Rear fox air shock.

[snowhite]

okay I would truly like to know of the riders out there that hate that airshock on the rear skid? I have a'15 stxdx and that suspension is terrible... I have noticed that almost all the other models use the torsion springs and block system. Wonder why Yama-cat decided to install this shitty system in a crossover sled that needs the most suspension. Reason I'm asking is that with the seat being very firm, and no comfortable pressure setting on that shock it's the shits to ride this sled without getting sore!

Hated it in the xtx until I changed to the dual chamber hygear can linkage.

Okay but what's a dual chamber can linkage? Never seen that on their site plus what did it do for the sled? Ride,travel, bottoming, etc.?

Im lookin at that kit myself haven't found any bad reviews, appears to smooth out the studder bumps and help bottoming on the big ones, looks like a win win for the 141 track length. Never even heard of this kit til I met Ross at the Hygear booth at the snow show in Milwaukee last weekend.

this is the gygear kit, linkage and dual chamber for rear suspension .

The Hygear linkage kit only works with 141" skids, so I don't think that it will be any help to you. What Hygear does have is the "dual pressure" system for about $180 that you can add on to Float air shock, and it should make a big difference in the ride of your sled. I have an XTX with a 141" skid, and I ditched my Float 3 in the rear, and replaced it with QS3 adjustable coil-over shocks. I also added the dual pressure kit to my front Float 3's, and now my XTX rides and handles like a dream. There are ways to make that STX DX ride great, it just depends upon how much money you want to spend. With the price of the Vipers, it really is too bad that Yamaha didn't spend a few extra dollars up front and give the sleds the ride they are capable of with proper shocks.

The center shock also has a weak 110# spring requiring you to run too much air in the rear shock to achieve proper ride height. Last season I really cranked up the center spring to lighten the weight on the skis and found that I could lower the air pressure from 130 to 115psi at the same time and that almost eliminated all the bucking. With the 160# spring in the center at 2 turns from loose I now have proper set-in with only 110psi in the rear which should even help more. Added a Fettbros canister on the fitting to to soften the last 1” or so of travel too on my Float 2, really helped.

Adding a Hygear dual chamber or EVOL canister will allow the shock to be more linear and allow for more flexibility with air pressure settings. At the same time I would have the shock re-valved for your weight and riding style.
Most sleds come with a "one size fits all" shock valving. However we all ride differently and have different expectations of how the sled should ride/handle, which is why I have had the shocks re-valved on the last four sleds I have owned!
By adding the extra chamber and re-valving the shock(s) for your specific needs, you should be able to get the ride your looking for.
