first off this is my dd and the only wheeling it sees is mud on occasion, (once a monthish). The biggest tires this truck would ever see are 35s or 36s. My buddys dad has a wrecked k5 that has d44front and 10b rear they both have lockers, Eaton rear, and a factory front . IM unaware of the gear ration but as long as its above 3.08 i may buy these. he said hed sell both for 400...i laughed the front axles pinion is broke (driveshaft thingy) bc when the truck wrecked, he went off the road and landed in a ditch on his nose. Thus snapping one of the rings. What would you pay and would you do it?
