Does anyone know the rear spring rates for my 08 SP 800. I put Polaris HD front springs, it raised it about 1.5", now I would like to replace the rears to level it out.

 

I don't know, but I just changed out my front and rears on my sp800 with the EPI's. Glad I did, since it lifts them an inch or so.

 

I went with the EPI HD rears on my 08 800. Very good springs.

 

+1 for EPI springs. Replaced the stock front progressive rate springs on my '04 500HP ATP with EPI HD linear rate spings. Made a HUGE difference, cured the sag from brush guard and winch and some hard riding. Helped with the toe in, improved handling and steering at very little cost to ride quality.
Reasonably priced on top of everything else.
