Detailed Product Overview
Delphi TC4673 is engineered as a rear lower control arm for 2012-2021 Tesla S vehicles. The aluminum wishbone design uses rubber bushings to help maintain suspension geometry while isolating road vibration. Delphi applies dimensional and material analysis to match OE and aftermarket requirements, and the part is tested across extreme temperature ranges and extended salt spray exposure to verify durability in demanding conditions. This part cross-references Tesla 1021416-00-A and 1027459-99-A for the same application.
What This Part Helps Address
- Rear suspension looseness or instability
- Excessive play from worn control arm bushings
- Uneven tire wear related to rear suspension wear
- Noisy suspension movement from deteriorated arm components
- Restoring rear lower suspension geometry on Tesla S models
Installation Notes
Compatible With 2012-2021 Tesla S, rear lower. Bolt-in mounting simplifies replacement, but alignment should be checked after installation to confirm suspension geometry. Mounting hardware, cotter pin, and castle nut are not included.
Quality Assurance
Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio. TC4673 is evaluated for temperature extremes below -40 degrees C and above 120 degrees C, and it is exposed to 720 hours of salt spray to assess corrosion resistance and durability.
