Good To Know

Q: How many rings do I need for a TX 440 twin? A: A twin-cylinder engine needs one ring per piston unless the piston uses more than one groove. Check your piston design and order the matching quantity.

Q: Can I fit a standard ring in a bored cylinder? A: No, standard rings are sized for stock bore cylinders only. If the cylinder has been bored oversize, choose a ring matched to that bore.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
