2001 Ford F150

Superchargers, nitrous, intakes, and exhausts are all great power adders; but if the power goes up in smoke, the effort and money spent were all for not. When rebuilding our F-150 SuperCrew, named Project Sinatra, we knew power would be a large area of concern. Sending the power to our truck was going to be an Auburn Gear High Performance limited slip unit, with a Precision Gears 4.10 ring and pinion bolted to it, and cooled by a Concept Pattern (C&P) differential cover. With our nearly 32-inch tall 24-inch wheel and tire combo on the Ford, the 4.10 gears will help us to get out of the holes much faster. Meanwhile, the Auburn Gear High Performance limited slip will ensure the extra added power will actually motivate the truck into a forward line. The key is to start with a trusted shop and quality parts when swapping gears and a differential in your truck, and so we contacted the pros over at Diff Works in Riverside, California, to perform the install. Known for its complete axle kits, Diff Works wasted no time tearing into the 6-year-old truck and had us back on the road before lunch. Lifted, lowered, or even stock with some bolt-on power adders, your truck can benefit from a new set of gears and a high-performance differential.
