Prothane 99-04 Ford Mustang Cobra IRS Diff Bushings - Black

In this kit, you get the black Prothane differential bushings designed to fit the 1999-2004 Ford Mustang Cobra's Independent Rear Suspension (IRS). These are meant to replace the original rubber bushings that locate the differential housing. Over time, the stock bushings can wear out, leading to unwanted movement in the rear end.

Prothane uses a specially formulated polyurethane material for these bushings. This material is known for being durable and resistant to the common fluids found under a car, like grease and oil. By installing these, you're looking to get a more solid feel from the rear of your Mustang, which can help with better power delivery to the wheels and more predictable handling, especially when you're driving it hard.

Replacing these bushings is a common job when you're looking to firm up the rear suspension on your Cobra. It's a good idea to check the condition of your differential mounts and related hardware while you're in there.
