Hastings, set of 3-3/16" diameter chr/moly piston rings. STD

Standard cylinder: bore 3.187" (80.96mm).
1st ring: 1.6mm.
2nd ring: 1.6mm.
Oil seal: 4.75mm.
Technical tip: Piston grooves vs. piston rings.
It is not difficult to determine whether a Hastings piston ring set will fit a particular piston. You must measure the piston groove height on the piston itself. The top 2 grooves will be for the compression rings, the bottom groove will be for the oil ring. In most cases, Hastings oil rings are the low-tension 3-piece flexible type. Ring heights are listed for reference.
Technical tip: Piston oversizes.
For each oversize, the cylinder diameter will increase by 0.010" (0.254mm). The standard cylinder diameter is stated for reference.
