Dial in precise rear-suspension alignment with the Mevotech Supreme Alignment Cam Bolt Kit MS500191. This rear cam bolt kit installs as a direct-fit alignment component for many vehicles, among them the 2010-2018 Buick LaCrosse, 2013-2018 Cadillac XTS, and 2011-2017 Buick Regal — see the "Vehicles it fits" section for the full list.
An eccentric cam bolt replaces or supplements the factory hardware so a technician can shift the suspension geometry during a wheel alignment, helping correct settings that can contribute to uneven rear tire wear and poor tracking when they fall out of specification.
- Rear position: cataloged for the rear suspension on the listed applications.
- Toe adjustment range: Toe ±2.0°, giving the alignment tech room to bring the rear toe back into the factory range.
- Cam bolt design: the eccentric (offset) cam rotates to move the suspension point, locking in the corrected angle once torqued.
If your rear alignment reads out of specification and worn or missing adjustment hardware is the cause, this kit is designed to provide the adjustment needed to set it correctly. Have the alignment performed by a qualified technician after installation.
