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.

you desire by interchanging these clutch sprockets.

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.

Deluxe Replacement Roller
- This is the roller used on the Deluxe Chain Tensioner. Although we've never had to sell a replacement yet, they are available if a roller ever wears out.

Deluxe Roller Kit
- This kit allows a person who has the standard chain tensioner to upgrade to the deluxe model. The kit contains the roller, bushing, carriage bolt, washer and lock nut.

Polaris Skid Wheel Kit
- This kit lifts the track away from the slide rails slightly to remove some friction and allows the track to spin more freely.
- These kits contains wheels and all mounting hardware.
- More than 80% of the friction comes from the front of the slide rail where most of the pressure is applied, and therefore we sell our kits with either two wheels for 1/2 the price or the full four wheel kit if you're racing grass drags or just want the extra support.

Drive Chain (120s &
Kitty Cats)
#420/41 GOLD RACE CHAIN
-
Our gold chain is made from lightweight
Chromalloy steel construction with seamless rollers and
bushings, then heat treated to produce an even stronger
chain. This is the strongest #420 chain on the market today
with a wear index of 300 and tensile strength of 5000.
-
Works great on all 120s, but a must have for the Arctic Cat Z-120 where chain heat from the exhaust is a major issue.
-
Available by the length, which is a
minimum of 4' (100 links) depending on what our distributor has available. The price remains the same for all lengths.
#420/41 STANDARD CHAIN
* Enter desired length in quantity field in shopping cart.
#35 SPACE CHAIN
- 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.
#35 EK SILVER PRO CHAIN
-
EK chain combines the qualities of high
tensile strength, low wear, impact resistance, anti-kinking
performance and fatigue toughness to produce the best kart
racing chain available..
-
Available in box of 40" (106 links).
-
Pins are Chromium Carbide coated offering
superior impact and shock absorption and reducing oxidation.
#35 HIGH TENSILE RACE CHAIN
-
An EK chain that is manufactured to be the
highest strength and most wear resistant #35 chain anywhere.
Much stronger than standard space chain or Silver Pro chain.
This is the premium #35 chain of all.
-

snowmobiles, but engineer for high torque applications.
Ideal for F1 and Champ class racers.
-
Available in box of 40" (106 links).
-
NOTE: This chain is a complete and continuous 106
link masterless chain with no master link. If you'd like me to
make a masterless chain for you to a special length, please text message, email
or call me before ordering wtih the number of links you'll need. Otherwise, you can use a Silver Pro master link, but it will be the weakest link in the chain.
#35 STANDARD RACE CHAIN
