Ski Doo QRS Secondary Roller B&B Monster Tuffs

Before:

We can clean up your clutch halves in our Machine Shop!!!

​It simply tells the computer that the sled is running at 110 degree's. No more having to let your sled cool down before another pass!  It is a big pain to get the temperature sender out so we made it easy to install, just unplug the temp sensor from the harness, plug in the "Race Plug and Go" and your ready to race!!  We recommend that you install a aftermarket gauge so you can see what the true temp of the engine is...
Note:
**** YOUR WARNING LIGHT WILL NOT WORK WITH THIS INSTALLED****

​The "Plug N Go" just tells the computer that it is running 20 degrees cooler. The sleds that have the bar gauges run most of the time here on the flat lands at 135 degrees (4 bars). 104 degrees is 3 bars, 140 degrees is 5 bars. So you can see there are 31 degrees between 3 bars and 5 bars, with running temps at 135 degrees. It only leaves you with 4 degrees before timing retard. The "Plug N Go" is just to prolong the pain of the dreaded timing retard.

It is hands down the edge over the sled without it!!! Lake racing, trail riding, extra 2000 feet wide open, or an extra 1 or 2 passes.

This is nothing new at all, many race shops use them. It is just a big pain to get the temp sender out so we made it simple to install. We ran these on many sleds before we were ASKED to start selling them. We find that they are nice to use with a gauge so you can see what the true temp is... remembering that you are 1 bar warmer. And those who do not have gauges the light will come on with enough safety to warn you before engine damage occurs.​

DooDoctor's Floating QRS kit!  Is there a Difference???

The answer is simple.  Our kit is designed with floating in mind, along with direct fit!  Our shaft is considerably stronger with .090 larger O.D. along with stronger shaft material for longevity.  Wide heavier duty bearing for stability.  The carrier on the end of the shaft reduces wear and supports the outer end of the clutch.  This stops shaft chopping and holds alignment.  Stainless Steel Seal Race.
