After reading so much on here about riders putting HD springs on their rides, I figured I'd try something a little different and a little cost affective. The one thing I don't like about EPI's front HD spring is that its not a progressive rate spring like the OEM springs that come on all Sportsmans. While this will make it more stable and gives it a little bit more lift, the HD springs ultimately give it a firmer, stiffer ride. Which personally I don't like on a utility atv. Now the OEM front springs on the 500s are too soft and start to fade after a period of time. The springs have a progressive rate of 52-90lbs. So what I did instead of HD springs, I put a set of Sportsman 800 springs, which have a rate of 75-111 lbs. They are basically the same length as the stock 500 springs, but with a 20lb higher rate. And believe it or not it makes a difference. It rides a lot better, handles better, sits up just a tad bit more and it makes the atv sit level. Plus it does not fade as bad either.
On the rear shocks, I put a pair of 1" spacers on my wore out springs. While this is probably not as good as the HD springs, its a good, cheap alternative. It still has that famous Polaris IRS ride, but without all of that squatting it did before. Plus it has a little bit more sportier feel to it also.
I did all of this for under $140. Appearance wise, it does not have that look where the front end is sticking up higher than the rear end, like so many I have seen with the HD spring setup.
I'm not bashing the HD spring setup at all. I'm just giving the 500 guys another alternative thats affordable and works pretty well.
