1.9 mm POM intermediate gear spacers

The R31S139 are intermediate gear spacers in POM used on the GRK5-R HRP Full Kit GRK5RYH.

Choosing POM helps to reduce resistance caused by rotational friction at the intermediate gear.

With a thickness of 1.9 mm, they are compatible with the GRK5-R as well as with vehicles equipped with the GRKRCV conversion.

• Reference : R31S139

• Material : POM

• Thickness : 1.9 mm

• Reduction of resistance related to rotational friction

• Used on the GRK5-R HRP Full Kit GRK5RYH

• GRK5-R

• Vehicles equipped with the GRKRC conversion

• 2 POM intermediate gear spacers 1.9 mm

These shims replace the 3 mm and 1 mm aluminum shims used in the original setup.

Changing the thickness causes a shift in the position of the idler gear. Depending on the front motor or rear motorsetup, the contact position with the spur gear may be changed.

It may therefore be necessary to change the orientation of the idler gear shaft in order to correctly adapt the assembly to the chassis.
