what are the stock springs in the rear suspension? what springs can i get that are stiffer as i ride 2-up most rides.

ProX Man

Could you be a little more specific about the sled you need new torsion springs for???? I can't quite tell if it is a ProX or an RMK. There are lots of torsion spring options for either sled even springs specifically made for 2-up riding that could be the solution to your problem.

on a prox probably want .405 for 2 up unless both riders are light. then you are looking at .375

where would you find these springs? my son has long tracked a 2002 prox 600 . want heavier rear springs to stop the sag and compensate for the extra rail length

the sled is a 2002 prox 600. has been lontracked toa 136 usa kit. would like heavier springs to compensate for sag and rail length

my sled is a pro x with 900 cat motor in it. longtracked to 136 with full polaris rails, and im on the heavier side and the gf is average 17y/o girl weight. Whats the stock spring size and what are my options for stiffer. also would i want the 77 degree square, or the 90 degree square?

DANZ123, all pro x's have the suspension sag. if you want to get rid of it, every season you need to pull the rear suspension and grease up EVERYTHING. all the zerk fittings, and the bushings also. Those are what stick and makes it have that little bit of sag.

Ok

So I am going to assume you have an '03 ProX trail chassis. Here are the springs available for that chassis with the Polaris part #'s. Same springs fit the ProX racer, stock on the '03 racer was .347.

7042101-067 Spring, Torsion, .347 PRO X/77, LH [Std.]
7042102-067 Spring, Torsion, .347 PRO X/77, RH [Std.]
7042157-067 Spring, Torsion, .359/77, LH [Opt.]
7042158-067 Spring, Torsion, .359/77, RH [Opt.]
7041631-067 Spring, Torsion, .375/77, Firm, LH [Opt.]
7041632-067 Spring, Torsion, .375/77, Firm, RH [Opt.]

Also here is a spring available for 2 up riding, it is optional on the 2 up touring sleds and will fit your ProX

7042240-067 Spring, Torsion, .405/77, LH
7042241-067 Spring, Torsion, .405/77, RH

If you decide you need the stiffest springs you should also consider replacing your front shock springs as well, they are likely sacked out unless they are new already. IMO the front track shock spring is likely still in fairly good shape, we seldom see those wear out near as fast as all the others.

Retail price on these torsion springs is around $70 each, but it's worth the cost. You may be able to get a better deal from your dealer if you know what you want and bring him the part # when you go to the parts counter.

Hope this helps

i just checked the polaris site and its $76 for both left and right hand sides, pair. do i want the 77* angle ones, or the 90* angles

also when i ride solo, i ride hard. should i meet somewhere in the middle with the springs? what would happen if i get the big ones and ride by myself, harsh ride?

you want 77 degree. depending if you are under 200 and ride solo with the 375 springs it will ride rough

Prox man I was going to give you a hard time but the more I think about it ..... I will cut you some slack! I rode with a set of 77* .405" on my xc 800 , even with the wimpy shocks that come on a xc those springs will rattle your filling out .... I weight 235 without gear and ride like a seventeen year old . So my point is you can try the .405 , they are cheap but in the end if your GF likes the sport get her off the back of your sled so you can ride! Buy her a xc 500 ~ 600 thats a 2001 or newer , its better then get hit off the head every time your going to fast for her! New cat 900 under the hood , come on dude riding two up..... wrong sled

$76 for BOTH the left and right side?? When I priced them my dealer told me they were $70 EACH. $140 total. Did I get bad info? :frech32: I wouldn't doubt it if I got bad info. Every time I'm there they give me that "WTF look" when I tell them I have a Pro-X like they've never heard of one. I need a new dealer, but they're the only one within 200 miles. :banghead: :banghead:

you buy a pair online form pure polaris and they are half of the dealer price. Maybe the dealer can give you the pair price as well but I am sure most are not smart enough or interested enough to look it up that way. The link you are after is http://www.purepolaris.com/Detail.aspx?Ite...ge=2&nSet=1

Last year all of these were available on the web now they say check with the dealer. Hopefully they aren't running out.

