Description

Part #: 320-0460

The S&S Stock Bore Stroker Kit is an economical way to increase the displacement of your engine without any special machining other than fitting the pistons.

MIA's Description

Three-piece assembled flywheels with shafts. Requires no motor case modification. Features a 4-1/2" stroke. For 103" stock motors or motors with factory 95" kits, only a piston kit is required; stock or S&S cylinder heads can be used. Stock cylinders require boring to 3.875". Made in the USA. Fuel-injected motors require recalibration. Installation requires a skilled technician to check all clearances and assembly specifications.
