Spacer / valve shim signed MOOSE OFFROAD HARD - PARTS (manufacturer's ref: MSE5PK948350).

Forged from cold-rolled 4140 steel (non-sintered), each piece features a machined finish and the size is laser-engraved for quick identification in the toolbox.

• Outer diameter: 9.48 mm

Simple and robust, this spacer fits into your tool kit for timing interventions — clearance checks, replacement of worn shims, or creating a custom shim set. Compatible with many common 450 cc models (e.g. YAMAHA YFZ 450, KAWASAKI KFX 450 R, SUZUKI LT-R 450), it is particularly suitable for quads requiring tight dimensional tolerances. It does not alter engine characteristics on its own: its role is limited to the positioning and mechanical timing of the valves.
