Zipper’s has developed 3-13/16” bore aluminum alloy cylinders for 883 and 1200 engines to increase the engine size to 88” with the stock stroke crankshaft. These cylinders are manufactured with high quality cast-in iron liners and will work in all types of performance applications. Un-honed cylinders can be fitted with your choice of several piston designs to accommodate specific usages (Zipper’s can provide this service). Includes design improvements for structural integrity, plus cooling fins have been increased to improve heat transfer. Note: Cylinders for 2004-up Sportsters® have ¼” more fin circumference to match the newer cylinder head fin configuration. Cylinders only; order pistons, head and base gaskets separately. Multiple thickness base gaskets are available to allow the engine builder to set piston-to-head squish.

Zip Tip! 3-13/16” is the largest bore size that the stock H-D® XL cases can be safely bored for. 3-5/8” bore is the maximum S&S replacement XL/Buell cases can be bored for.
