This Arctic Cat F7 cylinder is re-manufactured by Millennium Tech.  We do require a core or core deposit for this cylinder before shipping.  S/H is $18 anywhere in the Cont. US via UPS Ground, $46 to Canada via USPS Priority Mail International, or $60 to most other countries via USPS Priority Mail International.  Local pickup is welcome as well for no s/h cost. This cylinder has an additional core deposit of $100 which is waived if we receive your bad cylinder before sending this one. The easiest way to do this is to send payment along with the bad cylinder core.  Let me know if you have any questions. Thanks, -Paul (616) 693-2538
