Thunder Products helix for the moutain sleds

[NOS-PRO]

Thunder Products is selling reverse angle 33/35 degree helix's that not only are clearanced out for the secondary coil bind, but will make the sled rev quicker, improves 60 foot times and would be a great helix for off-trail, mountain riding or very quick corner to corner trail riding.

Just completed testing on this helix with really good results!

Just got this helix , should spring be set at 3/1 as the service manual lists for US mtx or 3/3 ? Was surprised to see 3/1 in manuel .

3/3 or 6/1

Thanks, anyone know why stock setup is 3/1 , seems odd for a mtn sled.
