How straightforward is fitting the B9-503GPA set?

Fitting is generally simple for anyone familiar with differential service: remove the old gears, fit the new molded gears and secure the cross pins, then set mesh and test.

Should I change oils or greases when replacing these gears?

It is good practice to clean bearings and use fresh light grease or differential oil suited to your setup to ensure optimal gear life and smooth running.

Are these gears suitable for competitive use?

The molded gears are intended as OEM-compatible replacements; they restore expected performance but check your class rules and preferences for upgrades if you need higher-spec components.
