Suspensia X56LA0685 Suspension Control Arm - Rear Left Upper

OE-Style Suspension Control Arm

Suspensia X56LA0685 is a rear left upper suspension control arm built for direct OE fit and OE appearance. It is engineered for select Buick and Cadillac applications and uses a steel construction with rubber bushings for a service-ready replacement.

Key Features

• Direct OE fit and OE look for straightforward replacement.
• Steel construction for structural strength in suspension service.
• Rubber bushings included for controlled articulation and isolation.
• Non-greaseable design with no grease fitting, dust boot, or ball joint included.
• Suspensia chassis parts are produced in an IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 50001:2018 certified facility.

Detailed Description

This suspension control arm is designed for rear left upper mounting positions on 2017-2019 Buick LaCrosse, 2018-2020 Buick Regal Sportback, 2018-2020 Buick Regal TourX, 2021-2024 Buick Envision, and 2019-2024 Cadillac XT4. The X56LA0685 uses a steel body with black rubber bushings and a regular-grade construction, making it a direct replacement option for restoring suspension geometry and bushing support. Suspensia positions this part within its OE-style chassis line, and the X56LA0685 reflects that focus on fit, appearance, and manufacturing consistency.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn or damaged rear left upper control arm.
• Addressing looseness or play in the suspension linkage.
• Restoring proper suspension arm support and alignment behavior.
• Reducing noise caused by deteriorated bushings.
• Correcting handling issues related to suspension wear.

Installation Notes and Tips

Verify the rear left upper position and confirm vehicle application before installation. Inspect adjacent suspension components, fasteners, and alignment settings during service. Because this control arm does not include a ball joint, grease fitting, cotter pin, castle nut, or lock nut, transfer or source any required related components separately as needed for the application.

Quality Assurance

Suspensia manufactures chassis parts in a highly automated OE-focused facility and backs production with multiple international quality and environmental certifications, including IATF 16949:2016 and ISO 9001:2015.
