Rear Eibach Swaybar for 1999-2004 Mustang Cobra with IRS.

Includes the rear swaybar and rear pivot bushings. Endlinks not included.

This rear swaybar is an excellent choice when fine-tuning the handling of your IRS-equipped Mustang, your current front swaybar is already optimized, and you just need a little larger rear swaybar to help balance the handling.

Installing good swaybars is one of the best, most affordable things you can do to make your Mustang handle! Swaybars do all of this:

  • Reduce body roll during cornering
  • Speed up turn-in response
  • Improve the handling balance

This swaybar kit includes:

  • Rear Swaybar
  • Urethane pivot bushings
  • Grease

  • Rear: 29mm Tubular, 2-way adjustable

What's in a name?
Here at MM we call these products "swaybars," but some people call them "anti-roll bars" or "anti-sway bars." These are all just different names for the same hardware. We prefer "swaybar" to avoid confusion with the safety device called a "roll bar," while "anti-sway bar" is just needlessly lengthy.


  • Eibach swaybars are manufactured from precision-made, high-tensile steel alloy that is cold-formed, tempered, and shot-peened for long-lasting performance and durability.
  • Finished with a long-lasting red powdercoat.
  • Eibach swaybars come complete with urethane bushings for improved responsiveness, and mounting hardware (when appropriate for the application).
  • Includes instructions for easy installation.

Eibach uses world-renowned German CNC machines, along with their own proprietary machines, to work the special cold-formed, high-strength, aircraft-grade steel that contributes to their products' precision performance. But it's not just about machines and technology. Eibach workers at production plants in the USA and Germany are talented, expert craftspeople, each committed to creating the finest race- and street-performance parts possible. MM engineers and test drivers believe in their quality, so you can, too!
