How to Install a Sway Bars on Your S650 Mustang

If your 2024+ Ford Mustang isn't cornering as sharply as you'd like, upgrading your factory sway bars and replacing them with an aftermarket set can reduce body roll in corners and improve stability. All S650 Mustangs come equipped from the factory with sway bars, but many enthusiasts decide to upgrade them before doing any high-performance driving or tracking.

How to Install Adjustable Sway Bars on a 2024-2025 Mustang

This step-by-step installation guide will walk you through the removal of the stock front and rear sway bars and the installation of the new, adjustable sway bars. While this guide and video were made for the 2024 Mustang, the process is similar for all S650 Mustangs. In the video above, we chose a set of RTR adjustable coilovers that comes with the necessary grease for installation.

Tools and Supplies Needed:

• 10mm Socket
• 13mm Socket
• 18mm Socket
• 18mm Wrench
• Floor Jack
• Jack Stands
• Grease (included in kit)
• Disposable Rubber Gloves

Step 1: Loosen Front Sway Bar End Links

Use an 18mm wrench to loosen and remove the front sway bar end link on the driver's side. Then, do the same on the passenger's side.

Step 2: Remove Sway Bar End Link from Sway Bar

Separate the sway bar end link from the sway bar by using a pry tool to carefully pop the end link out of place.

Repeat that process on the other side.

Step 3: Loosen Back Sway Bar Bolt

Use an 18mm wrench to loosen and remove the back bolt on the front sway bar on one side.

Repeat that process on the other side.

Pop the hood and locate the dual air intakes at the front of the engine bay.

Step 7: Disconnect MAF Sensor

Pop the intake cover off and locate the mass air flow sensor. Then, disconnect the mass air flow sensor by pulling back on the white tab and separating the connector from the intake.

Then, use a pry tool or clip removal tool to pop the wiring harness clip off of the intake.

Step 8: Remove the Intakes

After you've disconnected everything, remove the intakes from the engine bay.

Pull the sway bar out of the Mustang from the front wheel well. If possible, have a helper or friend push from the opposite side to get it out easier.

Step 12: Slide New Front Sway Bar Into Place

Carefully slide your new front sway bar into place through the front wheel well. If possible, leave the shipping wrap on the sway bar to prevent it from getting scratched during installation.

Step 13: Grease Sway Bar Bushings

Using the supplied grease in the kit, apply grease to the inside of the sway bar bushings until sufficiently covered.

Remember to grease both the driver's and passenger's side bushings.

Step 14: Install Front Sway Bar Bushings

Insert the greased front sway bar bushings into place on the new sway bar.

Step 15: Install Sway Bar Mounting Brackets

From the engine bay, install the sway bar mounting brackets with the factory hardware.

Step 16: Reinstall Sway Bar End Links

Locate the mounting hole on the sway bar and reconnect the sway bar end link, but don't tighten everything down. Once you've reconnected the sway bar on the opposite as well, then go back and tighten both sides to spec.

Step 17: Reinstall Air Boxes and Intakes

Go back into the engine bay and reinstall your air boxes and intakes before moving onto the rear sway bar.

Step 18: Remove Rear Sway Bar End Link Bolt

Move to the rear of the car and access the rear wheel well. Then, remove the 10mm bolt holding the sway bar end link in place on both sides.

Step 19: Disconnect Sway Bar End Link

Loosen and remove the sway bar end links from the factory sway bar. Then, set them aside for later.

Then, slide the bushings into place on the new rear sway bar.

Step 24: Slide Rear Sway Bar Into Place

Carefully slide the new rear sway bar into place on the rear of the car.

Step 25: Reinstall Factory Mounting Brackets

Reinstall the factory sway bar mounting brackets and hardware to secure the new rear sway bar in place.
