Description:

This is an authentic OEM sourced component which is specially designed for use with Briggs and Stratton engines commonly installed on lawn and garden equipment. The purpose of these ring is to provide a tight seal between walls of the cylinder and the piston. A worn or broken piston ring will allow combustion gasses to escape the seal and enter the crankcase, causing low compression and a loss of power. If compression is reduced significantly, the engine will not run at all. Please note this high-quality set is includes four durable metal rings.

Why are these two different piston ring sets for this engine? And why the large price difference?

Did this question help you?

Can I purchase a single ring? The only one I need is the larger, thicker of the set. If not, do you know what part # it would be ( if sold as single ) --- thanks

Hello Becki, thank you for your inquiry. No, you can not just purchase one ring as this is a set and unfortunately they are not sold separately. Thank you.
