Billet Aluminum Drive Sprockets (120s)

  • Olson Brother's precision machined billet aluminum sprockets are ultra light while maintaining strength and long life.

  • We start with light-weight, high-grade aluminum and machine each sprocket to perfection.

  • While almost all our competitors have Chinese stamped sprockets that are typically warped and have non-chamfered teeth that break chain, our sprockets are machined from solid aluminum bar stock to make a perfect sprocket that runs completely true with no wobble and guides the chain onto the teeth without chain binding..

  • For use on all 120cc sleds; #35 or #420/41 chain.

  • Note: All of these sprockets require Olson Brother's billet aluminum sprocket hub.

Aluminum Drive Sprocket, #35        $29.95

Drive Chain ( Kitty Cats )


  • Several times stronger than standard #35 chain.

     * When buying by the link, enter desired number of links in quantity field in shopping cart. Each large and small link counts as separate links. The easiest way to count the number of links you need is to count the holes in the chain where the teeth of the sprocket go and make sure you count the hole for the master link or your chain will be too short.
