RING SET TRIDENT +.040
Piston ring set for the Trident triple, ground to +.040 oversize.
This is a piston ring set for the Trident triple, ground to +.040 oversize. If a barrel has been bored out that amount during a rebuild, this is the set that matches it up. Our records on this one are thin - just the description and the oversize spec itself - so we can't speak to which years or which specific bore work it pairs with beyond what's printed on the part itself.

The part carries an alternate number, R23020/040, which is worth knowing if your old invoices or parts book show that form instead of the JRC number - they're the same physical ring set.
Give the shop a call before you order if you want to confirm it lines up with your engine's actual bore measurement. Oversize ring sets are unforgiving if the number doesn't match what the machinist actually cut.
