I'm upgrading my track from the stock 2.25 to either a 2.6 from a 2013 or a 3" challenger extreme. Will the 3" track fit? What mods if not? Cons to a 3"? Gearing? Running a BD pg turbo. Any help greatly apritiated.
3" track on 2010 m8 questions...
- Thread starter Catscanfly
- Start date
Catscanfly, I was wondering the same thing. I haven't ridden mine yet with the 2.6" Powerclaw but, I will say it was a tight fit getting the track back on the driveshaft with the driveshaft merely loosened up and hanging there. I guess if the track doesn't hit the tunnel when its spinning you will be alright.
However, I do have to wonder if at some point the volume of snow being shoved between the tunnel and the track above and forward of the drive shaft. As the drivers rotate and compress this snow, could this choke point pose a clogging/clearance issue with such large tracks? I am thinking this is where a nice mild track porting job may help remedy such a problem by giving that snow and air being compressed in this small area another place to go.

I'd like to go with the three inch if I can. I've heard cutting the lower 3 fins on the heat exchanger makes this possible. I've also heard I'm going to run into clearance problems with the diamond drive. Keeping the stock drivers would be a bonus as I wouldn't have to immediately change the gearing in it. It would be nice to run what I have for a bit and make adjustments as needed. I'd like to stay away from porting.
Thanks for your input.

The 3" will fit with some cutting to the track. If you get the 16 wide you will have to cut it down to 15 wide, notch the outer lugs on the top outside corners to clear the cooler lines, cut the lugs off the inside and trim the clips on the dd side to clear. There's the new 15 wide out now too but I think the 16 wide cut down would work better. You won't need to notch the cooler at all. It's tight but I've never had any issues with rubbing or snow clearing. The 3" is very well worth it
The reason for trimming the bottom three fins off of the cooler is for clearence. Yes it will fit with no modifications, but it is very tight. The more clearence you have the better. I also had an 1/8" machined off of my driver's for a little extra clearence. I could have went to the seven tooth driver's, but I wanted to keep the drivers as big as possible. Just my opinion!
