Hi all, I just got my first quad. 1998 sportsman 500! Lovin it, but the ride is really rough. The shocks only compress about 1inch or less with 225lbs bouncing on her. The shocks look older but the bright blue springs look much newer. I suspect maybe somone replaced the springs with HD springs. Shocks are adjusted to softest setting.

All I can find are $100-125 coil over replacements. I just dont have $500 to spend. Are there any aftermarket cheaper alternatives? does anyone know which years/models have interchangeable shocks/springs for my atv? Then maybe I could ebay some used parted out ones. I just need to soften this ride up alot for sport riding. Any other ideas??

Thanks guys

Did you check the preload adjustment on the rear shocks?

Bright blue springs...sounds like someone has put RZR springs on the back to haul a bunch of weight.
I've got a set of original 500 springs at the garage I'd take $25 for if you'll pay the shipping.
PM me if you want them and we'll work out the details.

Here's the springs Polaris lists as direct replacements. Mine are off a 2002. You might want to just buy the entire shock assembly off ebay if you don't want to replace only the springs. There's several listed starting at $30.

Thank you sooo much! That's just the info I need. You don't happen to have a link to the repair manual do you? I am going to check ebay and see whats out there. But I might go your route with the springs and the PM. Thanks for the offer :beerglass:

In those pictures you can see that the shocks are polaris, so im assuming all 4 are stock? You can also see how little they depress, theres only a inch of clean part on the stem. 2 of the pictures are the rear and 2 of the. From what I can tell, the front looks all front stock. And it is indeed softer. And you have got to be correct about the blue shocks. good thinking! so my shocks might have a good chance of still being good? I hope..

Looks to me like your rear shocks at least are toast. The oil on them indicates they are leaking and may be locked up. That might be the real problem.

Hmmm... it seems the case has just been reopened. Haha

it sure seemed like those springs had no give. And yet both rears compressed the same amount. They are indeed leaking, and could be seized. But the chances that they are equally bad. Makes me think it's still mostly the springs.

I guess I need to pull them and examine the shocks...

Thanks, now im not sure what to buy. Lol

Hi all, I just got my first quad. 1998 sportsman 500! Lovin it, but the ride is really rough.
Compared to what.... if this is your first quad? :gruebel:

I'd try....

1) Grease all the suspension & drive line zerks! :fing02:
2) Make sure the shock pre-load adjusters are set as 'low' as possible!! :D
3) Check tire pressures (just 1-2 psi can change the ride/traction/ect. immensely)!!! :wink1:

I've ridden 3 of my buddies quads. A 05 bruin, a 2 stroke polaris 300ex, and a 98 foreman. All of them especially the bruin rode like Cadillac compared to mine. Buddies rode mine and said I should invest in a back brace. Haha
Also II'm bouncing in and out of ruts and ditches. Suspension is not absorbing anything so I'm pogo sticking it... fun but not fun, u know?

1) thanks and your right! I will do this when I pull the shock.
2) that was done, still rough ride
3) was done also, no difference in this issue.

You might want to check the springs. I put HD springs on mine because I'm 260lbs and the stock springs were too soft. Plus I haul 2 50lb bags of corn to the hunting stand on it. If you are not the original owner there may be a chance the springs are not stock.
