Keep your 2015-2023 Mustang's suspension geometry in check after it has been lowered with a new Bump Steer Kit (555-8133) from Steeda! Once you have lowered your Mustang, bumpsteer will be increased and must be corrected to help eliminate any unwanted driving characteristics. Steeda's bump steer kit will allow you to correct your bump steer geometry without requiring you to drill or modify your brand new Mustang's spindles.

Bump steer is the change of toe during suspension movement. When you turn your steering wheel you are essentially changing the toe of the wheels to turn the vehicle. Every vehicle has bumpsteer, it is just more noticeable for lowered vehicles. Excessive bump steer is undesirable because it introduces unwanted steering inputs causing the suspension to steer the car instead of the driver.

- Wide Range of Adjustment
- Does NOT Require Any Spindle Modifications
- Compatible with ALL Models
- Direct Bolt-In Replacement Install
- High Quality Construction
- Superb Fit and Finish
- Made in the USA

Please Note: Does NOT fit any Shelby model Mustangs. Will not clear any 16" wheels or the OE 17" wheels found on some 2015+ Mustangs.

Tech Tip: CJ Pony Parts highly recommends getting an alignment after installation to ensure your Mustang's specs are in check.

Every car has bump steer, however when you lower your Mustang you will increase the amount of bumpsteer that occurs. When you turn your steering wheel you are essentially changing the toe of the wheels to turn the vehicle. With excessive bump steer, you will begin to notice some unwanted vehicle driving characteristics. Pick up a bump steer kit today and strengthen your outer tie rods and improve the steering feel of your S550 Mustang.

If you've ever driven a lowered car, down a bumpy road, you're probably familiar with bump steer. Bump steer's going to occur when suspension movement causes changes in the toe which can cause the car to unexpectedly change direction. If you own a 2015 Mustang, Steeda's adjustable bump steer kit, is an excellent way to fix this issue. Today we're going to install these, on Yassen’s2015 Mustang GT.

The Steeda Bump Steer Kit's going to be a direct replacement for the outer tie rod ends on all 2015 Mustangs. By maneuvering the different spacers in here, will allow us to get the angle just right. To avoid bump steer on our lowered Mustang. Because of the spacers, this will work on any stock, or up to two to three inch lowered car. For this installation, we need a lift, or a jack and jack stands. Half inch ratchet, 18 millimeter socket, 19 millimeter socket, 24 millimeter socket. Torque wrench, hammer, and adjustable wrenches.

The bump steer kit's going to replace your outer tie rod by threading on right here. First step to the installation, is to loosen this jam nut on the factory tie rod end. Basically what you want to do, is just it loose. Turn it back a hair, from the factory tie rod, then it's no longer touchable. Okay, with that loose, now you can remove the retaining nut that holds the outer tie rod in to our spindle. Now you want to unthread the factory tie rod end. Should be loose, but if not, you can pull the inner here, take it off that way.

Now you're going to thread the retaining nut down, 3/16ths of an inch. Now thread the aluminum collar from our bump steer kit, up until it hits the jam nut. On the bearing side, you can thread it onto the collar. This is going to be a reverse thread. Then you want to tighten everything down. Now we're going to install the stud with the spacers, through our spindle.

What you want to do is align it with the lower control arm. Get them as close to parallel as possible. You're just going to guess at this point with the spacers. The alignment shop will help to make the final adjustments, when you get it aligned, after you're finished your installation. You can see, we have it pretty much parallel with our lower control arm. Like I said, you can move these spacers around. Get it as close as possible. We've found that putting the three on the top, and the two on the bottom, seems to get it in the neighborhood.

Again like I said, when you get it aligned after the installation, the alignment shop can dial it in. First we'll tighten them down, and then we're going to torque them down. The bottom nut's going to get torqued to 50 foot pound. Forty foot pound for the top. Repeat the process on the other side, and your installation is finished.

The Steeda Bump Steer Kit's the perfect way to address any bump steer issues we may have, in our lowered 2015 Mustang. Make sure, when this installation is finished, you do have to get an alignment. This is imperative, when installing this, to get the car to track properly. The installation itself, should take you around an hour. You should back on the road in no time.
