What am I missing here? According to the picture you posted it says 35/39, yet newtron has a picture of his cam that says 8KC70 which is the straight 37 according to the book.

In your first pic it shows that the ID mark for a straight 37 is 8KC70. In your fourth pic it says stock spec is 35/39.
Newtron's pic of his srx shows 8kc70.
I''m thinking there is a publication error in the fourth pic and standard spec is straight 37.
My 19 ltx also says 8kc70

Look at the note, says theres a ink stamp on the driven sheave. The 37 has been machined to a 35-39 from what it says. Looks like they lightened up the drive clutch weight rivets to compensate for lighter driven spring also.

Hi there I thought the 35/39 was the helix of choice with a tune or without?

Ah, thanks guys. Mine says 8ma00, but no x. I just took a look at it, and it is clearly machined. Of note, I have 7 miles on it, and all rollers are leaving equal markings on each ramp, so that is certainly good.

I thought this sled had special "low preload rear torsion springs to provide a lower ride height", the PN's for them are listed as the same as on previous models? Was looking forward to upgrading mine..
