Default ski darting on my 2015 switchback

Hey guys,just looking for suggestions on how to eliminate darting on the front end of my 2015 switchback.This is my first twin cylinder(light front end)I've been riding nose heavy triples since 1989 so this experience is kinda new to me.We used to rectify this condition with easy steer or true steer plates.i hear twin 4" carbides work but I'm afraid i'll lose top speed.Wondering what you guys think?Thanks

Set it up for your weight, adjust the time, shim the skis and then see if you still have a problem

which switchback is it? Pro-S , Pro-X or 600 Switchback SP?

also check for correct toe out and for sloppy bushings in the a-arms. Shocks in need of a service will in my experience make the front end feel nervous too

I made my own ski shims out of a piece of Hy-Fax. There's posts on HCS about it. Made a big difference. Not very hard..

did the same and made a difference. Note that there is no cure for tracking into other peoples tracks that have dual carbides or those super trackers that dig a trench in the snow. It is what it is

I've got a 15 switchback adventure, Bergstrom triples, ski savers, and shims. Lighten up the front end and soften up the clickers, works for me and I'm over 250 lbs. Dual carbides work also but nothing is perfect and all have draw backs. Stay on the throttle lean back and have fun.

thanks guys for all the great ideas.I tried to take out the ski bolt but she won't budge.The bolt turns fine,hit the thread end with a punch and hammer but no go.Wondering if there is a notch in the bolt that is timed to only go through the ski one way?How thick of a shim should I put?It's a pro s btw.What would that thread of ski shimming be listed under?

If you do a search "Polaris ski shim" on YouTube there's several vids to give you some info.

I know a lot of people don't like them but I have been using Woody's Dually's for years and they work great! Have them on my ProS and had them on my old ProR. Sled tracks straight down the trail and corners just fine for me.
