Detailed Description

This Mevotech lateral arm is built for the rear upper forward position on select Lexus vehicles, including the 2006-2015 Lexus IS250, 2006-2015 Lexus IS350, 2011-2014 Lexus IS F, 2007-2011 Lexus GS350, 2007-2011 Lexus GS450h, 2008-2011 Lexus GS460, 2006-2007 Lexus GS430, and 2006 Lexus GS300. The GS861051 part number is used in suspension repair where the original arm has worn bushings, loosened joints, or developed alignment-related issues.

As a lateral arm, this component helps locate the rear suspension and maintain the intended wheel position under load. The fixed-length, non-adjustable design matches the OE replacement format for the listed Lexus IS and GS applications, and the 10.88-inch length is an important specification for correct fitment in the rear upper forward location.

What It Helps Fix

• Rear suspension clunking or looseness from a worn lateral arm
• Uneven rear tire wear caused by suspension geometry changes
• Rear-end instability or wandering during driving
• Alignment issues related to worn suspension links
• Noise from deteriorated rear suspension components

Installation Notes and Tips

Verify the rear upper forward position before installation and confirm the vehicle application by year, model, and suspension layout. Because this arm is non-adjustable, final alignment should be checked after installation to confirm rear suspension settings are within specification. Compare the original arm length and mounting points to the GS861051 before assembly.

Quality Assurance

Mevotech Original Grade part GS861051 is an OE replacement suspension component for the listed Lexus applications. This part cross-references Delphi TC7299 for the same application.
