Oil control ring
Oil control ring for the piston, listed under crankshaft and connecting rods, also known by its older E6904 number.
70-6904 is the oil control ring listed in the catalog under the crankshaft and connecting rods heading. This ring works with the piston to scrape excess oil off the cylinder wall on the down stroke and return it to the sump, keeping the engine from smoking and helping control oil consumption.

The legacy form of this number is E6904, so if you're working from an older parts book you may see it listed that way instead of 70-6904 - same physical part either way.
Our catalog record shows this ring turning up across entries from 1967 through 1969, but we don't have a specific model tied to it in our records. Check it against your piston set and bore size before ordering, and give us a call if you want help confirming it matches what's in your engine.
