After a season of trying various set ups on my Pro S SB to get it to corner planted like my old Edge did I have become frustrated. 99% somewhat aggressive 250#(geared) trail rider. Trails only no ditch banging. I went from being the fastest in my group on my Edge to the slowest on this SB. The ride comfort is decent..handling sucks. All stock components so far. Ski shocks 1/4 " from loose 4th click,, FTS about 1 " clicker on 4, RTS according to conditions that day and clicker 4. 96 studs, 6 inch carbides. What do I need? Hygear springs? XCR set up? Whats the best bang for my buck to solve this? Thanks in advance...
 
For me, hitting on the ride and handling I was looking required ditching the front track spring with a 150lb. While it was a substantial improvement over stock, going with an XCR front track shock and spring combo got me all that plus I was finally able to reduce what I considered overly heavy steering effort. Sled is still in storage so I can't measure the preloads but I can tell you I kept cranking up the FTS preload until the front of the sled sits substantially higher vs what it did with the stock spring (it sacked out in very low miles). With sled higher your first thought (and mine), it must have hurt handling, nothing could be further from the truth. Sled feels dramatically more balanced, high siding in the corners, gone, heavy steering on rock hard trails, gone, front end comes up with a flick of the flipper all the while the front end bites with confidence under all conditions. While mine is a Rush, seeing what a buddy is going through with his Switch has me thinking the exact same applies to it as well. Will know for sure once the season fires off as we'll be applying the same to his as he in no way shape or form enjoys it as is and agrees mine feels dramatically different, in a good way.
Should you jump straight to an XCR shock / spring combo, for sure it's the best option but if I'd hung in with adjusting bigger spring on the stock shock, likely could have got it a bunch closer to the XCR stuff but for sure the XCR shock with it's dbl adjust ability is giving me the best overall ride.
 
Thanks ZR.. I really appreciate your response.. I am thinking your XCR set up maybe the right choice.. Its very noticeable that the XCR guys seem more satisfied with their suspension,ride and handling.. Even the media guys reflect on this a bit.. If you dont mind me asking what do you weigh with gear about.. Im wondering if my weight is making the front end feel mushy in the corners to me. Front springs overloaded? And if I must address this too. I have noticed that if I turn up the preload on my rear spring to where the sag and ride in are right for my weight,That the steering gets excessively heavy like you mentioned yours was before.. Thanks again
 
I'm low 220's plus gear.
Your post sounds all to much like what I went through, fix one thing but upset another. Thought I'd hit on something I liked several times only to have snow conditions change and the sweet spot not feel so sweet. When sled was in the dealer for crank seals over the summer, service guy asked whats up with how high I have the FTS cranked up, said it looked closer to what you'd expect from a Pro X.

You need to send all your shocks out. Hygear, monster ect. They will fix you up. Anyone 200+ the pro s just doesn't work good. Swapping springs is a band aide and not a really good fix as the shock valving will not match and it will pogo stick.

Also these sleds have no torsion springs, and adjusting the shocks slightly changes the dynamics greatly as the springs are what do all the work. I have had best results with polaris's recommended shock preloads. Bigger guys try to use shock preload to stiffen the shocks and this is a really bad Idea. The shock preload is meant to set the balance of the sled not the shock stiffness. If you send your shock out and get it set up for your specifications then you will be much happier.

as far as an XCR setup. The XCR setup is still a one size fits all set up. I think you will be much better off to get your current shocks set up for you. The shock are not bad just the valving and springs are not right for you personally. If you give the shock company your specs they will come back custom for you. The only shock I would recommend is the XCR front track shock. It is a bigger body shock. The design of these sleds pounds the front track shock and it helps having a beefier front track shock.

could you describe more what issues you are having with the handling? You can not ride these newer sleds like the old ones. They are not sit down and stick your knee out sleds. You got to stand and lean.

What ^^^ he said. I had a 2016 SB and sent out my FTS and RTS to HyGear. I go about 240lbs so they recommended a stiffer RTS spring and I got their twisted spring for the FTS. They revalved both shocks to my weight and riding style and they were right on the money. I left the IFS stock and usually ran them at 4 clicks. If you feel the front squishy or dipping when cornering (like it did) then what I did was just go up a click or two which seemed to do the trick.
 
I have a similar issue. The ride is ok but sucks in the corners. I did the 150lb fts and 130 rts. They helped but still wasn't happy. I purchased the xcr fts and sent everything out to monster to have them revalved for my weight and riding style. They also recommend dual rate springs for the front. Now I just need some snow so I can get them dialed in. Hope it was money well spent.
 
2017 Rush Pro S ... I picked up a complete used set of XCR Shocks and it was like I bought a new sled. The spring rates are better and way more adjustability. Just Having low compression adjustability on front shocks is amazing. Snow conditions creating more body roll up front. Add 1-2 clicks firmer and bam on rails again. Conditions firm up and you start getting ski lift take the clicks away. If you ride hard and where you ride is rutted up bs You won’t regret it. Best decision I made.
Ditch the stock skis as well. I ditched the Pro steers and added set of Polaris Grippers. Went from some push to no push with have the rear spring pressure.
Wish I’d disregarded the salesman’s bs and just bought an XCR from the start. Live and Learn
 
Odd man out when I say I disagree with dual rate for the FTS.

I love the XCR shocks from a PRO-S to XCR upgrade is about $ 550. well worth the money.
