is aimed at adjusting chassis feel rather than correcting alignment. A stiffer deck will generally quicken turn-in and reduce flex under lateral loads, while a softer deck gives a gentler response. Evaluate effects progressively on the circuit and combine deck changes with suspension and tyre tweaks to achieve predictable drift balance.
