How hard would it be to make my 129 Rtx Le uncoupled or throw a 141 uncoupled under the tunnel?
 

I have the blocks out. I been riding with some Polaris 144s this winter and man they are having a lot of fun pulling the skis up. I can get them up but not like they do. An uncoupled suspension would be a blast. Bet them Polaris riders would switch over if they rode one

You can pull the rod as long as you have the stock rear wheels.
 
Wouldn’t the metal bars hit the wheels or the axle shaft?
 
tighten the front skid shock and or lengthen front limit strap for more fun factor - uncoupled is the way.
 
What are the nuances between the skids in these sleds? My BTX is uncoupled does it also have the sliding front arm or is that only on coupled ones? What are the weak points by the different suspensions? I actually really like my uncoupled BTX with the float 3. I was expecting it to be horrible but man it really soaks up the junk well and no bottoming out yet.
 
another thing u could do is pull the square plastic blocks out of the tranfer thingee - itll weight transfer better but still is coupled -

Yes that would be nice to know. I would like to be able change out a skid component to make it a truly uncoupled suspension.
Is that possible ?

I have a hard time believing that by JUST removing the transfer rod and blocks, you now have a fully uncoupled suspension.

I had mine set up for max ski lift on my first season with my LTX-LE. Limiter straps on last hole, front suspension shock at a much stiffer setting, and transfer block and ROD removed.
It may have come out of the hole a bit better, but still did not lift the skis more then 3-4 inches, unless I was in a f00t or 2 of loose snow. Then it would dig and lift the skis quite a bit, but only because it was digging a trench ! It still did not want to lift skis over hills much more then stock. Then again, I was not studded.
I reverted back to almost stock settings for corner to corner handling when riding hard.

Would have to have the 2 suspension out and side by side to see the diff.
 
pulling the rod and blocks un-couples...if you arent lifting the skis enough then...its either the limiter strap and or rebound setting on the rear qrs3r

So you are saying that the transfer rod set up is the difference between my suspension and the BTX, XTX uncoupled suspension ? That is it? I mean besides the shock package that you chose, LE SE etc.
 
uncoupled suspensions do not have a transfer block setup ....removing essentially accomplishes the same thing...however...the rebound the qs3r and the stiff torsion spring are factors here as well...and the weight of the rider vs opposing forces...
 
These torsion n springs are heavy, I'm 270 and it only squats 1 in on lowest setting. Does anybody know which one I can change to?

OK, Thanks for that bit of info. Did not realize that was the piece in the suspension that made it what is called Uncoupled. Huh, just by allowing that rear to drop that extra so many inches.
