So, I've got the 850 working well and now it's time to focus on old faithfull - my '03 500SP. I'm looking for opinions on front suspension springs. When the quad was less than 1 year old, the original springs were sagging badly. I had read (at the time - '03) that people were running the 700SP springs in the 500 with good success, however, my dealer at the time talked me into going with Ranger springs - telling me that lots of guys were going that way and the heavy springs would soften up in a short period of time. Well, it's been seven years now and the ride is still way too stiff. What are others running ? Are there adjustable conversion kits available ? (I'm sure I've seen them before).

 

do a search as theres dozens of post on the fornt springs and ideas for you.

 

Polaris sells a hd front spring or you can check the sticky on spacers. Elka makes an adjustable shock but you will need to rob a bank to buy them.

 

Look into Erlandson Performance, EPI, they make a progressive rate spring, soft on the top and gets progressively stiffer towards the bottom, I had them on my 03-700 and loved the ride, around $100 bucks for the front.

 

Polaris when from a 6.25" travel suspension to a taller 9.5" .hope they did not compress the taller spring on,that would be a stiff ride.

 

Thanks for the replies. I think the EPI's should fit the bill. It's a little hard to justify Elkas on a 7 1/2 yr old unit.

 

I just bought the Polaris HD springs,seem to work good enough,$70 at the dealership.

 

I don't think the '03 500 had progressive rate springs. Those were in the 600 and 700 only. It also looks to me for that year in the 500 the spring rate was lower then any other year which would help explain the increased sag. I have the EPI's and they are great but for me I have a 600 and it does have the progressive rate springs.
