does anyone know if the aftermarket aluminum diff cups for the front and rear differentials will work on the center differential. also are these diff cups even worth the money? will i have to rebuild them less frequently if i use aluminum ones?

i ask because i used a tekno rc conversion kit and have gone brushless with a mamba monster kit. the power is ridiculous and i dont want to grenade anything and want to beef up anything that is going to give me issues. what other areas should i build up in order to prevent catastrophic failure?
