Are these extended hubs any good?

I was looking at them and they are much cheaper than axles, but are these extended hubs any good. Because my bro told me about one guy that bent his axle from spacers. I am going to jump my blaster.

You'll need new rear wheels, those have a bigger bolt pattern than the Blaster.

i think the same company makes the extended blaster hubs too
