Q: Does adding this suspension kit void my Tesla warranty?

Installing it does not automatically void your Tesla coverage. Under the Magnuson-Moss Warranty Act, Tesla would have to show that a specific failure was caused by the aftermarket part before denying that claim, not simply point to the fact that you modified the car. Keep your factory shocks and springs so you can revert if needed. Unplugged Performance also backs its parts and installations with a 2-year, 24,000-mile warranty on materials and workmanship.
