1985 Mustang Rear Axle

Rear Axle

The rear axle in your 1985 Mustang plays an important role in vehicle performance. It is in this area that engine power is transformed into wheel power, creating the palpable thrill you know as a drive in your 1985 Mustang. All 1985 Mustangs — aside from the SVO edition — came equipped with Ford’s 4 lug 28 spline rear axle. Ford’s Traction-Lok differential was an option that would cost buyers an additional $100 back in 1985. Since the rear axle plays such a big role in performance, Fox Body owners often choose to upgrade their 1985 Mustang rear axle in order to ensure their car reaches its full potential.

1985 Rear Axle

Why Upgrade Your 1985 Mustang Rear Axle?

There are many reasons a Mustang owner would want to upgrade their rear axle. The rear axle is where power is transferred from the engine to the wheels. If your modifications have increased horsepower, you should consider investing in a rear axle that can support that power. With more horsepower, you should always have more stopping power.

Consider upgrading from the stock 7.5” 28-spline 1985 Mustang rear end to an 8.8” 31-spline rear for greater power-handling ability and performance braking options. A larger rear axle can accommodate larger rear disc brakes. Swapping the 4-lug axle for the 5-lug axle also means more options for wheels and tires.

An upgraded rear axle paves the way for important performance upgrades such as:

• Larger Rear Disc Brakes
• Greater Ability to Handle Increased Horsepower
• Greater Variety of 5-Lug Wheel Options Available
