Got power? If so, you need a rearend that can handle it. We used Auburn Gear, Precision Gear, Diff Works, and C&P to get our Ford moving.
From the Driver SeatSimply put, our truck was a pig off the line. It couldn't get out of its own way even when the throttle was held to the floor. With the new 4.10 gears and limited slip in place, the truck actually had some pep to it when leaving a stoplight. There were no more one-legged burn-outs, because the Auburn Gear limited slip grabs both axles once one tire gets more traction than the other. Don't get me wrong, this 250hp machine is not a drag car, but there is a noticeable difference when driving the truck hard. Also, at highway speeds, the transmission kicks down upon hard acceleration and holds the gear until redline-a feat that had all of us baffled. This mod was both fast and relatively inexpensive, which are characteristics we love around here. Are you wondering why your truck isn't running at its peak performance level? You may just need a new diff and ring and pinion swap to discover your rig's full potential.
