A new chain tensioner for the Razor Crazy Cart XL (Versions 1 ) electric go-kart is an important part of the drive system and should be replaced if damaged or lost. A faulty chain tensioner can be identified by a loose chain that falls off during ride time. The Razor Crazy Cart XL is a crazy little fun machine, but when you need a replacement tensioner it acts more like a malfunctioning little no-fun machine. If this minor tragedy occurs, aren't you glad that we are here for you?

Note: This chain tensioner is for the Razor Crazy Cart XL and is not compatible with the original Crazy Cart.

Model versions can be determined based on the product ID code on your Razor product. The product ID code can be found on the battery cover and/or on the bottom of the frame. The 7th and 8th numbers in your product ID code are the version number of your Razor product (e.g. "01" = Version 1, "02" = Version 2, etc.)
