Support ring
Rear wheel support ring, PN 37-3749 (also W3749), from the 1971-1972 REAR WHEEL parts book figure.
This is the support ring for the rear wheel, listed in Triumph's parts books under 37-3749 (also shown as W3749). It shows up in the REAR WHEEL figure for the 1971-1972 catalog years, which is the main window we have on record for it.

A support ring like this sits in the rear wheel assembly and helps back up the hub or bearing components so they seat correctly under load. Beyond that, the catalog entry itself is brief, so we don't have more detail on exactly how it stacks up in your particular hub.
If you're rebuilding a rear wheel from this era, it's worth having this on the bench so you can check it against what's actually in your hub before you put everything back together. Call the shop and we'll confirm fitment before you order if you're not sure it matches what you've got.
Sorry if we got something wrong here. If you think this information isn't correct, .
