That part number is for .375/47 springs. Those are made for a RMK skid and will give a much better ride...even for us big boys! The .405's are for two-up touring sled's. You can "make" them fit, but why?


7042079-067 Spring, Torsion, LH, STD [.375/47 °]
7042080-067 Spring, Torsion, RH, STD [.375/47 °]

Agreed. I have the .375/47 springs. Haven't tried them yet but im told it's the way to go. I'm maybe 190 geared up, but they say works great for big guys as well.

I had the 405 on my 07 and loved them, great for dropping cliffs too! why are the 375 better?

Mountainhorse can probably explain this better, but it is due to the 47 degree preload. They give you a more progressive rate during its travel, and not just a heavier spring. If I also remember right, others who have installed the .405 springs said that they do not fit correctly...I think they hit the rail at one point of travel or did not ride in the factory cams right.
