SO last year, I found a decent SX to build up.

I did a complete top end already, added some C&A Razors, and installed a 1.75" BACK COUNTRY track, while utilizing drop brackets and 7 tooth drivers to allow this insane track to fit.

Heres the problem......

Due to the drop brackets and dropping down to 7 tooth drivers, there is WAY WAY WAY too much pressure on the curved part of the hyfax. This also causes a droop near the rear 1/3 of the track, and the idlers are fully tightened.

So, heres what Im going to try.

First off, I hate that the coolers are under the seat, versus on the footwell. I know some guys swear by having the coolers under the seat for protection, but these coolers are causing the "space" issues for me.

I am going to remove the under seat coolers, and either relocate the to the foot-well area, or Ill buy used SRX ones (bigger capacity i think??) and use those.

By doing this, I think it should allow me to go to 8 tooth drivers, and reduce some of the extreme twist on the track. This also means I can use smaller drop brackets, or NONE all together, and still have this crazy track.

Has anyone ever relocated stock under-seat coolers to the side rails? Anyone successfully stuffed an 1.75" track in an SX without rubbing?
 

i did this a few years back, relied very heavily on the front cooler to do its job. i didnt have any problems but that sled was ridden in deep snow, no hardpack. didnt see where you were from, but i wouldnt reccommend for a trail sled. did a newer proaction sled a couple years later, removed the under the footboard coolers and utilized polaris style edge coolant lines with a crossover tube at the rear. this worked well but when the kids cruised, the temp light would flash. i added a rear exchanger and incorporated it into the running board coolers and the issue went away. another thing i always wanted to try was eliminating the under the seat exchangers, hard-piping from the front cooler to the rear cooler using aluminum tubing mounted inside the tunnel at the bends at the top. picks up alot of room and they are away and to the side of the track and suspension motions.
 
the sx has front and rear coolers which ill be keeping for sure, but I also want to run the side coolers for when I am on hard-pack

I went to 7 tooth to clear ther coolers. So I hope I can run 8's once they are gone, and lessen that severe wear on the hyfax... Sam goes for the drop brackets. Although it does give more height, agin changed the gliding angle that the hyfax itself runs at

Im curious to see how it all works in the end
 
you need to re-think the mounting points for your suspension geometry. if you can find a 96 vmax mtn max for measurements, this theory will alleviate the suspension stress issues. i ran 1.5 tracks on both a 94 shorty and a 96 mm 136 and dont recall any rub issues. basically same chassis/tunnel combo as the exiter sx, thats where the 94 600 came from and was based on, and used 8t drivers. wouldnt think that extra 1/4" on the track would make a bunch of difference. if you dropped the rear without changing the front arm and upper center cross shaft mounting locations, i can see where the issues would be. its all incremental and proportionate movements to the amount of drop.
