YZ-4S Main Chassis Plate, Hard Anodized - S4-002SA by Yokomo  [S4-002SA]

Stiff aluminum main chassis tailored for YZ-4S models

The Yokomo S4-002SA serves as an aluminum main chassis crafted to replace the plate used on YZ-4S series vehicles. The hard anodized finish increases surface durability and supplies a steady platform for mounting electronics, suspension parts, and drivetrain components in standard 1/10 scale touring setups.

The main chassis governs fundamental stiffness and the vehicle's mass distribution. Swapping from the original material to aluminum modifies flex and vibration behavior, which in turn affects cornering balance and suspension feedback. Fit this chassis when you need a consistent reference point for evaluating different damper settings, roll center changes, or mass placement strategies.

Fitment advice: remove all electronics and drivetrain items before replacing the chassis, reuse original screw positions and hardware where they match, and verify servo, ESC, and motor clearances prior to tightening. Check the condition of threads at each mounting location and tighten fasteners progressively to avoid bending. This chassis is intended for scale RC applications and fits the models listed below.

Use the S4-002SA when you require a predictable aluminum baseline for tuning YZ-4S cars; always confirm fitment with your existing mounts and re-check torque on fasteners after the first runs.
