If you want to move the most snow, especially in the dry stuff... the PEAKS track... it is about 8 lbs heavier than stock in a 155"
If you want a lighter track.. I HIGHLY recommend the new style challenger extreme 9174 (153") or the 9176 (162")... You will need to switch drivers for that. See this thread,

With the peaks/ch-ext 2.5" lug track....Since it is a bit taller and you are moving more snow through the tunnel ... I strongly recommend going to a 7 tooth driver with the altered stock chaincase. See this Thread

Although for the most part they are "bolt on" tracks.... you can get better performance from them if you free up a little lug tip clearance.
