Has anyone tried bergstroms ski rubbers? Not their shims but the actual rubbers that they built the angle into. I bought them at a sled show a couple seasons back for 30 bucks just to try out. I’m going into my third season with them and have been quite happy with them.

How many miles are currently on the sled and how old is the belt? You could need a new belt and clutching refresh depending on miles. Springs wear out. This sled can really wake up with just a few small changes.

Check your throttle cable and have you swapped out the relays for the better ones? Also could be TPS out of adjustment.

Thanks for the recommendations I’ll make these changes in the off season. I just added dalton adjustable weights as well before I put the sleds away for the summer. Set them at 69.2g and will adjust from there after seeing how rpms are For the slick washers I’m assuming you just use the 2...

2017 pro-s switchback 800, with ice attack XT track. I’m currently geared 1.74, running 120/310 white venom primary spring, 10-68 weights, 140/220 secondary spring, 48/44 helix with one Delrin under the cup and gates belt. Sled pulls hard up to around 95mph then slowly creeps up from there...

I just got back from a 2 day ride where the trail conditions were pretty bumpy. Lots of railway beds etc. My sled is new to me 2017 pro s le 800 with ice attAk xt track and hi/lo we shocks. I set all shocks to factory preloads and clicks prior to leaving for the trip. My skis have shaper bars...

Curious How did you find the setup prior to modding?

XCR solid bogie wheel kit (4) is part# 2881955 XCR rear axle wheel kit (4) is part# 2881954

I noticed the NSP kit is an extruded plastic bushing kit. I’m curious in which would be more durable

Thanks guys

I know this is an older post, but thought it would be better to reply here vs. start a new one. When you order these how many kits are you ordering? Do you need to order 1 kit per side or does 1 kit cover both a-arms? Might be a dumb question, but wanted to confirm before i went ahead and ordered.

I suspect you'd get a bit smoother ride going to the 137" Pro S setup. That's just based on what i've heard guys tell me though comparing the two.

I’m sold! Gonna buy an orange one for mine

I really like it. It looks sweet I may have to get one in orange. :) The only thing I’m curious on is how water/snow will drain out of that v grooved area. In the pic it looks like it will collect there?? Maybe through the hole where the rivet goes through? I always wipe my sled down...

Thanks for the additional feedback. I’m currently gathering parts to do this change I’ve got my 120/310 and my 140/220 springs along with 3 Delrin washers now and the 48/44 helix was ordered last week along with a new gates belt. Ordering my 40t gear and 70p chain tomorrow. Looking forward to...

I like that too. Thanks for posting Do you have any other pics from either the side or looking straight on from the back. I’m trying to visualize how high it does actually stick up.

Hey Racerdave A follow up question. I now have my new sled and the track that’s on it is the ice Attak XT with 1.22” lug Based on this I just wanted to confirm that you’d still recommend the 48-44 helix. One of the guys I ride with has offered to sell me a northstar Rick custom cut helix but...

I’d like to know this as well
