I also bought the High Lifter 2" and added the RacerTech medium springs. Quite happy, although I just bought new shock/springs for it to upgrade the stock shocks. I ran with the extenders on the sway bars, then took off the sway bars (front only). Have decided to run that way as I'm not a speed demon on the corners anyway. I believe, though may be incorrect, that the shock preload only raises your ride height. However, it does compress the spring, so probably stiffens the ride a bit. I have read that all four preloads should be the same.

Some of the faster riders will have to answer your other questions.

 

I installed the medium racer tech springs with 2 inch lift kit this week. I left the front and rear sway bars disconnected. I haven't had the chance to try it yet. I'm a little nervous reading about body roll from people that have left the bars disconnected. I'm considering connecting the rear sways for a little stability although some people have said that they would never go back to the sway bars and haven't had any problems. Most of the riding we do is less than 20 mph on tight trails with ruts and rocks but some riding up north is fast logging roads with sweeping turns. I wish there was an easy quick connect option. Any more advice from riders with more experience?

 

RacerTech has a quick connect option for the 800 that should easily be modified or reverse engineered for the 570.

I don't know how it is with a lift but I took mine out last night for the first time since removing the front sway bar and I don't think I will be putting it back on. I put 30mm spacers on all 4 wheels at the same time so maybe the extra couple inches of width helped. I was already at 2 clicks on the preload and I didn't adjust it any.

Prior to testing it in the desert I was worried because all of the body roll I felt on pavement. After some pretty sharp turns at speed and some doughnuts with the pedal to the floor from a slow start I never thought I was going to go over. My passenger felt nervous though.

Give it a ride before deciding to do anything about it if you are just going off pavement experience. It might be fine as is.

 

After the lift install, my rear sway was easily re-connected with the Rzr still up on the floor jack and the suspension arms at full droop. Just had a second pair of hands to help reconnect the opposite side I was connecting.

 

X2. To make it a bit easier just drop it off the jackstands. The rear bar has plenty of travel. Where extension is needed is the front IF you plan to use them. Not needed unless you like hi-speed turns without a lot of lean...

 

Anyone using the SuperATV springs? Being budget minded, seems like the SuperATV's are the cheapest. Just wondering how they perform vs Racer Tech or UTV's?

 

Wanna bump this thread back up.....

Recommendations for higher speed stability after 2" High Lifter lift kit and front sway disconnect?

Still looking at wheel spacers to get width to 50-52" and medium or HD springs?

 

Give the front preload another click or two and see how it feels. It should stiffen up the front a bit and give you an idea of what a stiffer spring might feel like.

You could try the front shocks from a 450 Suzuku/Honda/Kawasaki for pretty cheap. They have stiffer springs with more travel and adjustability than the Sachs shocks. Check out the thread on them in the suspension forum. Ignore the info on the rear shocks because they don't work with he 570.

 

I'm slowly ( money tight) setting mine up as follows. I will be running a racetech 2" lift, stock shocks with upgraded springs, no sway bars, 1.5" wheel spacers, 14" rims with 26" tires. One day upgrade shocks.....I hope this will give me a nice ride for the open trails and fields. On a 2011 800S.

 

Well....I decided to re-attach the rear sway bar after worrying about having excessive body roll. What a pain in the butt! I ended up having to trim up the bushings despite all my best efforts not to. I may try to extend the rear sway links and then use the un-altered bushings from the front sway links. I'm not sure if I like how tight I had to pull down the suspension to re-attach the rear sway. I'll get a chance to try the lift kit and medium racer tech springs for the first time this weekend. Should I keep the medium springs at the softest preload for now or should I adjust them a notch or 2?

 

I don't understand why you had trouble reconnecting the rear unless 1: it was still on jacks or 2: you accidentally switched the front and rear sway links. Mine connect and disconnect quite easily. The rear sway links should measure about 15 1/2 inches from shock mount hole center to the end of the link.

