1.45 woodys up the center, 1.325 on the outside. That combo works for fast trail.
Stud boy 1.5 on ice or more drag set up.
4 per bar is nessacery.
Mixed doubles and singles for me, tons of scratch lines. Avoid the center 1" or so, front protector location.

Meat Head I am in same school of thought on lengths with 4 per bar and have done similar in past with slightly shorter studs on outside with what I thought was good results. Do you have pick of your track layout?

 

As meat head said 4 per row is the ticket! But I prefer doubles up the middle. My renegade xrs has 192 1.575 woodys mega bites in studboy prolite doubles. On hard pack it will easily lift the skis 3-4’ at 25mph.

 

Calcrn have you used the Prolite backers in past? If so how many miles and with good longevity? For every good report on them it seems like there is s negative report with there use. I had them on a 800 a while back and didn't have any issues.

 

That Track is designed to have a little side slip in the corners. Notice the large taper on the outside lugs. This helps the sled rotate in the corners (point and shoot). Studs on the outside will hurt the feature. I have the same track and backers with the same pattern. Works amazing!

 

So you are running (2) DBL Prolite backers per lug all in center?

I find the sled back-end will really "skate" without studs on outside belts when you are riding hard on hard/icy trail conditions which we see a lot of in northern WI plus .

 

Not 1.25 rip 2 .. but this is how I roll

 

I use that pattern as well....yes it works great ! Best drag setup I have used.

Yes,
I am running (2) DBL Prolite backers (the wider spaced backer, 1.20" spacing) per lug all in center. MXZ 850 1.25" Ripsaw 2, 1.50" Studs. I have low miles on this set up (only 500). I have not got into a skate situation so far?
Hope this helps you!

By the way, Stud Boy has a Heavy Duty Template made only for a RipSaw 2. It fits very tight and helps get the backers (Holes) square every time. It still takes time and attention to detail. The Backers are tricky untill you get good feel for them . Warm soapy water soaking the backers. I used Dawn Dish Soap as lube at install, with it on the stud and q-tip soap into the backer holes. You have to sneak up on the final torque. I used a long 1/4 drive rachet and slow an deliberate motion to finish. The backers will strip out in not carefull!
Good Luck!

 

Think about this on the backer subject, in the last 75000 miles or so I have not broken a aluminum backer, bent yes broke no... think about that before you temp fate... just my take on it.

 

I agree I have bent a lot of aluminum but never broken any. But I also go over my sled after every ride and I wasn’t missing any studs or having them very loose. Just some backers cracked. I personally think it was due to the soft lugs of the storm 150 track folding right over and the backers catching hard on the ground early season before we had a good base.

definitely looks like it caught something with the stud and backer on this side.

I haven’t broken any in my 2020 and that sled has been ran way harder in marginal conditions than my 21. Have you ever tried them Meat Head?

Thanks for input everyone.

Meat Head who's template for your layout?

View attachment 1980391

 

It's a ripsaw 2 1" but thats the pattern I use on all 129" tracks. I run the 1.25" a couple yrs.
This 1" I used 1.175 woodys up the center and 1.080 stud boys on the outside.

 

Thinking of installing standard alum backers, had the Stu Bot Pro Lite plastic backers on a 2015 800 X-RS with good results, they really hooked up in hard pack and don't recall breaking any but going to KISS (Keep It Simple Stupid) it this time.

Going to start with 90 (2/lug) 1.450" up center belt and 15 (1 every 3rd lug for 30 total) on each outside track belt . This will give me 120 total. Had similar setup with 90 in center and 22 on each outside belt (all 1.325") on a 2018 X-RS and felt outside belts had a little too much bite when things get tight/twisty northern WI groomed trails.

So are you 2 ply guys running the smaller 2 ply studs and backers? I talked to 2 different stud manufactures tech support guys, and got 2 different responses. 1 tech said he see's lots of guys running the larger 1 ply stud/backers on 2 ply tracks when studding lighter for added support. Other more conservative tech support said not to doo this as the single and double ply studs have different shoulder heights where the stud backer seats.

 

Second guy is more accurate. Use the smaller ones for the 2 ply.

 

so I see preformed buttons on the track ? 137 renegade 1.25 ripsaw ... do I use those ??

 

Yes, make sure you know what ply track your studding as well.
