The gears in the diffs have never been an issue. Nobody has ever stripped out the plastic gears. You can't even compare the xb4 to a d413. The 413 is a sloppy mess! You should have gotten the yz4 to compare to the xb4. IMO no wheeler comes close to how well the xb4 performs. Now your going to need to get a xb2 while your at it.