Wait a minute. The RT lift kit installs at the top of the shock, doesn't it? The HighLifter kit installs at the bottom of the shock, meaning no extension of the sway link is needed. You may need to extend your sway link with a pair of coupling nuts and two pieces of 10mm threaded rod, or (as someone else here has done with great success) move the rear links to the front, have the front links cut and a 4 inch extension welded in, then installed on the rear.

Whoever did that mod, please chime in with a link to your thread & pix?

Steve (Forgiven), can you post a pic of the coupling nut/threaded rod mod?

 

To recap the previous suspension setup: stock shocks and springs, stock LE tires and wheels, 2" High Lifter lift. Update after latest changes: Installed 30mm spacers on all four corners and adjusted the spring preload to the fourth position on all four corners with the stock shock/ spring. The high speed stability was much better. The turn-in was quick, just needed to be careful on pavement. No understeer on gravel or the dirt with this setup; the steering was much improved.

This setup cured the understeer on all surfaces and the excessive body roll. Still looking to add a set of HD springs and get new tires.

 

Finally had the chance to try out my setup this weekend. I have the RT lift kit with RT medium springs. I re-attached the rear sway bar with the included spacers. I rode 125 miles on mostly faster old railroad beds( The Sunrise trail in downeast Maine). There were a lot of wide sweeping turns at speeds of 40-50 mph. There was no feeling of instability and I didn't feel the front end diving at all either. I am definitely leaving the front sways disconnected. I plan on using Soapy's method of adding some length to the rear sway bar links as I think that this may free up the rear suspension a little more without completely removing the rear sway. This would also make removing the rear sway bar easier and make it less difficult to re-attach should I not like the feel of the ride with no sway bars attached(which I would like to try soon). Still experimenting....

 

Definetly wanting to extend the front sway bar and put it on the rear suspension like Soapy.

 

I just ordered a Highlifter 2'' kit because I'm going to do some rocky trails in a couple of weeks, so I went and measured my ground clearance. With stock shocks, RT medium springs and 26" Duro tires, I had 11" in the front and only 9" in the back with the preload at the lowest settings. I already have 2" spacers for the stock 2+6 wheels so am sitting at 54" now. I may only put the lift on the back and adjust the preload on the front to get better clearance but I always worry about stability on these steep trails so I don't want to get carried away. I'll let you know how things work!

 

To continue my previous post, I started at the rear and installed the Highlifter kit. Not as easy as expected. Had to remove the clamp retaining the brake line and grind down some welds on the lower a-arm to get proper fit. Not using sway bars, so no issue there.

But, as I attempted to install the front lifts, I find out my steering links are not long enough to accomodate the extra distance with the lift. So I did not install it and just adjusted the preload of the front springs all the way up and measured everything after a short test ride. 11 3/4 at the front of the skid pan and 10 1/2 at the back with the preload all the way down. Will probably lose a quarter inch in the back when I put my tool box in but I think this combo will work. If I put the lift in the front I think it will raise the front to much affecting handling. Going to give it a good test tomorrow and let you know how it works!

 

I am also looking into adding the Highlifter 2 in kit to my 2012 570. I noticed on the site that this kit is for a 2012 model. Is there a difference in the suspension setup on 2013 model? I am looking into getting anther RZR and was wondering if there is that much difference year to year? Maybe this is why some are having troubles installing the kit. Just wondering....

 

After testing my lift on a good variety of trails, I'm pretty pleased with the results. The ride is not much different but I think the rear is working better, perhaps because the shock angle is a little different giving me slightly more travel and a little softer ride. But in this particular creek crossing where I always bottom out and hit the skid........not this time. The extra 1 1/2 made a difference. Not much difference in cornering except on really sharp, fast turns it was a tad more tippy. No worries, I'll adjust for that. I doing some major rock trails next week so I may up the preload on the rear for more clearance. Should be fun!

 

Jaymanwv, it fits the 2013 exactly the same as the 2012 with no problems. I installed the highlifter 2" lift and medium RacerTech springs on my 2013 and it rides much better over rough and rocky trails and gives you a couple more inches of ground clearance.
