Product Description

Tighten Up Your Suspension
If you want to get your S550's suspension tightened up and performing like a track car, this 2015-2018 Mustang Steeda front and rear sway bar kit is the solution! These billet machined sway bars replaces your factory bars for a stronger, more reliable setup. Included in this kit is (1) front sway bar, (1) rear sway bar, and a set of new sway bar bushings. They feature press-fit welded billet ends that are far stronger than stamped ends. These 2015-2018 Mustang sway bars have been designed, manufactured, and tested by Steeda here in the USA. Pair them up with a set of lowering springs to get the ultimate suspension setup on your S550!

- Fits 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.

    5 Stars   Great Sway Bars LMR.com Expert Review!
    By on 12/1/2017
    As a road racing enthusiast, I wanted my 2018 Mustang GT with Performance Pack to have the absolute best handling characteristics it could have.

    Even with the Performance Pack option, there was still a lot of room for improvement which is why I chose these sway bar package from Steeda.

    Both the front and rear Steeda sway bars are larger than the factory pieces which provide better handling, reduced body roll, and better stability when cornering.

    Installation of these sway bars is very easy, and you'll want an extra hand when installing the front.

    These sway bars made a BIG difference to my 2018 Mustang GT, and I would recommend this package to any 2015-2018 owner!

    Yes, I would recommend this item to a friend!

    5 Stars   excellent upgrade even the wife likes!

    My 2015 GT Premium with the 20" wheel/tire package. non-PP (auto transmission) needed a little help in the handling department. These bars really solved the somewhat sloppy handing issue very well. The install is not very easy, so I opted to have my local speedshop do the install and the cost was only about $180. The car now has a lot less body roll and, of course, sway bars do not change the ride at all so my wife was really happy and that is, as most of us know first hand, is a necessity for future additions. Highly recommended.

    Yes, I would recommend this item to a friend!
