Polaris used to have FOX struts available for your machine. I have had 3 sets of them. The are the best addition to a sportsman you can do. The part # is 2872030. DO NOT get the 2872031's they are to long and will mess up the CV joints. The fox's are nitrogen filled, we used to put about 175 psi in them and would get about 1 1/2 to 2 inches o lift out of them and the ride quality is amazing.

Are you replacing the front and rear springs? Where are you getting them from? Let me know how the install goes on a newer bike. Thanks

Forgot to mention, I got my springs from Thor at theatvsupertore.com. EPI HD's on all 4 corners. He did right by me and I am very happy with my new springs. Gonna put them to their first real good test this weekend

I am going to do the fronts for now. I recently went up on the rear preload adjustments a couple notches in the rear, and it helped a bunch...I imagine when I do the HD front springs, i will likely have to increase the rear preload more (I am 6' 240). I will likely get the EPI ones from Thor...seems EPI makes the hi lifter ones, or so I have read...I assume they are all progressive springs (I hope so)?

My ATV was used mainly to plow before I bought it and my front was definitely sagging. I think the springs helped A LOT. I added the stiffer springs in the rear because of the Wes two-up seat I bought. I haven't had the ATV out yet but hope to get a ride in this month sometime. I bought everything through Thor as well and went to his house to pick it up since he is close.

I highly recommend you order both front and rear springs at the same time. The bike won't handle correctly if you dont.

I have the highlifter HD springs on my 2012. EPI does not make a kit for 2011+ value when I emailed them in January.

You likely got a good point there. I am honestly shocked at how much my fronts are sagging with only 250 ish miles on it. I ordered a winch today, so that will increase the front weight as well and only make it worse. I like to trail ride aggressively, and the front end pushing and diving in corners, especially under hard braking, is not good at all. So I take it you got Hi Lifter's all around on yours? Dont I have to order some spacers or something to make them work on my 2012??

Yes; trust me I tried it. It appears you ride like I do; you will be well pleased with HD springs all around. I have my rears turned up 1 click for riding aggressively; I'm 220 lbs. Would suggest 2 clicks for small jumping (1-2ft of air).

I also ordered front "moose pregressors" adjusters for about $60 for the front. That way if springs ever go weak i can turn them up without taking the bike apart. found them on amazon too

Amazon.com is cheapest for the springs, and they are from a third party! I looked for a while.

I ordered the adapters direct from Highlifter. SPRP-ADAPTER is the part number i believe.
