Big end shell set listed for the BSA B25, part number 70-6068.

This part number turns up in our records as a big end shell set for the BSA B25 - not a Triumph part, despite how it's filed in some listings. Big end shells are the bearing inserts that sit between the connecting rod and the crankpin, letting the rod ride smoothly on the crank as the engine turns over.

We don't have much more detail on this one beyond the basic listing. If you're rebuilding a B25 bottom end and this number matches what's called out in your parts book, it should be the right part, but call the shop first so we can confirm before you order.
