Detailed Description

Mevotech CMS861051 is a rear suspension lateral arm for Lexus IS250, Lexus IS350, Lexus IS F, and select GS-series vehicles. The fixed-length design and corrosion-resistant finish make it a straightforward replacement for the rear upper forward location, including applications that connect to the strut rod. This part cross-references Beck/Arnley 102-7328 and Delphi TC7299 for the same application.

Common Repair Applications

• Rear suspension noise from worn arm bushings or joints
• Uneven rear tire wear related to suspension geometry
• Loose or unstable rear-end handling
• Excess movement in the rear upper forward suspension link
• Restoring proper alignment on Lexus IS250, IS350, and GS models

Installation Notes and Tips

Verify the rear upper forward position and confirm vehicle year, model, and suspension configuration before installation. Because this arm is not adjustable, final alignment should be checked after replacement to confirm rear suspension geometry is within specification. Compare the original part dimensions and mounting points to CMS861051 before service.

Quality Assurance

Mevotech suspension components are built for replacement use in OE-style applications, with corrosion-resistant finishing to support long-term service in exposed underbody locations.
