rear tunnel support on 12 sleds??

[tbeaton]

did they change anything about the rear tunnel support from the 11's to the 12's? obvioulsy it is a known weak spot on the tunnel for the 11's. trying to figure out if i need to buy some aftermarket support plates. what causes these tunnels to crack there?

I worked on a 2012, and it is identical to the 2011. The faille it is caused by some factors.

The thinness of tunel material
A bad design at this particular area.
A hardcore rider ( big jump, cat walk, etc,etc)
Too much weight on the back (ex, fuel)
And some driver tie a sled whit excess weight

The reinforcement plate is thicker with some additional rivets.

The reinforcement plate is thicker with some additional rivets.

so it has changed a bit?

To me they look the same.

i have a 2011 and a 2012 sitting side x side in the shop. the 2012 plate is thicker and has more rivets.

huummm!?? There, the oem 2011 and 2012 parts is identical.

The difference on the caliper is the coating on the 2012.

I hope it is a strong coating.

So the 2011 has more rivet holes

is the material the same from 2011 vs 2012? Wouldnt more rivets on the 2011 make the brace a stronger setup then less rivets?

Different material would be my only question. Easy check, grab a magnet.

Ha!ha! This 2011 parts come from a sled fixed by a crazy dealer that tried more rivet. Completely bad idea....

Note, the black arrow indicate the original holes.

 

[tbeaton]

so basically they did nothing to fix this known issue?

From what I have seen the only time it is an issue is when you have more weight on the tunnel then the 15 pds polaris reccomends..and you bottom the suspension...as long as you stay below 15 pds or dont bottom the suspension hard it is a non issue..I install custom side plates on my sleds because we pull loaded tow sleds to haul fuel and food to our cabin 50 miles from the road...we have done these on dragons, pro's, xp's and a few older cats...

Ak are you selling those? If so how much? Feel free to PM if you'd like.

 

[Effika]

And this kit can fix the problem.

sled

polaris told us the 2012s are fixed, all we did on our 2011 is added more rivets to them before they bent and they help up fine after that
