I hate to say it, but they’re not worthy. But then again it depends on how aggressive a rider you are. i’m sure you’re going to hear from many other people.

 

Depends on my mood but yes I can get pretty aggressive, hit corners pretty hard

 

Throw them in the pile of parts you'll never throw away but will never use either. I'm a fan of Woody's mavericks, similar to Shapers but better quality imo.

 

Put the stock 4” to the outside of the ski and run 6” Woodys Mavericks. That’s my go to setup with Navigators.

 

Replying for future reference 🍻😁

I have the same sled but a 137. Riding solo I don't have much to complain about with the stockers.

But when I switch to the 2-up seat and the Missus comes along, I found that off camber corners it tended to push, especially when things were a little loose.

Full disclosure, I'm not a super aggressive rider looking to corner fast. So what is generally satisfactory for me might not be for someone else. But I do like FordFan's suggestion above.

 

I bought a 2025 137” MXZ 850 in the middle of last season. I normally do all kinds of mods including skis and carbides. Well, all I did this time was literally go from the dealer right to the trail. Made literally no changes and was honestly 100% happy with it the entire rest of the season. Complete surprise to me..

So maybe just ride the darn thing first before making any changes.

 

I always change the stock carbides as soon as I get a sled. They go back on when I sell. Always looks good selling a sled with brand new carbides on it.

 

They are made of a very good grade of butter. If you ride in whipped cream, they will be fine. Anything else replace them. Ski bottoms cost a lot more.

 

Scrap them.
There are new type of carbides called “cobra”. Is what this dealer calls them. Totally different sled with those on. More controllable in any conditions and last longer but I generally don’t run on roads, gravel or pavement.

 

Qualipieces (formerly Cobra) are basically a regular wear bar with the Navigator all in one piece. They're nice but expensive. Made in Canada I think.

 

On my '24 850 Blizzard 129" I moved the stock 4" carbides to the outside of the ski and put 6" Shapers on the center. The difference in handling, cornering ability, and tracking, was night and day. This is the way BRP should have sold the sled.

 

I did what a couple others said. I put them on the outside and put a better carbide in the middle. The stock carbide is very wimpy. I used them for awhile on my last sled and when I took them off, they were all bent up.

 

Definitely put the Qualipieces Cobras on it. They call them Adventures now. Move the stock to the outside for edge protection.

I ran Shaper bars for years. The Cobras stopped the darting and were way easier to steer. 6.9s and RasX skis

 

I'm going with Woody's Trailblazer IV 6" with the Woody's Navigators on the front. Put the stock 4" carbide to the outside edge.

 

A buddy has a '21 MXZ 600R 129" and ran the stock carbides with no outer carbide, and his skis got tore up in a few seasons. He later added Bergstrom tripples to the center and moved the stock to the outside. I just bought a '25 MXZ 600R 137" and did the same thing.

 

I'd run the stockers in the center, and toss an old beat up pair on the outside to protect the ski (if the 25 blizzard still has the pilot x with the outer carbide provision). Early season conditions will likely beat them up anyways, so may as well use em and then move them to the outside when conditions improve and put your choice up the center.
