Hi Everyone,

My season has ended and it's come time to sell my current sled that I've been riding for 4 years. The last 3 years I've been riding with a Kmod and Raptor shocks so I thought I'd make a review video on the suspension.

Before I get to the video, I'd like to talk about a few things that I don't mention in the video.

Shocks:

Most of you guys are aware that the Raptors are great shocks. I can attest to that. Dropping that coin initially was a tough pill to swallow but after decimating the stock shocks in one year, I knew they would pay off in the long run. And they have. They are sooooo much nicer. Both off trail and on trail. When it's super deep, yeah nice shocks don't do much for you, but lets face it, we ride crappy trails and mediocre snow most of the year. I was able to tour Raptors shop and meet Jake when I interned at Polaris in 2012. Jake is super passionate about suspension and regarded as an expert among his peers. His shock technology is top notch and he really cares that people are getting the most bang for the buck. My first set of springs were chipping and I called Jake to let him know. He sent me a new set right away no questions asked whatsoever. Thats customer service! I gave my chipping ones to my buddy for free. He powder coated them and ran them on his walkers.

The valving is basically perfect as far as I can tell for the beginner to advanced mountain rider for both off trail and on trail. The clicker adjustment makes a huge difference. So much so that fully maxed out it is a miserably rough ride. But if you're going to huck some seriously big jumps, this is a great feature. Small changes make a noticeable difference so it's rather easy to dial these shocks into your own personal sweet spot. I really couldn't be happier with my shocks and will be getting a new set with my new sled.

Kmod 37" A-arms:

Ive had a few different kinds on a-arms on my sled and these are by far the best. No spindle interference, tight delrin bushings, quality heim joints, and a perfect balance between tippiness and stability. It took me a while to get used to the 'quickness' or dare I say 'flickability' of these a arms in conjunction with the Kmotion, but once I did, I really liked it. I run my skis in the middle position and that also helps with the ski bonering problems and keeps the rubbers alive longer. I would compare the 'quickness' of my Pro with 37" arms and a Kmotion to the stock 'quickness' of an Axys. I've ridden a handful Axys sleds this year and had zero issues with how quickly it reacts to rider input. My Pro with 37" and Kmotion is just that much easier to ride that it's on par with the new chassis. I can't wait to see what the Axys will be like with the same suspension I had on my Pro!

Geometry:

I ran my limiters all the way out on my Kmod. You can really see the difference in what that means when the suspension is fully dropped out in the following pictures. With the stock skid, with the track just barely touching the ground, there is about 1" gap between the track and ground in the front. With the limiters all the way out on the Kmod, the front of my track is touching and the rear is about 2" above the ground. This makes the Kmod super playful and I love it for that. And since it's a coupling skid, once the skis are in the air, it dynamically starts to pull the front of the skid out of the snow to better keep you on plane. Longer limiters plus coupling equates to about the same flotation as a stock skid. If I wanted all out flotation and hill climbing ability I could pull those limiters up into where the stock suspension is AND have coupling and it would flat out launch onto the snow and provide the best flotation and hill climbing ability possible. I like to wheelie. I like to do hop overs, turnouts, no ski sidehilling, etc. Its super fun and I love to be able to do that yet have good flotation when I need it.

Here are some more pictures of the wear and tear on the skid in 3000 miles. No issues whatsoever. In one year on my stock skid I bent the rails, snapped multiple bolts, broke the front torque arm, and all my pivots were so sloppy the first 2" of travel were just pivot slop being taken up. 3000 miles on the Kmod and zero issues.

Nice review Tory, makes me want to spend my tax return on mods instead of the house :face-icon-small-coo

When you upgraded to the kmod skid, did you end up reinforcing your tunnel too? Or didn't you see a need for it?

I tried it without braces and started to buckle the tunnel in front of the stock braces. Then added the Kmod braces and it's been fine for 2500 miles.

Great review! Have enjoyed mine this far( 700) miles and it's so great to know you put 3000. Got lots of life left then! K mod is great stuff and good customer service. It flat out works !

Definitely! There literally isn't a thing wrong or loose with mine. It will outlast the life of the sled quite easily.

You said you like the k-motion setup but is it worth the $400 you paid to upgrade? Just curious.

Depends on the individual. If you're young, strong, and aggressive I don't think it's worth it. I herniated a disc a little over a year ago so ease of riding is a top priority to me and this fits the ticket. If you're getting a brand new skid it's only $200 extra so at that point you might as well get it because it has a lockout so you can run it rigid or flexy. Theres more added tippiness with the 37" a arms than there is with the Kmotion. FWIW

I've mentioned this before in another thread, but in addition to the superior ride you get with the Kmod skid, you can easily transfer it to another brand of sled with a few parts you can buy from Kevin at Kmod. This makes it more of an investment instead having to buy the whole kit again if you switch to another brand.

For instance, you buy the turn key skid for your Pro-RMK and then for what ever reason you buy a another brand, all it takes is either 2 upper cross shafts + some spacers or new rails depending on if you go with Ski-Doo or Cat.

Tory is spot on with the ability of this skid to handle the whooped out trails.

How long distanse from bottom on rails to upper from arm,12.5"would like to get mye kmod conversion kitet as playful as your turnkey skid. Think the kmod 37" arm is something to consider.

I have my limiters set up at 12.5"

Good write up, thanks.
One question, why have the drive nubs been hitting the front torque arm? The witness marks are all the way up the arm.

Tony, I think that's from the combination of running a 3" track too loose in the Pro tunnel. I'm not sure you would see those rubber marks with a track that fit better.
