Get the tracks usa rail ext, gade thrashers yunnel extension, and get ahold of Bruce at CBperformanceparts.com or Rich at richmotorsports.com. You will save a chunck over buying a kit. It is an easy install. Maxdlx

I'm doing this to my 05 Vector, TracksUSA Rail Extensions, 1.5" 136x1.5" Ripsaw, HartmanInc Tunel Extension. Deciding if I should change to Extrovert Drivers. Any experience with them and what Size 8 tooth or 9 tooth. What is standard size on Vector 8 or 9?

I did my Nytro with 9-tooth Skidoo extroverts. 9-tooth is standard.

Whats the best way/tools to use to remove the driven sproket nut? I don't have the special tools they show to use. Drive Sprocket/jack Shaft Holder. What size is that nut, 38mm? Options not to have to buy the special tools. I think on my SRX, I used a pipe wrench and a pry bar in the secondary to hold it, but I don't want to do that again. Any ideas welcome. Thanks.

I use a big cresent wrench on all the 4 strokes.Don't put a pry bar in the secondary!
I use two pipes or big pry bars in the track windows and the nut comes loose easy.

pro116, I am assuming you have left the chain and axle sproket in place while doing this to hold it with the track? I have already removed them but can put them back on. I'll have to pickup a new wrench, didn't have an adjustable big enough. Luv buying new tools. Thanks.
