This all comes down to buy what you can afford, and be happy with your decision. Axles, gears, bearings, spools, yokes etc. all cost nearly the same from one rear to another. Now when it comes to weight and strength, that is where the $$$ comes into play. Want a cheaper rear? Install the Dana but accept the weight that goes along with it. BOTH are strong rears, and CAN get the job done.
