This is a full top end kit for 2015-Current AXYS Polaris 800 snowmobile. 


This is a full top end kit that is essentially an install and go kind of kit.  Each kit includes information sheets with info on how to properly break in your new top end. The difference between the 2015 and 16-current cylinders is the water passage ways below the VES system were press fit in 2015. in 2016 and up they are threaded (more reliable). Because we are all about reliability, we make sure all 2015 cylinders get the threaded water passage just like the 2016 and up!


This kit REQUIRES a core cylinder from you. If you want your new top end kit shipped to you before we receive your core in the mail there is a $750 core charge. For more information on the details of the cylinder core charge please see the "core return information section to the right for more details.


All cylinders from us have the HG7 hone, which really make your pistons and rings last alot longer. See the "HG7 cylinder finish" section to the right for more details on why you should want the HG7 finish.

  • If you place your order there is a $750-dollar core charge if you would like to have us send your new kit before we receive your core cylinder. This core charge is in place to be sure that we receive good useable core returns.Upon arrival of your core cylinder it will be cleaned and inspected things that could considered a core deduction would be busted cylinder tabs that will need to be repaired normally a low core deduction, If the cylinder received damage in shipping that may be external(damage will be assessed as cist if repairs), a cylinder that is cracked into the water jacket and cannot be repaired would be a total loss of core. We need the core returns as speedy as possible if a core return is not shipped back within 30 days of purchase it may result in deduction or loss of core return.

  • -The HG7 cyl finish is a process that we have perfected over many years here at Indy Specialty. Using multi step process to precision hone the cylinder to allow a better finish than any OEM for extended the ring and piston life. The standard honing practice used by most re-plating companies is out dated .Nicasil silicon carbide cylinders are much to hard for the aggressive finish used on old cast iron cylinders…. leaving the cylinder rough like the standard finish will lead to premature failure
