Delphi TC8506 Lateral Arm - Rear Upper Forward

Delphi TC8506 Rear Upper Forward Lateral Arm

Delphi TC8506 is a rear upper forward lateral arm built for precise suspension location and OE-style replacement performance. It is engineered for the 2016-2021 Tesla X and uses forged aluminum construction with rubber bushings for controlled movement and consistent alignment support.

Delphi applies OE-level dimensional and material analysis to help ensure proper fit and dependable suspension operation. This Delphi TC8506 lateral arm is a direct replacement for the rear upper forward position on Tesla X models and is built to handle demanding temperature and corrosion testing standards.

Detailed Description

The Delphi TC8506 lateral arm is designed for the rear upper forward suspension position on Tesla X vehicles from 2016 through 2021. Its forged aluminum body helps provide the strength and dimensional stability needed in a suspension control component, while the included rubber bushings support controlled articulation and road isolation. Delphi’s OE-focused engineering approach emphasizes material accuracy and compatibility with the original suspension layout.

This part cross-references Mevotech Supreme CMS95139 for the same application. If you are replacing a worn rear suspension arm on a Tesla X, the TC8506 offers a direct-fit solution for restoring proper suspension geometry and rear-end stability.

What This Part Helps Address

• Clunking or knocking from the rear suspension
• Excessive play in the rear upper forward arm
• Uneven tire wear caused by suspension looseness
• Alignment issues related to worn suspension bushings
• Reduced rear suspension control and stability

Installation Notes and Tips

Install the Delphi TC8506 in the rear upper forward position only on confirmed Tesla X applications. Because this arm is non-adjustable, final alignment should be checked after installation. Inspect adjacent suspension components, fasteners, and mounting points for wear before completing the repair.

Quality Assurance

Delphi subjects its OE-style steering and suspension components to extreme temperature and corrosion testing, including sub-zero and high-heat exposure as well as extended salt-spray testing. The brand also uses dimensional and material analysis to support fitment consistency between OE and aftermarket parts.
