Steeda's popular S550 front and rear sway bar kit is now paired up with our adjustable endlinks in one combo it with even greater savings!

Steeda has the track-proven sway bar and endlink combination that will give you reduced body roll, adjustability, and the best handling of any sway bar package out on the market!

This kit will provide an increase in front and rear roll stiffness for a balanced handling package.

Our press-fit welded billet ends are far stronger than stamping the end of the bar. Billet machining construction of the Steeda Mustang Front and Rear Sway Bar ends makes for far greater strength for a bulletproof sway bar.

Our sway bars have machined steel billet sway bar ends, whereas others on the market have coined ends. What does this mean? Our sway bar ends are machined out of billet steel round stock, in-house, on our multi-axis CNC lathes and go through hundreds of computer simulations to ensure the ultimate in strength and performance - this provides greater resistance to bending stresses, and has three major advantages:
  • These parts are less prone to cracking/fatigue failure on the ends themselves.
  • It also reduces unwanted deflection in the sway bar end. Excess deflection creates unwanted geometry changes, which physically changes your sway bar stiffness to a non-ideal rate.
  • With less unwanted deflection, our bars will 'wear out' slower - any spring will eventually become softer over time as it is cycled through its life, our bars will maintain their designed rate for longer with less unwanted deflection.

Our bar rates are developed and optimized through advanced vehicle dynamic simulation and through extensive real-world testing. We engineered these bars to control the vehicles' roll stiffness properly while still allowing you to run softer springs. This optimizes your overall grip and balance of the vehicle while still allowing you to maintain exceptional ride quality.

Steeda's adjustable stay-bar endlinks make a great upgrade for the stock endlinks as well as the perfect dual purpose street/open track piece. For street applications these endlinks are as quiet as the factory units. They will not add NVH (noise, vibration, harshness) like rod end units.

Note: Front Sway bar will fit vehicles equipped with MagneRide Suspension but cannot be used at softest setting due to contact with factory ride height sensor.

Great adjustable stiffness
This product is great. I have a PP1. These sway bars are much thicker and stiffer then them. You can definitely feel a difference in cornering and just making normal turns. I like that you can also adjust how stiff you want to make them for the track or normal street driving.

Absolute Game Changer
First of all, these things are 99% worth the buy. I daily drive a 2017 Mustang GT. These add ons will completely change the way your vehicle handles in turns. While going down a long ramp onto the highway I frequent, I could hold a solid 40 mph before starting to pucker up. With the new equipment I can confidently take it at 60mph before I start to get that little bit of pucker factor now. The car feels like it is on rails now the way it corners. I had the bars with billet mounts and adjustable endlinks installed at a local shop. Only reason for the 4 stars instead of 5 is that there is significantly more noise in hard turns (even while moving slowly through parking lots) due to the replacement of the rubber from the factory. Probably going to need to invest in a grease gun and some silicone spray, and climb under the car every few months to help reduce noise.

Must have item
I own a 5.0 performance package. That feeling of floating while driving goes away with the sway bars. This is a must have set up. I took it to the track over the weekend and my car just hugged every corner. Do not hesitate to buy this. This combined with steedas pro action struts is a match made in heaven. Thanks again steeda and sponsor me :-)
