does anybody know how the 3rd's out of the toyota dually's measure up to the 3rd's out of V6's or 4cyl's? i'd figure they'd be bretty strong. anybody know?!?

 

i mean pretty strong. lol considering you could be putting a TON of weight under that rear.

 

As far as I know, they are the same basic 8" 3rd like the 4WD trucks get. Could be a V6/4 pinion version. Axle strength on the duallys comes from the full floating design. You have the vehicle weight supported by a spindle and double wheel bearings (like on the front axle) and the torque from the 3rd is the only thing in the axle shaft.

 

makes sense. thanks crawler.
