This is our replacement chain tensioner is only for the Razor E300, versions 36 and up. It is unique to that scooter. Because the tensioner's spring is often lost or broken we have included an extra spring for you to keep as a spare. This means that your tensioner will come with two springs.
Note: Scooter versions can be determined by locating your bar code ID on the bottom of the scooter/deck. The 7th and 8th digit in the series will tell you the version of your product: 01=version 1; 02=version 2; 09=version 9, and so on.
