Re: rear differential question

Guys, keep in mind, the truck 12 bolt will NOT take the same power a car 12 bolt will stand up to. It's all in the pinion shaft diameter. If you make big HP with good traction in a heavy vehicle, they are known for shearing the pinion shaft off.

The 3.5% extra power loss is a bit of hyperbole as well. The deeper off set of the pinion gear does create more "wipe" against the ring, but it also increases contact patch, which makes it stronger. Not to mention the 3 bearings on the pinion vs 2.....
