Keep the front stabilizer bar securely located and cushioned with the Mevotech Supreme Sway Bar Bushing Kit MS504121. These front-to-frame bushings wrap the stabilizer bar where it mounts to the frame, damping vibration and helping the bar work as intended when you turn or ride over bumps. It installs as a direct-fit replacement for the 2010-2016 Buick LaCrosse, 2014-2020 Chevrolet Impala, and 2014-2015 Chevrolet Impala Limited — see the Buyer's Guide tab for engine-level details.

  • High durability: built with high-grade natural rubber construction for strength and long service.
  • Precision engineered: shaped to replace the original bushings on the listed applications.
  • Quick, easy installation: the slit design lets each bushing slip onto the stabilizer bar for fast fitment.
  • Rigorously tested: validated through extensive in-house and third-party durability testing.

If worn front stabilizer bar bushings are the cause of clunking, rattling, or a loose feel during cornering, this kit replaces them front to frame.

What does the Mevotech Supreme MS504121 kit do?

It supplies replacement front-to-frame stabilizer bar bushings that cushion and locate the front sway bar where it mounts to the frame, helping the bar control body roll as designed.

Is this the same as a stabilizer bar bushing kit?

What are signs the sway bar bushings may need replacing?

Clunking or rattling from the front, or a loose feel when cornering or crossing bumps, can indicate worn bushings. Diagnose the cause before replacing, as other parts can produce similar symptoms.
