Motive Gear 04-07 5.4L F-150 9.75" Gear Set (4.10 Ratio)
Ring and Pinion gears are the differential's critical point of power transfer. Ring and Pinion gears are probably the simplest performance modification one can do to a vehicle.
The most common reason to change Ring and Pinion ratios from the original equipment is to keep your power when bigger tires are put on a vehicle. You can easily increase torque with a ratio change for greater pulling or take off power from a dead start. People from off road enthusiasts, competitors, recreational trailer boaters, farmers, and everyday motorists will find quality and selection surpassed by none at Motive Gear.
