Ford Mustang Differentials

After the engine and transmission, the Mustang differential is the last part before the wheels can turn. Here's how it works: At the end of the driveshaft, there is the input pinion, which turns the ring gear in your Mustang differential. The ring gear is attached to the cage, which spins the side gears, which spins the two half axles. However, your Mustang differential only works like this when driving straight.

Once you begin to make a turn, the additional gears inside the cage of your Mustang differential, the pinion gears, must begin to spin to compensate for the differing speeds of your wheels as they go around the turn. In this basic form, this type of Mustang differential is called an open differential. This Mustang differential system works beautifully on dry roads, but what happens if your Mustang begins to slip a little, like in rain?

To combat this, most Mustangs have a limited slip differential, many of which are available from CJ Pony Parts. This type of Mustang differential uses a spring pack and clutches to limit the torque to the wheel that is slipping. This makes sure that the wheel getting traction still has the torque it needs to move, while the clutches in the Mustang differential harness the torque to the other wheel, preventing it from spinning.

Some newer Mustangs use a Torsen differential, which doesn't have any clutches. Instead, this Mustang differential works exactly like an open differential on dry roads. However, as soon as one wheel starts to slip, the difference in torque causes the gears to bind together. This gear design determines the torque bias ratio, which shows how much more torque gets applied to the wheel that's gripping. This type of Mustang differential is often used in high performance applications, which is why CJ Pony Parts offers it for newer GTs and GT500s. It's also standard on the new Boss 302 Laguna Seca.
