Fix the Rear Sway Bar Geometry on Your S550 Mustang
Whiteline’s rear sway bar end links for the 2015-2017 Ford Mustang (S550) are a direct replacement that addresses worn OEM link compliance and provides correct geometry for aftermarket rear sway bar setups. The S550 Mustang’s independent rear suspension responds directly to correct endlink geometry — worn or incorrectly-sized endlinks allow the rear bar to operate with preload, reducing its effectiveness.

S550 IRS — A Platform That Rewards Precision
The 2015-2017 Mustang’s independent rear suspension was a significant upgrade over the solid axle it replaced. The IRS is capable of delivering excellent handling when the geometry is correct and the bushings are in good condition. Correct endlink geometry is fundamental to getting the full performance from the rear sway bar.

Aftermarket Bar Compatibility
If you’ve upgraded to a Whiteline or aftermarket rear sway bar on your S550, correct endlink geometry is even more important. The new bar geometry may require different endlink positioning — these Whiteline units ensure the setup is correct for aftermarket bar applications.

S550 Mustang Track and Performance Use
The S550 Mustang is increasingly popular for road course and autocross use. Rear suspension precision is critical for consistent lap times, and correct sway bar geometry is a basic component of achieving that precision. Whiteline’s endlinks are part of a comprehensive S550 suspension package.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

A straightforward replacement that improves rear sway bar performance on the S550. If your Mustang has accumulated mileage or you’ve installed an aftermarket rear bar, these endlinks are worth doing. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
