i want to put a 2 inch track on my nytro and 8 tooth wall bro drivers what kind of gearing do I have to do switching to 8 tooth drivers and is there any other mods I have to do to pull this off other than taking out the tunnel protectors?
 

i recently changed my track to the 1.75 bc. While doing it i put on a 19/39 top gear, changed drive axle bearing(clutch side), fixed limiter straps, and greased all the skid nipples. If i were you id do the same. The smaller top gear will make for better acceleration but lowers top end speed. which doesnt really matter since it'll still be like 150km/h and your off trail riding anyway.
 
Do you still have 9 tooth drivers? And what happened to your limiter straps I broke one awhile back not sure why.
 
The 08 shaft is not the same size as the 12 but thanks.
 
I did what u r wanting to do. I did the 2" track and went with 8 tooth drivers. I already had a clutch from Ulmer so he swapped me for a diff helix. He told me that by drooping a tooth I did not need to regear cause the smaller drivers do it automatically. In a week I will know how it does when I hit Albany, Wy
 
Thanks I decided to just go with a 1.75 and keep the 9t drivers like thekoning did.

What kind of clutch kit do you have or you still have the stock clutch ?
