buy it they are a great belt . I have been using them for yrs .
I have on on my 14M8000 took the stock off just after break in and put on the dayco.
u get a 1 yr warranty that is a lot better than the tail light warranty from cat.
I got 3 this fall only because I got a 45% off deal and know I will need them at some point in the next 4 yrs
