Hello guys, I own a 2000 Polaris Sportsman 500 4x4. I bought it used and the suspension is quite soft. It's great for slow trail driving over rough terrain but it's terrible at high speed flat dirt roads when cornering. The body rolls badly and she squats low in rear when I punch throttle. I was trying to turn on a bend on a dirt road and had her on 3 wheels. LOL. I'm assuming the springs are to blame. The bike is 14 yrs old and suspension is original. Shocks and springs r expensive. Can I get away with just replacing the springs? I'm 6'-5" and weigh 200 and I double ride with my son or wife a lot. I was pondering buying some Heavy Duty rear springs. Any advice on brands u guys like or work better than others?
