This Polaris Axys 800 twin 3022554 snowmobile mono-cylinder is re-plated to stock specs with a lifetime plating warranty by Millennium. It comes with the brass fittings as pictured. The part number supersedes to the 3022828. A core deposit of $100 has been included in the purchase price of this cylinder. We will send a core refund once we receive your eligible core cylinder. Your core must be OEM - not aftermarket. Broken skirts or significant casting damage (such as cracks into the water jacket) may not be eligible for core refund. We do not accept core cylinders that have been sleeved (iron liners installed). Please contact us if you have any questions about your cylinder or if your casting number does not match this cylinder. Shipping is only in the lower 48; unless you are purchasing through eBay's Global Shipping Program. If you are in Alaska please contact me before purchasing to check on shipping options. Thanks, -Paul
