Serpent SER110472 Mini Spyder SER440001 compatible 4x7x0.5 shim  [SER110472]

4x7x0.5 shim for precision spacing

The Serpent SER110472 shim is a thin, precision washer for RC shafts, hub faces and suspension link interfaces. Its 4x7x0.5 designation makes it suitable as a spare for Mini Spyder Monster truck assemblies where exact clearance control is required.

Typically, a 0.5mm shim is used to remove minor play between rotating parts, set bearing preload and align gears or wheel hubs. It enables subtle adjustments to axle position, wheel runout and steering setup without changing major components.

Fitting guidance: place the shim over the shaft or bearing outer, stack only matching shims to achieve the necessary clearance, and confirm free rotation and correct mesh after each change. Do not force shims onto imperfect surfaces to avoid distortion.

Adjustment advantage: these small shims let builders fine-tune handling and drivetrain feel with minimal risk, correcting small alignment and backlash problems during setup or after impacts. Keep a selection for routine maintenance and quick repairs.
