2011 500 HO rear spring/shock

My rear ends arms are sitting almost level at rest without anyone on it. When i"m on it, its feels as though the rear is sitting lower then the front and sinks easily while riding. I adjusted the preload but that didn't help. I also picked up a 2" lift kit but havent installed it yet. thinking i need new springs but was wondering if anybody knew of a longer shock that i could use instead of the lift kit?

Shocks don't have anything to do with ride height. Get some EPI HD springs if you need more in the rear.

The lift kit adds 2" to the length of the shock. HD springs will stiffen the ride. i am assuming the springs on mine are just weak. i have 5K on the bike.

Ok, If you don't want to replace the fatigued sagging springs I guess you can put on the lift. There might be longer shocks from some other machine you could put on and make work but I wouldn't know what they would be. Touring or x2 shocks/springs are probably stiffer but I don't think they're any longer..

Link that lift!!! I doupt it requires longer shocks!!! Either EPI or Highlifter springs are the way to go. FYI HL has the higher spring rate out if the two.

i think you guys are missing the point. i also picked up a lift kit as i want an all around 2" lift but i also have what appears to be weak springs in the back. i need to replace the springs to fix that or i was thinking if theres a shock that was about 2" longer i could use those to solve 2 issues, the weak springs and i would only need the stabilizer extensions from the lift kit for the rear making a cleaner install. I picked up a spring compressor and going to pull the shocks out and check everything over when i head up to the cottage in a couple of days

My daughter has a 2012 500HO 2up touring and those springs are stiff, the ride reminded me of my solid axle honda lol. the springs are thicker but i will have to check the length and mounting width on them. the ride on mine is great, super soft lol.

Well, if you already have the OEM springs cranked up to the highest preload setting and it still squats too much, you can put EPI HD springs on and set them on the lowest preload setting and it'll be barely stiffer than what you have now but they won't squat as much because they're a little stiffer spring. That's what I did on my 06 800 and loved it. I have no personal experience with HighLifter springs but I'm told they are substantially stiffer unlike the EPIs. Everything is a trade-off. You can't get less squat without having a little bit stiffer ride. It don't work that way unless you want to go with high-end suspension components. You can bust out a few thousand dollars for custom shocks and get them set up however you want!
Polaris advertises the soft cushy ride as a big marketing point for their machines. The OEM springs are on the light side to start with and they ship the machines set to the lowest preload setting to make them as soft as possible. With a little age the already weak springs get tired and the preload needs cranked up but that can only do so much. The answer is a little heavier spring.
