1967 Differentials
Most 1967 Mustang’s came standard with an open rear end. The open design evenly distributes power and torque to each wheel. It also allows the wheels to rotate at different speeds, allowing the vehicle to turn easily.
This design limits the torque applied to each wheel based on the amount of power needed by the wheel with the least resistance. That’s why if you do a burnout in a vehicle with an open rear end, one tire spins wildly burning rubber, while the other tire may appear to be stationary. Each wheel is receiving power equally based on the wheel that has the least resistance.
Open vs Limited-Slip Differentials
A limited-slip 1967 Mustang differential, or Equa-Lock, as Ford called it, was an option for select Mustangs. It was even standard equipment on the 1967 GT. The limited-slip differential allows both wheels to turn freely, but if one wheel starts slipping and encounters less resistance than the other, power is then redistributed to where you need it most — the wheel that has the most resistance or traction.
If you’re thinking of upgrading your 1967 Ford Mustang rear axle, you may want to upgrade to a limited-slip differential. If you like your existing 1967 Mustang differential, but feel like power hasn't been reaching your rear wheels, then you may want to opt for a drop-in replacement or rebuild your existing differential. We have options for both.
