Mine aren't GFB guys.

I've been told the early GFB ones were not lining the alt, p/s and crank correctly. but apparently you could tell because they would wail like a quiet gilmer belt system when reved hard.

Mine are quiet, no dust , belts fully seat in the grooves.

Most importantly the pulleys track better than the factory POS balancer.

Mine are 'Forged' branded T7 alloy pulleys.
