4x7x0.5mm Mini Spyder shim for SER440001 - Serpent SER110472  [SER110472]

Precision 4x7x0.5 shim for small shafts

This Serpent SER110472 is a thin RC washer designed for precise spacing at shafts, hub faces and suspension link joints. The 4x7x0.5 marking identifies its exact thickness and diameter, and it is supplied as a spare for the Mini Spyder Monster truck where minute clearance control is needed.

Use cases include removing axial play, establishing bearing preload and lining up gear faces or wheel hubs. A 0.5mm shim lets you make measured changes to axle height and steering geometry without altering larger components.

Fitting notes: slide the shim onto the shaft or over the bearing outer, stack only identical shims to reach the required gap, and recheck rotation and mesh after each addition. Avoid using shims on rough or damaged surfaces to prevent bending.

Setup impact: small shims are an effective, low-risk way to tweak handling and driveline response, helping to eliminate small misalignments or backlash. Keep a range of thin shims available when fine tuning or repairing after a crash.

A handy precision spacer for workshop kits, providing reliable 0.5mm correction in tight RC assemblies.
