Application: 2015-2018 Mustang Ecoboost, V6, and GT

Bushing Lubrication.
The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.

How’s it going guys? Landan here with LMR.com! This video will cover my product breakdown and installation on Steeda’s front sway bar fitting the 2015 to 2018 Mustangs.

Here at Late Model Restoration, taking corners at speed is by far one of our favorite things to do during our spare time. Because of that, stronger aftermarket sway bars are usually one of the first upgrades we do to our cars.

For our 2018 Mustang GT shop car we chose Steeda’s aftermarket front sway bar for several reasons. For one, Steeda’s quality and craftsmanship is second to none, and the fit and finish is always spot on.

Now, this front sway bar from Steeda is going to be larger than the factory unit measuring in at 38mm in diatmeter which also equates to an inch and three-eighths. This will allow for reduced body roll, improved handling, and more stability when cornering.

Steeda designs and manufacturers each sway bar in-house from the highest quality materials. This sway bar features billet steel ends versus the coined ends found on other offerings.

What does this mean? This means that the sway bar ends are machined from billet steel round stock on a multi-axis CNC lathe, and then go through hundreds of computer simulations to ensure the ultimate in strength and performance.

This sway bar is designed to fit 2015 to 2018 V6, EcoBoost and GT Mustangs. In the box will be a front sway bar, poly urethane bushings and bushing brackets. The factory retaining bolts will be reused. This sway bar sold by itself or in a kit with Steeda’s rear sway bar.

To get things started, support the car via a lift or jack stands.

Remove both front wheels.

Now, remove the sway bar end link from the sway bar.

Use a 17mm open end wrench on the stud and an 18mm deep socket on the nut.

Slide the end link out of the sway bar.

Do this for the other side.

Locate the two the sway bar mounting brackets attached to the top of the k-member.

All but one of these bolts will be removed from the engine bay.

To make some room, disconnect the MAF sensor connection and remove the push pin from the air box.

Loosen the 7mm hose clamp securing the inlet elbow to the air box.

Slide the inlet elbow off of the air box.

Remove the 10mm air box retaining bolt from the fender.

Now you can remove the air box from the car.

On the driver side frame rail, remove the plastic push pin securing the brake lines.

Go ahead and remove the two push pins securing the plastic alternator shield from the frame rail.

Set the shield aside.

On the passenger side, use an assortment of extensions and an 18mm wobble socket to remove both bolts securing the sway bar bracket.

Once loosened, you can fetch the bolts from within the wheel well opening.

On the driver side, loosen and remove the frontward bolt.

Because of the alternator placement, you’ll have to remove the rearward bolt with a ratcheting wrench from within the wheel well opening.

The two brackets are attached to the sway bar, so no need to remove those.

With the assistance from a friend, remove the sway bar from the car.

Most people have success with removing this from the driver side, but me personally; I find it easiest to pass the sway bar out from the passenger side.

Taking a closer look at the attachment points on the sway bar ends; you’ll find four holes to choose from.

The hole furthest to the end of the bar will provide the softest setting.

Each hole leading back towards the bar itself will net a firmer setting; with the hole closest to the front of the car resulting in the stiffest setting.

Before installing the Steeda sway bar into the car, liberally lubricate the inside of the two provided bushings with the provided grease.

Position them over the sway bar and on the inside of the bushing stop.

Now, go ahead and install the Steeda sway bar into the car in the same location and orientation as the factory bar.

On the driver side, lubricate the top of the k-member where the bushing will make contact with the provided grease.

Lubricate the inside of the provided bracket and then position it over the bushing.

Align the mounting holes and loosely tighten the two factory bolts.

Repeat these steps for the passenger side bushing and bracket.

Go ahead and torque the four factory bolts to 35 to 40 lb-ft.

Reposition the factory alternator shield, reinstall the push pins, and the push pin securing the brake lines to the frame rail.

Reinstall the air box back into the car.

Connect the MAF sensor, tighten the 7mm hose clamp, and then reinstall the 10mm retaining bolt.

Because our car will see several open track events, I’m installing the end link in the second hole from the front of the car.

This will set the car up with an aggressive stiffness.

Once the end link is in position, rethread the nut and then torque to 65 lb-ft.

Do the same for the other side and make sure the end link is in the same position on the sway bar end.

Reinstall the front wheels and then double check your work.

Get the car on the ground, take it for a test drive, and then you’re all finished.

Alright guys, I would recommend the assistance from a buddy when installing this front sway bar. It isn’t difficult by any means, but an extra set of hands wouldn’t hurt to get the job done.

All in all here fellas, this a great sway bar for daily driven Mustangs and even better for those of you that auto cross or road race your car.
