• Non-adjustable layout for straightforward installation
• Black finish for a clean, corrosion-conscious appearance

Detailed Description

Dorman 527-502 lateral arm is built as a direct replacement for the original equipment design on supported Ford and Lincoln vehicles. The arm uses a casting/forged style construction with bushings at both ends, a pressed attachment type, and a 12.2 mm mounting hole diameter to match the specified suspension application. Part number 527-502 is listed for rear right upper fitment on 2015-2025 Ford Mustang, 2015-2024 Ford Edge, 2019-2023 Lincoln Nautilus, 2017-2020 Lincoln Continental, and 2016-2018 Lincoln MKX.

This part cross-references Monroe Shocks & Struts (e.g., FR3Z5500C, CMS401212) for the same application. If you are replacing a worn lateral arm on a Ford Mustang or Ford Edge, 527-502 provides the OE-style geometry needed to restore suspension alignment and control. The rubber bushings, steel body, and standard replacement grade make it a practical choice for service work where the original arm has loosened, worn, or developed noise.

What It Is Used For

• Correcting suspension looseness caused by worn arm bushings
• Addressing clunks or squeaks from a deteriorated lateral arm
• Restoring rear suspension geometry after component wear
• Replacing a bent or damaged lateral arm assembly
• Supporting proper wheel control in rear suspension service

Installation Notes and Tips

Verify the rear right upper position and match the vehicle year, make, and model before installation. This arm is not adjustable and does not include mounting hardware, so confirm the existing fasteners and related suspension components are serviceable before beginning the repair. Part number 527-502 should be compared against the removed component and fitment listing for the exact application.

Quality Assurance

Dorman states that this lateral arm is precision-engineered and rigorously tested for reliable replacement of the original equipment part on specific vehicles. The standard replacement design is intended to meet the needs of routine suspension repair with the correct fit and function.
