SHIM SET,PREUNIT SWING AR
A shim set for a pre-unit style swinging arm pivot, exact make and model not specified in our records.
This is a shim set for a pre-unit style swinging arm, listed under part number JRC-H304CA (also shown as H304CA or JRC H304CA in some records). Shims like these get used to take up play in the swinging arm pivot, keeping the arm running true side to side without binding on the pivot shaft.

Our catalog entry here is brief, and it doesn't tell us which marque or model this swinging arm belongs to. Pre-unit construction shows up across a number of British bikes of the era, not just one make, so we're not going to guess which one this set was cut for.
If you've got a pre-unit swinging arm with some slop in the pivot, this is the kind of shim set you'd reach for to shim it up correctly. Give us a call with your measurements or the bike it's off of and we can confirm before you order.
