Project Sinatra was about to receive some added street performance by simply adding a Precision Gear 4.10 ring and pinion set to help the F-150 launch harder than ever before. A major must when swapping gears is the replacement of the old hardware. We ordered a Precision Gear overhaul kit that included new axle bearings, a pinion bearing, seals, bolts, and a differential gasket.
