Serpent 110475 4x8x0.3 Precision Shim Washer for RC Spacing and Tuning  [SER110475]

Precision shim for fine RC adjustments

This Serpent SER110475 shim carries the 4x8x0.3 designation and acts as a thin spacing washer for RC-scale assemblies. It is suited to fine positional corrections where small clearances affect drivetrain parts, steering linkages, or suspension geometry.

Shims of this size are used to eliminate lateral play, set shaft endplay, and build consistent stack heights when assembling gearboxes or steering components. Because the part is defined by its size code, check that 4x8x0.3 matches the envelope required by your chassis before installation.

Install by sliding the shim into the location that needs reduced clearance, then test movement after each small increment to avoid over-constraining bearings or pivots. Thin shims can be stacked to reach intermediate thicknesses, but always re-check preload and free movement after stacking.

Keep shims flat to prevent bending and store them separately from different sizes to avoid mix-ups during maintenance. For model-specific fitment, consult the vehicle parts diagram or official replacement list rather than relying on visual similarity alone.
