I used current b4 diff bearings on the rear, and old school smaller flanged on the front.

Nice - thanks!

That's the way to do it... Thanks for the info.

Where did u get the tyres from?, brand etc, also are they a soft M3 compound?

They are losi step pin tires. fronts seem a little hard to find, I have been looking for some for a while. Rears are silver, so not that soft.

Traxxas makes a front tire almost identical to that one, in fact, I thought it was.

Somebody on ebay now selling those Losi step pins, I just bought a pair.

Yep, that is them.

These are the traxxas but not the same that RC10Sprinter has.

Will the Associated "Yokomo" packaged (HOT LAPS) Tires fit? They look like they are 2.2 TR36S as an example... I have 3 sets, NIP and have been trying to find them a home.

Can someone post the size of the bearings for the front (the older flanged) and the rear (the b4 style). I want to place an order.

Thanks!!

I am pretty sure they are the same size, just flanged and unflanged. 5/32 X 5/16. You could actually use unflanged on the front, but might need to use more spacers. As well, you could actually use the flanged on the rear. This is the size I used, it is a inside b4 diff bearing. The bearing has about 1mm play inside the inner rim. And fits snug on the rear axle. Hope this helps

original rc10 front wheel bearings are 3/16" x 5/16" flanged. rear hubs for b2/b3 are 3/16"x 3/8" unflanged(with 3/16" axles). B4 can have either the same as b2/b3, or a larger outer bearing.

I'm quoting myself cause I still want to know. The front wheels need some sort of spacer on the back, are you guys stacking up washers? or putting an extra bearing back there.

The inner diff bearings are 5/32x5/16 on the B-4.
