I consider the spindles a weak point. But for what its worth I have a fair bit of mileage off road with the Raptor and so far my stockers are doing just fine. The thing that concerns me about the Alpha 1s is the welding. Sheet metal onto cast steel... IMHO that requires nickle 99 wire, proper preheating and cooling down of the cast, and specialized techniques only those experienced with this exact type of weld can properly apply. Do it wrong or miss a step and you've taken an already acknowledged weak point, and you've made it far, far weaker than what you started with. Or to put it another way... I have two very experienced and well educated welders on my staff, and neither feels confident enough to do this job for me. That tells me everything I need to know. Your mileage will most certainly vary.
