Installation Notes and Tips

Verify bore diameter, oversize, and ring groove widths before installation. This set is not file fit, so ring end gaps should be checked against the engine builder’s specifications rather than altered by filing. Clean piston ring grooves thoroughly and confirm the top, second, and oil ring orientations before assembly. Always confirm vehicle year, engine configuration, and bore size against the application listing for Ram 2500 and Ram 3500 models.
