Difference between Challenger extreme track and stock Challenger from AC

[brodCatMan]

I dunno if this is a stupid question or not but i dont really understand the differece from a Challenger extreme track from the stock challenger my sled came with. just wondering if anybody could help me understand a little bit better... thanks

The extreme is stiffer, and it doesnt seem to wear out in one or two seasons like the regular challenger.

What sled do you have? Are you sure its a challenger and not an Attack 20?

the extreme is a 2.5 and the stock cat is a 2.25 (i think),

Differences

As stated above, the Exteme is 2.5", the stock challenger is 2.25". The Extreme is slightly stiffer in the base of the lug (more material, heavier then the stock 2.25"). Finally, the Extreme is a night and day difference on the sled - worlds better then the stock challenger in most every snow condition, but takes a bit more grunt to turn it. Makes the M-series a much better sled IMHO.
