Comes with parkerized cast gray iron compression and oil rings. Used with early style 1929-1949 type pistons with the one-piece cast iron oil ring. Std cyl. bore: 2.745" (69.72mm). 1st ring: 2.3mm (3/32). 2nd ring: 2.3mm (3/32''). Oil ring: 3.2mm (1/8"). Note: OEM 1950-1973 pistons are equipped with 1/16" (1.6mm) 1st. & 2nd rings and late style 3/16" (4.75mm) 3-piece flex-vent style oil rings for improved oil control; for these Hastings rings see 1950-1973 Flathead model years. Above mentioned rings will not fit the 1950-1973 new type pistons. Tech tip: Piston grooves vs piston rings. It''s not difficult to determine if a Hastings piston ring set will fit a certain piston. You should measure the height of the piston groove in the piston itself. The 2 top grooves will be for compression rings; the lower groove will be for the oil ring. In most cases Hastings oil rings are of the low tension 3-piece flex vent type. Ring heights are listed for reference. Tech tip: Piston oversizes. For each oversize cylinder diameter will increase with .010" (0.254mm). The standard bore of the cylinder is listed for reference.

Black wrinkle finished cylinders. Stock replacement S&S cylinders for stock Big Twin Evo models; without pistons. Std. 3-1/2" diameter and std. 5.550" length is for stock 1340cc applications with stock 4-1/4" stroke. Note: Cylinders must be finish bored and honed to fit stock size pistons. Sold without pistons. The advantage is that this will enable you to bore the cylinders as loose; for direct racing; or tight for a quiet engine with maximum longevity.
Silver cylinder finish. 5.565" long (Stock is 5.500"). for 3-5/8 big bore applications. Compatible with stock dimension manifold. Note: Cylinders must be finish bored and honed to fit stock size pistons. Sold without pistons.

Forged Super Duty series for the Milwaukee Eight engine. With hard anodized crown and top ring groove to reflect heat and prevent ring to groove ''micro-welding''. The Line2Line abradable self-lubricating powder coating technique allows zero tolerance installation; final tolerance will be 0.003". The piston creates its own perfect tolerance during run-in; the coating automatically gives the tightest possible & perfect piston to cylinder fit for no piston rock and best possible ring seal. Note: Fits 107" M8 engines. Works with stock 4.375" stroke and stock unmodified heads. Aftermarket 4.25" bore cylinders are required. - 11.4:1 CR - Piston weight: OEM - Engine displacement: 124" - Bore: 4.25" - Stroke: 4.375" (stock 107" engine) - Ring pack: 1.5mm; 1.5mm; 3.0mm - Top land: .230 - Pin number: .9270x2.250x.180-SCR415H - Pin type: Floating - Pin diameter: .927" - Compression height: 1.155" - Crown Type: Dome - Crown (cc): -2cc - Alloy: Forged 4032 Alloy
