There was a heavy duty air cleaner option on the 4X2 & 6X4 gators, if your gator has the heavy duty option installed this is not the right filter for you. You can determine if you have the heavy duty option by simply pulling your air filter out of the housing. If you have a single (1) air filter in the housing you have the regular duty air cleaner. If you have two air filters, an inner and outer ( One inside the other) then you have the heavy duty air cleaner and this item will not fit. We have the heavy duty air cleaners available, you can email us and we will list one for you.
