RING SET TRIUMPH 500 UNIT +.020 - GRANT
Grant +.020 oversize piston ring set for the Triumph 500 unit twin.
This is a Grant piston ring set sized at +.020 over, made for the Triumph 500 unit-construction twin. It's an oversize set, meant for a cylinder bore that's already been machined out twenty thousandths from standard, typically during a rebore to clean up wear or damage.

Ring sets like this one are matched to a specific bore size, so the +.020 stamp on the box isn't just a label — it's the actual dimension the rings are ground to fit. If you're not certain your barrels have been bored to that size, check before you order, since a ring set cut for the wrong bore won't seat correctly.
We don't have much more on file for this listing beyond the Grant branding and the +.020 size, so if you've got questions on ring count, gap, or exact bore spec, give the shop a call and we'll sort out fitment before it ships.
