Anyone change the gearing from 19/50 to 21/49 and what results did you get?would like to get more track speed if possible.

I went to 8 tooth drivers on my '16, the driveshaft is a tight fit to install but it makes it. The sled performed better and keeps the engine loaded now. It nice on the trail now to with the extra gear. I believe the 8 tooth drivers added 10mph overall

you can, there is about 1/2"-3/4" clearance off the paddle tip. Its a tight fit getting the axle in...real tight

Do you think changing drivers is better than gearing up?

I did the 21/49 gearing change with a 3" track on a 14 m8 and achieved about 20+/- mph more track speed, originally I kept the 8 tooth drivers when the 3" track was put on but it was very tight and when it was colder than -10 c it packed with ice badly, rubbed a lot and made a hell of a racket not to mention gave a vibration type feeling and drove me nuts so I went to 7 tooth drivers and the gearing change. The gearing change gave me way more track speed than just the 8 tooth drivers and performed better IMO, loaded the motor way more. I should mention I was running a Speedwerx stage 2 kit as well. While doing the gearing change I beefed up the chain to the Hyvo one and went with the manual tensioner and Hyvo sprockets as well, no more aluminum

Anyone change the gearing from 19/50 to 21/49 and what results did you get?would like to get more track speed if possible.
