Q: Will replacing my front control arms void the Model X warranty?

Fitting these does not automatically void your Tesla warranty. Under the Magnuson-Moss Warranty Act, Tesla must prove the arms caused a specific failure before denying a related claim, and these are full OEM-spec replacements engineered to maintain proper suspension geometry. To sharpen the rear of the car to match, owners often add the Pikes Peak Spec rear sealed spherical bushing kit. Keeping your original arms lets you revert if needed.
