Detailed Description

Delphi TC4595 is a rear upper rearward lateral arm designed for 2017-2022 Tesla Model 3 and 2020-2022 Tesla Model Y vehicles. Built from steel with a tubular shape, this arm uses rubber bushings and a painted black finish to match the demands of everyday suspension service. Delphi applies OE-style engineering and extensive dimensional and material analysis to help ensure the replacement part aligns with the original suspension layout. This part cross-references Mevotech Supreme CMS95141 for the same application.

Common Issues This Part Can Address

• Excessive rear suspension play from worn arm bushings
• Clunking or knocking from the rear upper suspension area
• Uneven rear tire wear caused by worn suspension geometry components
• Loose or unstable rear-end handling over bumps and turns
• Corrosion or fatigue in the original lateral arm assembly

Installation Notes and Tips

• Verify the rear upper rearward position before installation.
• Inspect adjacent bushings, mounting points, and related suspension hardware for wear.
• Confirm mounting hole diameter and arm length against the original part before service.
• Professional alignment is recommended after suspension component replacement.
• Use the vehicle-specific fitment data for Tesla Model 3 and Tesla Model Y before ordering.

Quality Assurance

Delphi tests suspension components across extreme temperature ranges and salt-spray exposure to evaluate durability and OE-level performance characteristics. The brand also uses dimensional and material analysis to support fitment consistency between original and replacement parts. Part number TC4595 is built to meet standard replacement expectations for the listed Tesla applications.
