Will this pulley kit work with my SX Eagle derailleur?

Yes — this kit is explicitly compatible with both NX Eagle and SX Eagle 12-speed rear derailleurs.

What is the correct tooth count for NX Eagle pulleys?

12 teeth on the upper (guide) pulley and 14 teeth on the lower (tension) pulley. These specific counts are required for correct chain engagement on the Eagle 12-speed wide-range cassette system.

How do I know if my pulleys need replacing?

Key signs: shifting becomes imprecise or slow; you can see visible tooth wear or rounding; pulleys wobble side-to-side; bearing feels rough or gritty when spun by hand. Clean and inspect after long muddy rides.
