Wich axel is the best for me?

Trick question. If you dont do suspension upgrades and run fat sticky tires an 8.25 will work or the 8.8, Put some bite down and fat sticky tires and youll need the 8.75 or a 9 inch.Four link it with slicks and the Dana 60 may be the ticket. Theres a lot more to it than motor size.
