I requested the suspension upgrade at the Tesla Service center through the app and I gave them the following upgrade numbers.
DAMPER ASSEMBLYCOIL E3 - DUALMOTOR - FRONT LEFTHAND(1188363-00-H)
DAMPER ASSEMBLYCOIL E3 - DUALMOTOR - FRONTRIGHT HAND(1188368-00-H)
SPRING, REAR, COIL90.0-7200(1188474-00-C)
SPRING, REAR, COIL90.0-7200(1188474-00-C)
DAMPER ASSEMBLYCOIL - DUAL MOTOR -REAR(1188463-00-E)
DAMPER ASSEMBLYCOIL - DUAL MOTOR -REAR(1188463-00-E)
They then sent me an estimate and the incuded part numbers were -
DAMPER ASSEMBLYCOIL E3 - DUALMOTOR - FRONT LEFT HAND(1188363-00-F)
DAMPER ASSEMBLYCOIL E3 - DUALMOTOR - FRONT RIGHT HAND(1188368-00-F)
SPRING, REAR, COIL90.0-7200(1188474-00-C)
SPRING, REAR, COIL90.0-7200(1188474-00-C)
DAMPER ASSEMBLYCOIL - DUAL MOTOR -REAR(1188463-00-E)
DAMPER ASSEMBLYCOIL - DUAL MOTOR -REAR(1188463-00-E)
I noticed the revision number on the front left and front Right part number end with an F instead of an H. (1188363-00-F)
I went into the Service center and they told me that the revision letter of F doesn't mean much but he assured me that the part number he gave me is definately the suspension on the 2023 Model Y and he went to the service department to double check. Does this sound correct? With every forum that I research and find all users say they were upgraded with the H part number (1188363-00-H). I want to make sure that they are not installing the same old harsh 2021 suspension. Does anyone have any knowledge of the revision letters?
