Damper unit
A rear suspension damper unit for the swinging arm assembly, appearing in catalog listings from the early 1970s.
This is a rear suspension damper unit, the shock absorber that sits between the swinging arm and the frame at the back of the bike. It shows up in the parts book under the swinging fork and suspension units figures, so it's part of the rear end assembly that controls how the swinging arm moves as the wheel travels up and down.

The catalog record ties this part number to appearances across several years in the early '70s, but it doesn't spell out a specific model, so we'd want to confirm what you're working with before ordering. Girling made a lot of the suspension units used on British bikes of this era, and the catalog listing here is consistent with that.
If you're replacing one, it's worth checking the condition of the other side too, since they tend to wear out around the same time even though we can't say from our records whether they're sold or fitted as a pair.
Sorry if we got something wrong here. If you think this information isn't correct, .
