I've got a 1996 model fourtrax 2wd. We've had it since it was new and we just replaced the factory Goodyear tires on it last week with some 25" interco swamp lite tires. The carbs been jetted, it has a small bracket lift in the front and haven't done the rear lift just yet. Other than that it stock. Me and my gf like to take it riding together. Combined weight of 400 or so pounds between the two of us. The rear sags down a lot when I sit on it myself let alone the both of us. Wanting to find a spring or a shock that will make the ride better and not sag as much. Thanks in advance guys!
