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.

Deluxe Chain Tensioner

• This chain tensioner is 5" long, 2.2" wide, and 1.7" thick including the roller and bolt. The aluminum plate can be mounted anywhere on the tunnel you choose to place it and it mounted with either two 1/4" bolts or four 3/16" rivets, the choice is yours. Although sprockets are much cheaper to use, we have choosen to use a high quality roller that's 15/16" wide so it's very forgiving no matter where your chain is running and it's one less sprocket you have to shim to be in alignment with the clutch and driven sprockets. The roller has nearly 3" of travel to tension the chain to your preference and is very quickly adjusted.
