Kraton Kraton exb damaged outdrive cups

[dk3000]

Hey guys by chance anyone have any ideas as to why these outdrive cups keep getting damaged? I'm just trying to check and make sure it's not something I've done wrong. This is on the front btw. Maybe other Kraton owners have had this issue. Thanks

Remove the lower Pivot ball washers/ shims if they are there. And the pins will seat inboard more. May help.

But honestly, it looks like User error/ abuse, and/or a powerful drivetrain would cause this. (ESC/Motor). Look into M2C diff output drive cups. A bit more hardened. I run 6s and never had this type of wear on any of my 6s rigs. The normally wear out, but not mangled like yours.

Looks like normal wear and tear, especially when the driveshafts pop out.

It was me running it hard but I've noticed wear before the issue got this bad. And I'm running the 8s setup on 6s so it definitely is a power horse. I'll be ordering m2c most defensive over the arrma exb ones. Also turning punch down from 5 as well.

It's your shafts trying to pop out that is making those chips. take both the top and bottom washers off on the ends of the a arms on both sides of the car. It will allow the shafts to seat further in the cups and stop that chiping. Rpm arms are common for this too. Just remove the washers and your good to go.

It’s common on the EXB. Get the M2C outdrives instead.

Fastest wearing part on all cars. When a rc vehicle company figures out how to stop that wear,iam a buyer. Also like the ones with enclosed pinion an spur gears so no worries there too.

+1 looks like normal wear and tear to me as well, my exb is starting to show early signs of looking like that

Had the shafts pop out a couple of times which doesn't help
