Default '06 SP500HO EPI Heavy Duty Springs Installed

I've had these springs for 5 weeks now and have been trying to get a hold of some spring compressors so I could do the install. Thanks to some other members and information from other ATV forums, I came upon instructions to do this job without compressors. I removed my stock springs today and installed the EPI springs.

With the stock springs, the ATV had 3 inches of sag easily, and that was without any weight at all on the front. Add to that the weight of my Moose plow and the front end dive was a sad sight. With the EPI springs, front end sag is 1 inch if that. I didn't get a chance to put the plow on, but just pushing down on the front end with my own weight was enough to feel how much stiffer these springs are.

Now all I need is some snow to push around! I'm sure these springs will work great for plowing, but I haven't been on the trail with them, where I have a feeling they might be a little harsh. If I get a chance, I'll take it out for a ride in the coming days to get a feel for them. If they turn out to be too stiff for normal riding, I'll probably order a set of the preload adjusters and install them next Spring/Summer.

Thanks to everyone for their daily input in these various threads. As much as I hate to waste money and go to the dealer, I'm glad I could do this job myself and without the added expense of specialty tools. CLICK HERE for a few pics of the install.

Thanks for posting the pics! Stupid question, did you just replace the springs on the front? Did you do the back as well? Do you plan on it?

I have no sag on front or rear. It is still a little too cushy for me on the rear. I have the adjusters all the way up in the rear and I have 800 rear springs on the front of mine! The only sag I have is from tire sidewall flexxing, and I love it!

I only did the front and only for snowplowing. The rear is fine because it has preload adjusters.

if you look at the back springs you will see that it has notches on the bottom that you can use a spanner wrench to adjust them for stiffer or softer adjustments.

You didn't need to use a spring compressor to remove the front springs. Once the weight of the machine is off the suspension there's almost no tension on the springs.

I swapped out the stock front springs on my X2 and gained 2". The ride is a little harsher but it's no big deal.

Why not just use the rubber sprin? spacers from Polaris? I use those on my sportsman and they seem to do the trick. If I want a nice cushy soft ride, I just pull them out.

I ordered mine directly from EPI www.erlandsonperformance.com sort of pricey.
