2015 Mustang Suspension


After much anticipation and plenty of mystery and suspense, the 2015 Ford Mustang is finally here! One of the biggest changes in the new 2015 Mustang is the transition from a live axle suspension, which has been a Mustang staple since the very beginning, to a new independent rear suspension. While this big change is expected to result in major ride and performance improvements, it's also going to result in dozens of new Mustang Suspension parts. CJ Pony Parts will have each of these new parts as they become available - just keep checking this page for the latest parts released from our vendors."

For nearly 50 years, the Ford Mustang has sported a live axle suspension. The live axle suspension features a solid beam that connects the left and right wheels. This means the movement of a wheel on one side of the vehicle impacts wheel movement on the other side. The type of suspension provided a relatively stable ride, especially when combined with a wide selection of aftermarket components that can helped with cornering, wheel hop and other problems that were common to this type of Mustang suspension.

Previous Issues With the Initial Mustang IRS

As part of a complete top to bottom redesign, Ford has designed the new 2015 Mustang to have an independent rear suspension. This is a first for any mass produced Mustang, though an IRS did have a problematic run in the Mustang Cobra nearly 15 years ago. Back then, the biggest issue was that that the chassis built for the New Edge SVT Cobra was not designed to accommodate the IRS. While Ford engineers attempted to overcome this obstacle by designing a special subframe to house the IRS assembly, the vehicle’s overall performance was significantly compromised.

How Does an IRS Work?

The way that an independent rear suspension works is that each wheel moves independently, instead of together with the other wheel on the axle. Unlike the live axle suspension where the beam connects the wheels on either side of the vehicle, independent suspensions feature shorter, more flexible drive shafts that transfer power to the wheels from the center differential.

In the case of an IRS, the power is transmitted to the rear wheels. The wheels are able to move up and down on their own — the movement of one wheel has no impact on the other.This movement provides a much more comfortable and stable ride versus a live axle.

The new IRS should improve the Mustang’s cornering ability and overall handling. An ancillary benefit is that it should make the new Mustang more attractive to buyers in the European market, where IRS systems have been standard features on sports coupes for many years. When combined with other engine and body modifications tailored to appeal to drivers on the other side of the Atlantic, Ford is hopeful that the IRS will help the 2015 Mustang increase its market share in the EU, as well as in the U.S. and other parts of the world.
