Recent 'Four Wheeler' mag article talks about the beefed up axle changes plus the new BW transfer case.
No matter which one of the four available engines are fit into the ’15 F-150, it’s mated to a 6R80 six-speed automatic transmission with a torque converter and tuning specific to its application. A new lighter-weight transfer case is also on tap and we’re told it’s a BorgWarner unit that was jointly developed with Ram trucks. Ford says the new T-case is 8 pounds lighter compared to the unit found in the previous truck. Depending on engine choice, most trucks get the 8.8-inch rear axle (referred to as the 8.8 Heavy). This axle has increased diameter axletubes and larger diameter axleshafts. A 9.75-inch rear axle is used in some applications. Up front, we’re told the IFS is basically carryover from the ’14 F-150. The rear suspension continues to be comprised of leaf springs, and the entire suspension has been retuned. Brake disc size and calipers are also the same as the previous model.
