Keep finding it hard to pull trigger on new Cats when all parts from 12 to 21 are mostly interchangeable. I have a 13 800 Limited I got brand new in spring of 13 for ridiculous cheap. With all the mods I have done over the years I am still under the price of a new Alpha inc what I initially paid for sled. Currently has a 175 Camso 280 with Alpha drivers, modified rear skid with custom IceAge rails and Promotion. Vanamburg 174 tunnel kit, Modded 38" front with Evols, Zbros uppers and 2020 Riot spindles (1.5" longer). Did the guage upgrade from another member here and have A/F and all temp readings on factory guage. Also did C3 belt drive. Have a BD turbo kit I bought used that will be on soon. I wanted to try the track setup by itself against a N/A Alpha to see how it performs side by side before I turbo it. Clutching setup is the 2018 Primary and Secondary. Love this sled and how it handles for me and next upgrade wont be till second year of next big chassis change at Arctic Cat. I have always bought a new Cat every time there is a major chassis change since 1996 and usually the most radical or biggest sled they had at the time.
