Good To Know

Q: Can these rings be used with a standard bore piston? A: No, these are .060 over-sized rings and require a matching .060 over piston and a cylinder bored to 98.1mm.

Q: Are these rings compatible with other bore sizes? A: No, they are specifically sized for 98.1mm bore applications; using them on a different bore will cause poor sealing and potential engine damage.

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