Had mine done by them this year. They take a cut off inside of s=heave on both faces and cut spring pocket deeper on helix so secondary spring doesnt coil bind.
In crappy conditions didnt see a lot of changes but on hard packed rd seen 196 km/hr. Never seen a speed like that since Ive owned sled. Never got a chance to put marker on sheave and see if belt is shifting out.
$100 well spent for me.
