Mustangs come stock with a steel driveshaft, which is durable but heavy. Replacing your steel driveshaft with an aluminum one reduces your drivetrain’s rotating mass. Even minor weight reduction can improve your acceleration.

Though aluminum is lightweight, it’s still durable. That’s why aluminum driveshafts are so popular with performance Mustang owners. Aluminum driveshafts are especially popular with drag racers, but every Mustang can benefit.

Many aftermarket driveshafts are also one-piece instead of the two-piece stock driveshafts. These one-piece driveshafts are popular for several reasons. First, they often weigh less than a two-piece. They also lack a central connection point, which is a place where some power is lost. Due to their construction, there are fewer parts that can break as well. And drivers have noted that their car feels more responsive after making the switch.

Changing out your driveshaft is often necessary when upgrading your engine or transmission. There’s no reason to wait for a major equipment swap to change your driveshaft though. Cutting weight without sacrificing durability makes aluminum driveshafts an easy choice.
