So I had bought the 2 inch lift, and there's a difference between the sport an trail model. The shocks are different sizes, fox 2.0 on the sport regular fox shocks on the trail. They give you spacers for the back, which I don't understand, it would just make the rear end more stiff. In my eyes, the shock can only extendy so far till it's maxed out putting a spacer in there to make the spring more compressed isn't going to lift it . It's just going to make the ride more bumpy.. I would think you would need a spacer In between were the shock mounts to the gator. Makeing the shock two inches lower from it's actual place would then give the machine a two inch lift, without putting a load on the springs..
