The turbos used HYVO gear sets not the standard rexnard (silent) setup.

Bottom gears can be found at recreation supply.

Top gears I am still trying to find whom may sell them.

If I remember correctly it is a 13w wide chain, NOT the standard 15w wide

Factory is 21/53. My thoughts are a 20/53 would be very good.

In the interest of this thread, here’s what’s inside. 20T top gear would be the smallest before you need to remove a link with all the slack.

This is my setup after 3000km, needless to say I was lacking some adjustment.

With the integrity of these factory tracks, I would go 22T or bigger.

Well I got 21-53 Hyvo gears in my sled. Can anybody tell me how this would compare too 19-49. Let’s say it is installed in 800 etec aerocharger turbo 7 pounds , which set up would be better in turbo.

You can put 19-53 in your gearcase and there is 2cm gap between each side of the chain with the stock chain used on the 21-53.
Full throttle there is only torque on the pull side.
Hand brake, there is only torque on the track drive sprocket shaft.
The only torque pushing on the adjuster slider shoe is "engine braking", "reverse" and slowing down with no engine braking, the inertia of the clutch shaft and portion of engine rotating assembly.
Not saying you have to gear lower, im only saying what fits with the stock chain.

Beware of 21 models~newer, the bottom gear is shaved on the backside. So if you tried to put a 2020 gear on the newer model, nope, wont fit, too thick, can't mount the c-clip. The 21~newer the track drive shaft is slight narrower (saving weight) than the older models.

Anyone in the DJ camp testing a 19/53 setup in the mountains. 2.78 ratio is aggressive but could yield surprisingly good results

Good Morn. Not really when on hard backed roads or trails want to be going at speed without being on to much boost. That when heat starts to come and motor gets hot.

Good day. I think I will go with bigger track sprockets. Make that turbo work when I need it. Over 3 ft. of white stuff where we ride.
