Yes, when fitted correctly and paired with proper diff oil and setup, the plastic pulley performs well in club and regional competition as a reliable drivetrain component.

Any tips for installation?

Clean mating surfaces, inspect splines and teeth, and use the correct screws and threadlocker if recommended; assemble the diff on a clean workbench for best results.
