hello all. I am in the process of installing a new 128 inch track x 1.75 252 pitch. i am not sure what to run for gears and am also wondering if i have to use extrovert drivers ? i was going to change the drivers right away but have been talked out of it by a fellow sled head that doesnt think it is necessary, i also understand that the stock gears in my sled are 21/38.i know gearing lower will lose some top end , but i dont want to lose a whole bunch. thanks to all responses and happy sledding !
run 22/48. that is what the cats come with that run the 129 inch 1.75. the 1.75 is a wind sail and will cause a lot of clutch heat issues if you do not drop the gearing
