Looking to build the ultimate handling Mustang? Steeda's adjustable rear sway bar should be part of your handling package!

Our adjustable rear sway bar is the ultimate upgrade for your 2005 and newer Mustang. It offers 3 positions of adjustment for fine tuning of handling balance. Starting with the softest position each adjustment position changes stiffness by 8% for a total fine tuning range of 16%.

Compared to the 2011 Mustang 7/8" sway bar our adjustable bar is 142% stiffer at the softest setting, 150% in the middle setting, and 158% at the stiffest setting. For vehicles equipped with a 1" rear bar our adjustable bar will provide an increases in stiffness of 67%, 75% and 83%.

Our adjustable rear sway bar can be used with the stock front sway bar or is a great complement to our adjustable front mustang sway bar for the ultimate in performance and tuneability.

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.

Note: Does not fit convertible.

Product Reviews

The install went great. The part fit perfect and was easy to install. This and the front bar really flattened out my car. It was so effective, I was able to losen up my struts and improve my daily driving. Great products!
