To get optimal performance out of your Arctic Cat, you need to gear it right. We offer a complete lineup of gears to fit your needs. Made of heat treated, case-hardened 8620 high-alloy steel, Venom Products CNC-machined sprockets are made in an ISO 9000 certified facility right here in the USA. These are much stronger than OEM powdered metal or aluminum gears, so they're great for high horsepower machines or the demanding rider that wants superior durability. With 14% bigger pins than the stock Rexnord chains, torque capacity and longevity is greatly increased by converting 2012-2015 models to the Borg Warner Hyvo chain and sprockets.

13 Wide - 34T Internal Spline Bottom Sprockets fit many 2016+ ProCross and ProClimb chassis 2-Stroke and 4-Stroke models. Compatible with only Borg Warner Hyvo Chains- see pic for link style. Some models use a 13 Wide bottom sprocket in conjunction with a 15 Wide chain and top sprocket- these bottom sprockets can be used in those applications.

Note:  2014+ 7000 models, and most 2016+ models use Borg-Warner Hyvo chain and sprockets- you cannot mix and match Rexnord/Link Belt/Silent and Borg-Warner/Hyvo Chains and Sprockets!  Models with OEM Rexnord Silent Chain and Sprockets may be switched to the stronger Borg Warner Hyvo Chain and Sprockets by installing the complete set. Please refer to the OEM parts diagram or open the chaincase to see what is installed on your machine before ordering- some models use the same chain and sprocket size top and bottom (ex. 13W Chain/13W Top/13W Bottom) and some may have an upsized chain and top sprocket (ex. 15W Chain/15W Top/13W Bottom).
