high speed rear axle

Post by rocky miller »

thinking about buying a high speed rear axle for my 31 AA Just curious as to how much faster it will allow to run? Currently 25-30 mph is top speed. Thanks for any information on this topic.

I have a stock high speed rear end in my 31 AA. But I also have 650x20 tires on my truck. It will cruise along about 45mph comfortably. Stock engine, points, etc.
