Detailed Description

Built for rear upper suspension service, the Mevotech GS401180 trailing arm is a premium OE replacement for vehicles that rely on precise rear axle and suspension geometry. The steel arm and rubber bushings are selected to support controlled movement while helping maintain the ride characteristics expected in full-size Ford Panther-platform applications. This part cross-references Delphi TC6156 for the same application. The GS401180 is also referenced by Mevotech Original Grade GS401180 and Mevotech Supreme CMS401180.

Compatible With 1998-2011 Ford Crown Victoria, rear upper; 1998-2011 Mercury Grand Marquis, rear upper; 1998-2004 Lincoln Town Car, rear upper; and 2003-2004 Mercury Marauder, rear upper. If you are replacing a worn rear upper suspension trailing arm on a Ford Crown Victoria, Mercury Grand Marquis, or Lincoln Town Car, this part number GS401180 is built for that service position.

What It Helps Address

• Rear suspension looseness or instability
• Excessive movement from worn trailing arm bushings
• Clunks or noise from the rear suspension area
• Changes in rear axle location caused by worn OE components
• Ride quality concerns tied to degraded suspension control

Installation Notes and Tips

Verify rear upper position and vehicle application before installation. Inspect adjacent suspension bushings and mounting points for wear, since a new trailing arm can reveal other worn components in the rear suspension system. Torque fasteners to the vehicle manufacturer’s specifications after the suspension is at normal ride height when required by service procedure.

Quality Assurance

Mevotech supplies suspension components for OE-style replacement service, and this trailing arm is built with steel construction and rubber bushings to match the needs of the listed applications. Confirm fitment by year, make, model, and rear upper position before ordering GS401180.
