These are our custom made bearing spacers, price is $5 for a set of 4. You will use 1 spacer in each wheel, between the bearings.

They are precision machined to be exactly 10.25mm (0.404") wide and perfectly aligned, to fit standard longboard wheels which have a 0.400" bearing spacing.

They are made from the same hardened chrome bearing steel so you do not need to worry about them getting deformed like aluminium spacers.

(please note: some rare older wheels such as kryptos have a 0.300" spacing, and these will not fit)
