SHOCK BUSH,1/2IN B44/B25
A 1/2 inch shock bush for BSA B44/B25 models, listed under PN 19-5307.
This is a shock bush listed at 1/2 inch, called out for the B44 and B25 model lines in the catalog. It's a rubber or metal bushing that sits in the rear shock mounting eye, taking up clearance between the shock body and its mounting hardware so the shock isn't rattling around on a bare bolt.

Our records show this part under the number 19-5307, with 64533654 as the later factory number it was superseded by, and O190AA as another number it's shown up under. If your parts book lists one of those other numbers, you're looking at the same physical piece.
We don't have much more detail on this one beyond what's in the description. The B44 and B25 designations point to BSA models, not Triumph, so if you're sourcing this for a Triumph don't assume it's the right fit. Give us a call and we'll confirm before you order.
