3" track rubbing in deep whoops.

CUSO · Jan 13, 2021

I have a 2019 Summit, I switched out the 154 with a 165 track and rails.
I noticed on my last ride that the track seems to bee rubbing on the tunnel in 2 foot plus whoops while rolling over them.

I checked my track tension, and it seems fine, Just wondering if this is the nature of the beast, or should I be addressing something?

Spring tension, Limiter strap? go even tighter?

Anyone else have this issue? It seems smooth in all other conditions.

Is it possible its ice build up? Or is it there all the time.
I noticed alot more track rubbing noise with the shorter tunnel in these low snow conditions, over my 19.

Hmm I have a 2.8” track and I haven’t had any problems with rubbing. I have my limiter strap on the third last. It’s been running good going through some really hard whoops. I also have a air shock in the back instead of the torsion springs

I noticed the same issue on my 3” 165 alpha coming out of Renshaw after 400 sleds rode that day. It only rubs when the moguls are deep

You need to turn up the spring pressure or add some air to rear spring in skid if floats or turn springs up...fat boy springs if your a big boy....

Yeah, I have the rear springs maxed, but I am a bigger guy. Thanks for the tips!

Is it catching on the end of the tunnel or did you trim that all up?

Fatdaddy · Jan 15, 2021

My alpha track was leaving marks outside of the rail on the bottom of foot rail. I did tighten track after I noticed this. But will also tighten up back skid shock also as suggested.

hmm.. Good question. I never considered that. I will have to look.

Update, I undid the rear springs andcompressed the rear skid. No way it would be close to rubbing. I am thinking it was rubbing on the linq removable snowfall part. It was in pretty bad shape at the end of the weekend and spot where it mounted was a bit bent.
I have gotten a brake shape made up and am going too extend the linq bracket a couple of inches and make it more horizontal. I made a mock up and it all clears by about an inch and a half.

Pics to follow.

I only have the 2.8 and the stock rear brace and when I had my back shock out it never got close to rubbing. Mines only a 162 tho so maybe if you had a extra 3” it might

I have seen people are even having trouble with the 165x3 expert where the track catches on the factory short/mini flap.
Just watched a YouTube with a guy having to trim up the flap.
