SHOCK ABSORBER
A clutch-assembly shock absorber (cush-drive component) listed under the CLUTCH AND CHAINS figures, 1963–1964 catalog appearances.
57-1667 is a shock absorber that lives in the clutch assembly, not out on the suspension. It shows up in the CLUTCH AND CHAINS section of the parts books, where it works as part of the cush-drive setup that takes the harsh edge off power delivery through the clutch and primary chain. The legacy number for this one was T1667, which is how it would have been listed before the modern numbering system came in.

Catalog appearances put this part in the 1963–1964 window, so if you're working on a bike from outside that span, get in touch and we'll help confirm before you order.
Given how narrow the catalog window is here and how little detail we have beyond the figure title, we'd rather be upfront that this is a case for double-checking against your actual clutch assembly before ordering.
