Factory 3.54:1 gears are a little tall for the 35-inch tires, but the rear Dana 60 can easily support the big Mickeys. Lift blocks were used to partially gain the lift in the rear, and they were degreed slightly to improve pinion angle, compensating for the lift. Rotating the pinion upward is usually necessary when a lift of more than 2 inches has been installed on a vehicle. A lift moves the axlehousing away from the transfer case, which in turn increases the driveshaft angle. The U-joints at each end of the driveshaft aren’t designed to work beyond a certain angle, so axlehousings are rotated upward to return the U-joint angles to stock.
