New challenger extreme vs old?

[snowmanx]

So whats the big difference and does anyone know if it works as well? They still have the 9175 part number, is that still the old one?

Thanks

The 9175 is the new style. 9943M is the old. From what ive heard the old is a harder rubber then the new, not sure if that is actually true. Also the new lug is flat across the end, the old had tiny fingers.

X2 the 9175 is the new one which funnels snow towards the center

for better flotation

I know the old style 9943/9944 are incredibly tough and durable tracks. The new style 9175 is single ply i havent heard how well they hold up.

The PEAK reminds me of the yamahas I saw at the sneak peek last spring.

The PEAK reminds me of the yamahas I saw at the sneak peek last spring.

I believe it is a very similar track, but in a 2.25" lug version, not a 2.5" version, and it is called the Ascent, not the Peak. I guess that makes sense since it is shorter?
