got the drive axel out of my race sled and figure I'm going to go to anti ratchets, would the 8 tooth be best for an ice drag application, im using a 9811 camoplast track.

thanks
 

If you are running a stock suspension the tips of the 9 tooth drivers will hit the cross member on the "W" arm, if you trim the tips approx 1/4" then they will clear the shaft.
-9 tooth extroverts are more effeicient then 8 tooth
-8 tooth extroverts do not hit the "W" arm x shaft and allow for longer lugs and/or studs
-you can just run the 2 extroverts on the drive shaft wich saves rotating mass
Some members have stated they just remove the outer stock drivers and just run the stock inner involute drivers instead of installing extroverts and then the driveshaft assembly is lighter then with the extroverts...I have not tried this...I would think you would need to run a fairly tight track to avoid ratcheting.??

Are you going for molded or CNC'd extroverts? I have ran both, and the CNC'd ones were far superior in my opinion. They are 100% true, and perfectly round.
 
You can run the extroverts by them selves, no need for any stock drivers on the axle. Boosted sleds (350hp) are running only the 2 extrovert drivers. I run 2" track delfection with no weight pulling the track down on a 162, and it will not ratchet.
 
true, most only use 2, definitely go with 9 tooth, less rolling resistance as stated = more speed. the only reason people go with 8 tooth is if they are going with a tall lug track, also when they do this it throws off your gearing so you have to regear the machine. if its your race sled you should be using a low profile track and alot of pics and have no need for doing it. have not tested myself but people i know say they actually lost speed for some reason with anti ratchets( dont know if i beleive it though) think they are still worth it though, im going to cause i ratchet really bad or have to have the track really tight and alot of drag.
 
^^^The 9811 is open/clipped every window.

First of all, what stud length do you plan on running...that will dictate what drivers you can use. Yes, you can run the two inner extro's by themselves.
 
Im using 192 woody's 1" chisels, and the suspension is stock just slammed to the ground (MRVIPER's method)

Just some info......if you are only running 1" chisels, you can run 10T involute drivers in that setup. It's what I would do. JMO.
 
if 10t has clearance yes. the bigger you can go and get away with it the better you are. going bigger wont ratchet as bad anyways, may not even need anti ratchets if you do that.
