SSP-G 1mm Cylinder Spacer for GY6
SSP-G 1mm cylinder spacer for B-Case GY6 engines. Cylinder spacers are used to increase piston to valve clearance when using a stroker crank.
B-Case engines are "big block" GY6 engines with 57mm (or 80.5mm diagonal) cylinder stud spacing.
Please Note: You will need an additional cylinder base gasket when installing this spacer.
