Interesting Skid Shock Spring info

Yes you went off on a trail based rant and as you do not list a sled I have to guess, and not sure by your pic we are talking SR Viper. .

Yes my "rant" was trail based on the 141" skid as I posted. As far as "But as you have already changed shocks, springs info on stock should be of little interest", I thought my post might be of interest to any new or potential XTX owners since I have plenty of time on the skid in stock shock form and also with aftermarket shocks and a triple rate front skid shock spring. This is a the stock skid and not a longer skid I cobbled together out in the garage. The talk of using a stiffer spring with less preload over a weaker spring with more preload is a no brainer, but in my experience and setup, I never ran into, nor did my friends with this skid have "too much weight on the front" to the point that we had to use more than close to minimum preload on the stock front spring or with aftermarket shocks/spring. I've used some quick limiter strap adjustments for trail vs off trail and all works well. Last season 95% of my riding was swapping back and forth daily between the 141" and the 137" coupled skid. I find that the LTX skid has more weight on the ski's than the XTX 141's. Not too much weight on the ski's that it's a problem but just more so it does surprise me to see XTX owners complaints of it.

I posted this in the first place only due to you saying that it was a "A must do for XTX in my mind." I don't think it's necessarily the case, but if some have weight issues on the front and the spring works for you, Great! By all means do it. Whatever works for you. I just don't see it as a must or a common problem and like I said, new XTX owners might want to hear that instead of thinking it's a must do.

Excuse any sarcasm or poor tone. I figured Stingray might understand it better when spoken to the same way as he usually speaks to others that have a different experience. :rolleyes: :rofl: :sled1:

If you enjoy a heavy feeling front that's good. But the XTX is not supposed to be heavy on the skis like a Nytro, at least not in my opinion and it's very easy to fix. If you like the Nytro heavy steering by all means run what you like, but my opinion is still the same that evening out the skid helps overall handling. Please do try the mod mentioned and let us know if your opinion is the same.
 
For my experience of riding friends L-TX, they are unbelievably light on the steering compared to my X-TX. They were way more easier to ride than my X-TX, at the point I wanted to get tid of the X-TX at first. Funny to hear some sled are the opposite.
 
Got my new center track shock spring from Zbroz Racing. Its a 145# rating, standard on alot of their setups. I think its safe to say our MTX's are undersprung.

Stock spring on the left, Zbroz on the right. The 145# spring is also 1/4" longer and .015" thicker wire coils. I will see how it rides tomorrow.

Stingray, I don't know if your an awesome mechanic or what, but my spring change was a PITA just rolling the shock back to get the spring off. CAT tightened the lock collar so tight I couldn't break it free with the spanner wrenches in the tool kit. I had to use a hammer and a screwdriver to break it free!

Also, with the lock ring at the bottom of the shock, I measured roughly 2-7/8" thread length. I set my spring collar to 1-3/4" or roughly little more than half the way up. Where is everyone setting theirs?

Mine set at 1/3 of the way up with the 135 pound spring, I recommend starting low and increasing spring until you get the front light enough for your liking.
 
i think all the suspension talk of viper xtx shouldnt be consider as trail sled and kept in mountain section
 
Sorry, but for me the XTX Is a 75% trail 25% off trail sled, or maybe there's not lot of snow on your off trail. My RMK Assault Is 25% trail 75% off trail. I know every people have different opinions about what is off trail for them.
Seriously, the XTX is an hybrid more axed for trail than off trail, as the Polaris Assault Switchback is an hybrid more axed on the off trail.
The Viper weight, skis stance, seat width and height, handle bar height, stiff Fox shocks and the fact this sled is so comfortable on the trails make it really more trail oriented.

Nope. I do not have a heavy steering front end. Wouldn't like it and never had it. I don't doubt that spring works well on those with a setup that has a lot of weight on the skis.

Depends on setup I suppose. Limiter strap settings, shock settings, etc, it doesn't take much to make them handle differently. I did run aftermarket front ski shocks and ski's on both of our sleds from day 1. The XTX skid has been in this Cat chassis since 2012 and heavy steering has not been a common complaint. Even moving up one spot up on the limiters makes a huge difference on my 141" as far as transfer and handling.

I don't know about that. There are a lot of guys that ride them on the trail. The setup that works well off trail is not a good setup for any hard riding on the trail. It's a machine of compromise. It doesn't do any one thing excellent compared to the other more specific trail vs off trail models, but it does a lot of things good.
 
xtx has same suspension as mountain so the skid set up for trail is pointless thats why hygear added linkage system and zbroz added transfer control kit too

XTX = 141 track with 1.6 lug
MTX = 153 or 162 with 2.6 lug

Follow NOS-PRO or shagman one time if you think an XTX won't rail a trail. Those guys were doing over 90mph on a 15mph forest service road and left me in the dust.

But lets not derail the thread we are talking about the XTX spring fix.

Heavens to Murgatroyd Stingray! No decent TY4 Strokers would ever do such a thing, and to suggest :nos-Pro & the Shagster...... hush yo mouth. LOL

Ordered a bunch of parts this morning including this spring. Can't wait to give You a feedback on this.
 
Ride report:
The heavier spring (145#) definitely helped. I think I need to go more pre-load though. I set it at 1/4" pre-load or 1.750" from the bottom. I'm going to turn it up another 1/4" for a total of 2" from the bottom. That will still leave another 7/8" of thread left for additional tuning.

Just a heads up, my spring is 1/4" longer than the stock spring, so my #'s my not directly cross over to stock!
