Here you have one set (2) of BSA/Sunbeam, plunger carrier column caps, some times referred to as plunger column screw plug or suspension cap top nut.
Made from stainless steel these have been produced to directly replace the original caps, however, unlike the original cap that had a "slot" that easily becomes damaged, these have been produced with a reduced size hex, allowing a spanner to be used.
Part number: 89-4045 X 2
Finish: Polished - Tumbler
These caps will fit the following bikes with plunger suspension:
BSA A7, A10, B31, B33, M20 and M21
Sunbeam S7, S7 Deluxe, and S8
they may also fit other models but please check your part numbers before ordering.
Each of the parts has had at least 3 hours in our tumbler, this gives them a good finish, please see photos! The finish is not "chrome" or "show finish".
This item is made using CNC manufacturing in England by CPC Engineering with high-quality stainless steel.
