501x Diff Balls

[MotoRev]

Hi,

Anyone know what size they are? Are they the 3mm by any chance? to fit the big pulley Worlds edition..

Thanks..

[steveproracing]

yes, they are 3mm on the big pulleys(and small pulleys)
oh and remember they use 12 balls in each pulley
and new packs tend to come in packs of 10.
hope this helps

Run 18 balls in the diffs. Use the spare holes. Less wear on the diff, and you can run it looser and still not slip!

Is that really worth doing? I am planning a DB01 diff rebuild soon with the 501x diff halves etc.

Definately worth doing in my opinion. Less maintenance, better performance.

I would recommend everybody to change the tamiya lightweight diff balls for ceramic!

I race indoor on polished floor and had to rebuild diffs after every meeting as they were very rough!

I upgraded the standard diff balls to ceramic and have raced 15 meetings without touching the diffs! Also change the m2 bolt and lock nut in the diffs, so once they are set they wont loosen!
