Good To Know

Q: How do I know this ring set fits my engine? A: Confirm your piston bore measures 3.875in. and that your build references the 3875VM ring set before ordering. Bore size must match the ring set rather than the outside engine model alone.

Q: Are the rings ready to install out of the box? A: Rings should be checked for end gap and installed to the piston manufacturer's specification during assembly. Verify ring orientation and gap before final installation.

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