Cylinder Casting #
5CU00 = 1999-00
5MW00 = 2001-02 / 2010-11
5UP00 = 2002-21 but works on ALL YEARS, however we only exchange exact casting numbers for what you are sending in as a core
We also have brand new cylinders in stock that do not require a core fee. Call 810-395-7162 or find it in this same section of the site

NOTE: A refundable $400 Core Fee is required. Your core cylinder CANNOT have an iron sleeve in it, nor can it have missing skirts. These will not qualify for core refunds. Typical scuffing, scratching and even aluminum transfer from the piston onto the cylinder wall are completely acceptable. If you have questions regarding if your cylinder will be a good core or not you can always mail us photos, or ship your cylinder into us prior to the purchase. If doing so please label your box "PRE-CORE" and put a note inside with your name and phone number.
When you receive your parts, package your old cylinder and ship it back to our address on the label. Please include the "Core" invoice copy that is in the box with your core when you ship yours back.
Once we receive and validate the cylinder as a good core, we will process it and refund your $400 core fee.
Please note, additional core charges may apply depending on damage to the cylinder
PLEASE REMOVE ALL CYLINDER ATTACHMENTS PRIOR TO RETURNING YOUR CORE (ie. Power Valve, Studs, etc)
