BSA VALVE KEEPER SET (8 PCS)
A set of eight valve keepers (collets) for a BSA engine, sold as a complete set.
This is a set of eight valve keepers (collets) for a BSA engine, not a Triumph part despite what the shop's internal tag might suggest. The description on file plainly calls it a BSA valve keeper set, and the number 51023-4 is the earlier form of the same part.

Valve keepers are the small tapered locks that seat into the top of the valve stem and hold the valve spring retainer in place under spring pressure. A set of eight covers a typical four-valve-per-cylinder count on a two-valve-per-cylinder twin, two keepers per valve.
We don't have much more on file for this one beyond the basic description. If you're sourcing these for a specific BSA engine, give us a call and we'll confirm fitment before you order.
