I like to give my testimony.
When I was testing the 1200T (300hp) these rollers were one of the first things I changed out on the clutches.
Had the clutch open to full shift overdrive in less than 1000 feet and hold there running at full shift for another 500 feet before 700 foot shutdown - basically blowing a belt every few runs. If a secondary clutch had feelings, I would not want to go through the agony from the torture we put that secondary through.
Did testing for a week with the QRS secondary on that sled ranging from 210 to over 300hp and I had that secondary apart more times than I care to remember.
Every single time I changed out the helix I would clean the dirt off the roller and inspect for crackings or anomaly and found nothing - what a stout little roller that held up to low helix angles and spring forces of over 280 lbs final force with pretension values of 28 lbs - i'll tell ya that for me to open the secondary clutch up was literally 2 hands on the opening tool. The guys would stand there in awe at how tight I had that secondary wound up.
Now pile in dalton brute levers with 26g flyweight in clicker 1 and the custom ground ramps I made - that secondary went through torture the secondary opening up to full shift locking the secondary open against the rollers trying to put a flat spot on them.....nope always come back round with no dents.
The rollers are still in that sled and run all last season with 220~230 hp and from what I know of still holding up well.
Bravo on job well done, my hats off to you on one strong little roller - i wish you made them for the 06~07 RER secondary. I will be ordering another set for my xp.

The picture below illustrates to what we were doing to the secondary clutch too.
