Frequently Asked Questions

Will this piston kit work with Screamin' Eagle heads?

Yes — the K2795 is engineered to work with both OEM and Screamin' Eagle cylinder heads.

What does +.010 oversized mean?

The piston is .010 inches larger in diameter than stock, requiring a corresponding overbore of the cylinders during rebuild.

Do I need new rings and a pin, or just the piston?

This is a complete piston kit that includes premium compression ring, Napier second ring, and 3mm oil ring — all you need for a top-end rebuild.

Can I use this piston with my stock cylinders?

No — the +.010 size requires that your cylinders be bored .010 inches larger. Have a machine shop verify bore size before ordering.
