Sidecar suspension unit
A sidecar-specific rear suspension unit listed in the swinging fork and suspension units section of the parts books.
SB4/275 is listed in the catalog as a sidecar suspension unit, turning up in the SWINGING FORK AND SUSPENSION UNITS section of the parts books. This isn't a standard solo-bike rear shock — it's built for a sidecar-equipped outfit, where the extra load and different geometry call for a suspension unit suited to that setup rather than the standard rear units fitted to a solo machine.

Our catalog record for this one is thin. We know where it lives in the parts books and that it's a rear suspension component meant for sidecar use, spanning appearances from 1960 to 1965, but we don't have finer detail on dimensions, damping rates, or which specific outfits it was matched to.
If you're running a sidecar rig and think this is what you need, give us a call and we'll go over what you've got before you order — sidecar suspension setups vary enough machine to machine that it's worth confirming before parts change hands.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
