No, no typo, the guy I bought it from said what gears were installed, I did the tire test, and the Driveshaft does spin three and a half times per one tire turn.. I thought all came with these gears from the factory unless the originally purchaser bought the package to have the tighter gears in the rear?
It also runs very nicely on the hwy with no over reving witch I would assume it would do if it did have 4.10s in the rear with the original 3 speed, but it doesn't.
