Skip to product information
Used with 3-5/8" large diameter pistons using 0.078" (2.0 mm) compression and 3/16" (0.186") (4.75 mm) oil rings.
Standard cylinder bore: 3.625" (92.075 mm). 1st ring: 2.0 mm. 2nd ring: 2.0 mm. Oil ring: 4.75 mm.
Note: When using 3-5/8" S&S pistons, in virtually all cases the Hastings Rings for S&S pistons referred to as 'S&S 3-5/8 Big Bore' should be used.
These come with 1.6mm compression rings and 4.0mm oil rings.
Please check before ordering.
Tech Tip: Piston Grooves vs. Piston Rings
It is not difficult to determine if a Hastings piston ring set will fit a particular piston.
You must measure the height of the piston groove 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 of the low-tension, 3-piece flexible vent type.
Ring heights are listed for reference.
Tech Tip: Oversized piston.
For each oversized cylinder, the diameter will increase by 0.010" (0.254 mm).
The standard cylinder bore is included for reference.
