Metal diff pulleys

Do metal diff pulleys make a big difference. i have a TA04 and i took apart one of the diffs today and it was striped. du think that i should replace it with a metal one or a plastice one?

plastic is better! less drag and helps motor to run at a better rate car should be quicker and have more punch and could give more run time ..... It's all about making the car run free with little or no drag.. have fun..

I have Tamiya alum. pulley on my 414 and they sure are heavy. I'm thinking about change it back to original black plastic pulley on front, but keep the alum. on rear.

sounds ok! alittle more weight in the rear will help with tracksion and front should spool up a little quicker making the front of the car pull harder,, good for those turns. and sweepers.. just drive it like you stole it...and have fun....

i replaced the plastic pulleys in my 414 with aluminum ones. the metal ones are indeed heavier but i run in a dusty & dirty track. the metal ones seem to hold up better than plastic and theyre easier to clean - the black bits of dirt are easily seen against the silver pulley

These also will not melt when your diff would happen to spin.

The metal pulleys have plastic inserts for the balls.....these will melt instead!!

That's why I keep the rear to prevent heat up. I think the insert will stay longer using alum. pulley like heat sink. Front don't have diff ball.

Dtm, you are wrong. The inserts are made of teflon and you can put them on your soldering iron without melting.

I had very good experience with the alu. ones at he rear as well.
They definitely do not melt but they ware-out.
Can actually someone tell me where can you buy only the teflon bushings?

Thanx

The bushings have a long order number, they are listed in a 414M manual.
