I have to rebuild my gear diff, I think it's worn out. There is quite some play when I hold the spur gear and one wheel. Also in corners I'm loosing traction and it takes too much time to build up speed again.
What are the right metal gears? These: 335030 and this would be the right metal diff pin: 335080?

So I've been out of rc for quite sometime and recently I have gotten my son into it. He is due for a new chassis and I've always been a fan of Xray quality over the other brands so I was considering picking him up a new XB2 but how is parts support for this vehicle? I have no problem stocking up on parts that aren't available at the tracks he races but it appears a lot of the basic items a guy would want as spares are out of stock even online.

Most everything I would recommend as a spare for the XB2 looks to be in stock at RC America. Hard arms all around, upper deck (in medium, looks like Hard is out), towers, C-hubs, steering blocks, rear uprights. Only thing notable as a spare that looks to be out almost everywhere is the rear inner hinge pin.

Does anyone use a different brand of o-ring in their gear diff? I am not having a lot of luck with the X ray ones.

Guess I'm looking for a little clarification here, Wiki post says he measured the same offset between AE wheels and Xray wheels on the rear but then he references spacers, looks like the front's require -.75 regardless so are the rear +3.75's required or not?
The rear gets complicated very quick. On a 2018 carpet with the stock +4.5 hexes if you run B6 wheels it ends up 2-3mm too narrow vs running xray wheels. Personally I liked this setup and never felt the need for extra spacers - before going to the new hubs.
With the launch of the carpet upgrade kit (for 2018c) the rear hubs have an adjustment that can increase track width. This also applies to the 19c kit. When I measured my 18 with this setup (hubs out as per 19c manual) or the 19c the rear was 2-3mm wider. I still ran B6 wheels and also liked this setup vs xray wheels. The only exception was if the track was not very tight with high speed corners the xray wheels added some stability.
Then we get to the 19 dirt car. This uses the xb4 arms and 3 slot +2.25 hexes. The overall width ends up being 2-3mm narrower than the stock 19 carpet version. I don't run on dirt but know narrower rear usually helps with traction.
Bottom line is try it and compare with your tires and track layout. Things I thought would be worse were often better than I expected.

The front is straight forward. It is about 1.5 wider than a B6.1. Therefore to match the B6 you would want -.75 hexes. However, on high grip carpet I have found I prefer B6 front wheels with the stock 0 hexes. In theory you should have less steering with the front wider but I found just the opposite. So make sure you try the 0 hexes before spending the money on -.75.
The rear gets complicated very quick. On a 2018 carpet with the stock +4.5 hexes if you run B6 wheels it ends up 2-3mm too narrow vs running xray wheels. Personally I liked this setup and never felt the need for extra spacers - before going to the new hubs.
