A new chain tensioner for the Razor Crazy Cart electric ride-on 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 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, our easy to install Crazy Cart chain tensioner will get it up and running like new.

Note: This tensioner is for the Crazy Cart Versions 1 - 4 only.

  • This tensioner is for the Crazy Cart Versions 1 - 5 only
  • Chain tensioner includes the spring & the roller
  • Doing your own simple repairs is an economical way to keep your Crazy Cart running like new
  • Note: 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.)
  • Manufacturer Part Number - W25143499079 / W25143490079