I am sure your dealer is just trying to make as much money off the part counter as they can! THey are not the same part number getting it in a kit as buying off the parts locator. If your dealer opened the polaris pure book they could have had the same price!

xc mark, what springs did you like then with your weight? the 375 or 359's? i know, she likes the sport, i just dont have money at 18 to buy her a sled, expecially when in college. try to get out 3-4 times a week, and shes usually with on 1-2. 1 forsure. yeah i know xc you prob ride hard. if i see rough trails with big mougals, i think im in snowcross. i like taking care of my sled, but its to tough i just beat it. and occassional jumping is involved also.

so with that info. i think i'll take the 405's out of the question, now the 375's or 359's? how rough will it be? cant be that bad where its not fun to ride.

also, do the 405's feel like the snowcross sleds you sit on, that wont sag at all when you get on it? dont want that stiff.

what is your weight? If you are under 200 it won't budge with 405's

the .405 in my xc would top out with no weight on the sled and it might settle about 1.5" with me on it.... 235lbs no gear , so thats 245 dressed ! JB I think is correct under 200 solo it may not compress with just you on it! .359" is the stock spring at 77* , I am not sure that the .375 will be enough riding 2 up.... So I think knowing that the .405 will be to much solo the best guess it to try.375 set on high two up ......

I think most xc come stock with .375" , maybe see if anyone has a set for cheap money! There is a ton of sleds getting parted out in the parts section , I would think 30~35 dollars would get a set used shipped to you!

yeah im over 200. so the .359 is the stock springs in out sleds? i'm prob 230 dressed with gear on. right now i ride solo with the stock rear springs on high and thats fine with me. 2 up i think the track rubs a little bit on the big bumps so i want to get rid of that. so the .405 riding alone for you was too much?

Hello Prox700man.
Personally, if you are over 200 in your birthday suit I would go with the 405's. You can always run them in the low position when you are solo and crank em up when the g/f rides along.

I am about the same wieght as you and run the 375 in my pro on low and work good. With this new info get the 405. when solo move the rrss blocks all the way back and run springs on low clickers 0 and hopefully your fillings will stay in.

alright. if i got the shock revalved a tad stiffer would this help too? or should i leave the shocks alone. i rebuild them every year, and could change the valving if i wanted. I appreciate the info

if the sled is sitting in to far the shock vavling will just make for a harsh ride. You could use those over load cam blocks with the 375 springs but remember that the springs sack out faster with the over load blocks.

alright. so i should just get the .405 springs and leave the shock valving alone and run the clicker on 0 for the rear shock?

ive played with the clicker a bit and i really cant tell a difference between 0 and 5 and 9. all seems the same to me.

what speed does the clicker adjust. i cant tell a difference between settings. i'll get the .405 springs, but should i get the shocks valved a little stiffer while they are getting rebuilt or leave them?

I could be wrong but I think the ryde clickers are compression stroke only. The shim stack has both comperssion and rebound. JB am I correct in saying this about the track shocks ?

the clicker adjust compression only. If you are playing with the clicker in the garage you won't notice anything as you are not moving the oil fast enough.

maybe i'm a puss... with the 136 extensions I'm running the stockers and revalving this year, with the stock springs I have only bottomed out a couple times and I go about 210lbs... the problem is that with the stock springs/valving the little 6-12" washboard rattles your fillings out... now, I'm not johnny snowcross riding at 10/10th all the time, but i don't exactly ride like a 65yr asthmatic w/ a cardiac condition either... personally, during off trail excursions (more and more frequent these days) I find that a softer spring is better anyway... imho, the stock spring is FINE, revalve your shocks to fit your riding style and call it good...

well bonz, even i who weighs 180, maybe 195 with gear, need stiffer springs in the rear, the stock springs sag out quite a bit, i have opted for stiffer springs and put my rear rsss in the rear hole, that way i can opt for stiffer when 2up or have heavy load on, the stock springs are good when new and no wheigt transfer is needed, funny post thou, try a set of stiffer springs , opt for more weight transfer and wheelie over the moguls :div20:

i figured cuz i got my shocks redone if its not good enough il just buy the springs and put them on, still gota set up the seld right clutching and gearing.

I liked the shocks on my Pro-X as a 121". If I was to do anything I'd make it a hair stiffer. But now I'm going to a 144" and I'm hoping it won't feel alot softer now with the longer track. If it does I'm going to have to change some stuff next year.
