My son is wearing out axles on his DRR. About one a race. He is a bigger 10 year old and the skinny aftermarket axles for the DRR aren't cutting it. Heard people doing the 300ex and cobra axle bearing housing, carrier and axle swap. Which one is best and what parts do I need to do it with? I have a Dave Carter swingarm now with stock DRR bearing carrier and both of the different brand after market axles made for it, not doing a name drop here cause I am not happy with their product lol. Thanks in advance!
