POLARIS VR1 BOOST REAR SUSPENSION VS STANDARD VR1 SUSPENSION. WHAT HAS CHANGED ANY WHY? 

Great video and explanation of how the coupled suspension works. Just having 100 thousands difference in the setting of the couple blocks creating the coupling effect and how Bruce explained it, was great. Keep it up guys and looking forward to more this season.

This video provides a lot of fantastic content that is really beneficial to the entire Polaris community. Thanks so much for making such a good video!

I'll admit that I enjoyed your videos from 2 years ago (from a viewing point), when you were just ordering parts and installing them on your new sled. However, from a learning point, you can't beat Bruce's vast knowledge of how snowmobiles work, and how to adjust them to do what you want. Keep up the good work!

Best suspension tutorial I have seen. Thank you Bruce and Jesse

Great vid and tech tip. I had a xc137 with xtra hd springs, used it for two up riding in Norway. Best trail sled ever as long as I remembered to change my spring settings, coupling blocks and shock settings.

The point of coupling as the gap closes is sooner.. when the skid is coupled, front and rear springs and shocks work together.. even with softer springs.. in other words.. you get a help with ride and maintain greater ski contact…you get more done with less…and compared to the longest delay in coupling and the rear kick or Buck, where the front reacts to the bump then the rear takes a greater hit from the rail angle increasing, no kick when coupling is fast or sooner (smaller gap)

Excellent explanation of transfer and geometry of both skids guys, loved the flat bar idea to simulate actual travel. Great work guys as usual. Thanks and kEep up the good work!🇨🇦

The most informative sled channel I’ve seen. Thanks

I’m learning a wealth of knowledge with these videos. I was in Southside last Saturday Bruce loaded your sled while I was talking to him. Do you guys have a video on how to pull the skid out of the sled.

This video was awesome I couldn't ask for a more awesome show of how the front and rear springs work together,I'm glad the set up I'm going with this year the 95/300 lb progressive spring from switch back xcr in the front with those 14 lb trap springs from the adventure X2 650👍👍

Great vid guys. I have two questions for the VR1……1. Are those scissor blocks supposed to rotate by hand like in the video? I can’t move mine by hand. I’m gonna have to loosen the Allen bolt. 2. Can the aluminum scissor block on the boost be put on a vr1 frame? You said skid is the same from the scissor blocks to the front. It looks like the boost has a much beefier skid in the rear (more metal supporting the frame)That would be sweet for more adjustability if possible.

Enjoy the technical videos. Can’t wait for mine to show up.

Another great video, good work guy's. I can set up my buddies boost for him now.

The best geometry videos ever👍👍

Great Video. I would really love to see a breakdown like this with an IGX assault skid!

Good stuff guys great content really helps understanding our sleds suspensions

Very cool! Would love to see something similar comparing the assault to the Indy.

Can't stop the questions How does Bruce set up front shock preload? Does he use factory recommendations? Because factory recommendations don't include where the limiter strap is,If you shorten or lengthen the limiter strap it changes your initial preload? If you could guys could comment on this I'm sure more guys have this question....👍👍

Fantastic work.thanks keep them coming.

Super info! Thanks. What benefit does the 4th rear idler wheel have? I see some have 3...some have 4.

If one were to remove the blocks all together, it'd be a wheelie machine for Miles I guess ...but ,would the rear arm hit the inner rear wheel ? I know it'll ride like sheit ,but may be fun to try it here and there on the lake.

Great video, thanks for sharing the knowledge and as someone who runs a business to be taking the time out of life to pass these tips along is much appreciated! So I have a 23 Boost VR1 137 that is on a truck to my dealer in Maine. After watching this I have spring questions. I consider myself an aggressive trail rider, love some bumps, 45, and about 240lbs (working on that) what do you suggest as far as spring and shock settings. My dealer is good but not sure they dive that deep into these factors in dealer prep. Thanks again for the great vids, keep em coming.

Great to see the rear skid in action! What grease do you use? Do you guys disassemble and lubricate?

My h/d trap springs finally shipped hrs ago👍👍I priced that coupling set up but it's almost 300$ for everything..

Can you do this exact video but with an assault skid. I think it’d be a great video because those sleds are so popular and people may not know how to set them up properly.

After watching this I'm excited for you to get your boost! Hurry up haha

My buttocks mentions that the Vr1 is not at the level of the R-Motion. The progressive damping of the front shock absorber is much less. The mounting point of the R-Motion shock absorber almost opposite the mounting holes on the chassis, which allows for a longer shock and its slightly flatter angle towards the front, and to have a heavier spring without being too stiff. Polaris is almost there.

EXCELLENT video! I have a '22 VR1 850, I believe my RRSS is set to medium, which is what it was when i bought it. I'm about 250#, I have the HD springs on mine. Mine likes to pull the skis under power at just about any speed, plus I have a hard time with ski lift when cornering and getting on the gas to accelerate again. It also will bottom out on square edged bumps or when you go up and over a nice roller hill where it feels like you are almost airborne, then you see the "hole" at the base of the hill that you have to quickly stand up to absorb, I always bottom out. Don't want to set my torsion spring TOO high or my ride height will be too high to recycle the snow onto the heat exchanger either. Would I accomplish a better ride experience by simply moving the blocks to the high? I mean is it as simple as a quarter turn "could" make it a different machine or am I dreaming?

I think the Pro CC has a G out bottoming problem because of that front coupling,I think it let's the whole suspension bottom out way to easily,and I also don't understand why you would have those upper idler arm wheels mounted to the rear torque arm? When you're hard on the throttle isn't it pushing down on that rear arm? As opposed to an IGX that has a shaft mounted upper idler wheel?Which in practice isn't affecting the suspension when hard on the Gas?? Could probably talk about this all day 😂😂😂 Sorry for all the comments....

Got a new 129 Boost coming. Sounds like for aggressive trial riding, putting the rear block on four might be to much. I may start with position 3 and play around. Do you think the stock torsion springs for 210 pound rider will be good, or what would you recommend? Thanks, and great work on the videos!

So do you think that since they felt the need to add 2 new block settings to keep the power under control that the uncoupled assaults are going to be wheelie monsters?

In video Bruce was saying if you don't have heavier springs the track will rub the top of the rear shock welli put in hd springs and the track is rubbing the shock could this be that the track isn't tight enough

So, can you replace the couple blocks in a VR1 with the boost VR1 blocks? Great video.

Thank you great video

Jesse, wondering where I get those 125 lb springs for the front suspension of my 22 XC850

Great information.

Very informative post

220 lb rider on a new VR1 Boost 137 - I probably need the HD springs?

Hey Jesse! I’m looking at playing with my coupling blocks on my 23 XCR…I can’t seem to turn them around. Am I stupid or what? What’s the trick?

Any chance you know what the center is on that custom limiter bar he made? I have the same skid I’m putting in a mod sled and would like to know. Love your videos. Thanks!

Wh are the differences between the 23 vr1 and a 21 assault 146 matryx?

Great video

HI Jesse did you ever adjust the blocks on your 2022 XCR anda ifso what settings did you use Christopher ottawacanada

Jesse What is the spring for the non VR1 boost, is it the same spring they used on the 2022 XCR?

Was wondering what gauntlets you used? I can't find them in the videos. Thanks

Aluminum transfer blocks….. now I know why they are $25,000……. I’ll take two!!!!

I love how this video is done today but yet people have sleds there that are not being finished. I get the video but snow is almost here and Bruce should be helping in the shop to get the sleds to customers!
