Rush suspension advice - Crazy ski lift

[Rushed]

I just bought a 2010 Rush and got my first chance to ride it yesterday. I had set the entire suspension back to stock since the previous owner was way smaller than me. I am about 210lbs and ride on the agressive side, mainly on trail. I am fine with some ski lift 3-4 inches? but I had scary inside ski lift of like 1 foot+ even my buddies in back were commenting on it.

Anyone on here about my size and have a basline for shock preload settings that will get me flatter cornering? sled has 84 studs up the middle and 6in Woodys carbides.

I'm going back up in a couple of weeks and would like to have the suspension closer so I can just fine tune to my liking instead of spending the whole weekend trying to figure out the sled.

Guess you didn't know about that with Rush? Where is limiter set? Rush is all about rider input not point & shoot sled you have to move around to get best handling. I was crusing behind early Rush with 1 hand on Yamaha Attak on Trail 17 south in Phelps & Rush ski lift was exactly what you said seemed dangerous so I backed off & this was at the end of 250 mile day for me. Attak point & shoot sled Rush wants you to ride it move forward for ski bite & if you are too far back skis will lift.

This was a common complaint with the 2010 Rush, crazy weight transfer. At the time the answer was slide as far inside and forward as you could to keep the front end planted. On the 2011 Polaris made a change to the rear skid to reduce ski lift/weight transfer and in both 2011/2012 they made tweaks to the front suspension. You might try searching some of the other forums to see what changes you can make, but that sled is inherently designed for max weight transfer....

one of the easiest things to try 1st is to tighten up the springs on the front of the sled=the outside ski spring tension is too soft in a corner allowing the sled to
"tip" easier. just did this on my new rmk 144 and made a big difference! easiest way to adjust is to tip sled on its side and have a buddy hold it while you adjust the one that doesnt have pressure on it

I should have been more help but early Rush do have ski lift just the way it is & what I have seen on the trail. I would soften the front rear suspension shock get more engine weight on front skis then play with rear shock until front starts to bottom on big hits then play between the 2 & at that point you will have to live with whatever ski lift you have & move around the sled when you ride. Like I said Rush not point & shoot sleds & depends on rider input by design. I'm too old for a sled like that & never was comfortable with seating position or exspending all that effort to ride.lol IMO Doo & Yamaha point & shoot sleds can't say about AC as have not been on their new sleds.

I appreciate the input but I'm really looking for actual Rush owners and specific setups they liked. Trying to get closer to right so I can spend more time riding than adjusting since snow time is at a premium this year with the crappy weather. I can take the time to figure it our but assumed someone here may be able to save me some adjusting time. I know about the Rush rider input and ski lift, that's why I bought it, Doos were getting boring...

My first thought was just like snakes and it actually seemed worse, it got better when I removed spring pressure on the front, this skid will take a little getting used to I guess.


My next thought is take the limiters up a half inch, take a 1/4 inch out of the FTS put a 1/4 inch into the RTS and then hopefully that's close enough to fine tune the IFS.

Delete this thread & repost for Rush owners only to reply & just let them know what year Rush you have & start over. Progressive Rush rear supension is different & you probably can improve ski lift somewhat but what you stated is exactly what I saw out there with 1st couple of year Rush. Reminded me of the great OEM ski lift wars of the late 90s early 2000s. Poo was supposed to make adjustments to decrease ski lift but not sure how well all that evolved. Poo seems to be going in direction of open rear end like new Indy as pro ride evolves. Good luck & let us know if you solved ski lift problem?

10 rush can be made to handle pretty good. I have ridden with 2 different 10s that corner good.

I have a 13 switchback that had to much transfer out of the box. Lots of ski lift, but not terrible in the middle of the corner, just on acceleration. What helped me a ton, lowered fts, didn't measure it, just lowered it a turn or so. I only have a few threads showing yet on the shock. I then turned up the clicker on the fts to prevent bottoming. About 4 turns IIRC. I also tightened the preload on the rear spring a bunch. I originally set it about 20-30 lbs lighter than my weight, per recommendations by a lot of others. I didn't measure what I turned into it, but it has to be at least my weight, maybe more. I plan on turning this up a little more yet. I originally turned the rear clicker up, but I may slowly bring it back down. I am getting pretty close, I won't have to adjust limiter, which is good. I also haven't played with the front suspension yet. Though I like a soft spring front end, I personally think the rear suspension plays a bigger part in ski lift/flat cornering than the front suspension does. But I will play around with the front on this sled to see what it does for it.

This is what has helped me so far anyway. I have read that the fts on the rushes have way to much preload from the factory. I would prolly look into that first.

Here is a youtube video from Polaris on setting up the 2010 Rush rear suspension http://www.youtube.com/watch?v=T26d_SJS1As

Or go to google.com and use the search phrase "how to setup rush 2010 rear suspension" and there are several discussions and links from SuperTrax, Hardcordsledder and others, along with the video listed above.

As mentioned in a couple of the posts here, getting the balance right between the front and rear track shocks, as well as the limiter straps, appears to be the solution.

Good luck.

This is actually adding pre-load and would make things worse. Loosen the springs until the spring is free and then hand tighten.

Another area to look would be the limiter straps. You could move up a hole to try and get more ski pressure. I am not a polaris guy, but maybe you can also get a beefier stabilizer/sway bar and/or softer front springs? Best thing to do with any suspension changes, is make them in small increments and keep adjusting. May have to dedicate an afternoon to just get a good baseline.

mnblizzard,I agree to a point,but it does depend on transfer in the rear suspension also.I should have specified,but you are correct in telling him to do small adjustments and to have patience in the process. BUT,the front spring preload can help to be stiffened,depending on how the rear is set up. I have adjusted many sleds in 38 years of riding,and my last few polaris' have benefited from tightening up the front spring preload,maybe the rush' are diff?I think alot of people get diff. results with their adjustments because of diff. rider input=weight,leaning,ect... but with my last few polaris'=all I had to do was stiffen the front ski springs and I loved it!!

Rushed...you gotta sell that junk and buy some black and yellow so u can keep up with me in a couple of weeks. At least until mine goes boom. Not to worry though I should be able to find replacement parts by march

You could go to "HCS" website (HARD CORE SLEDDERS) Then scroll down to the sub-forums.
It has all the info you would need for the Rush or any other make and model.

I ride a 2011 Rush ProR 800. I did adjust the springs on the the front shocks I believe one to two full turns which will help put more pressure on the skis and reduce the front end push. I have the rear shock set for my weight, but if you want less ski lift turn the collar clockwise as if you were setting it for a heavier weight of rider. Small adjustments in the rear shock collar will make noticeable changes to ski lift. I apologize, I do not recall how many clicks I am running on the clicker adjustments. I posted on this same topic when I first got my sled, if you can find that post there was a member that had a lot of helpful tips at that time.
