Q: Will installing these coilovers void my Model Y warranty?

No, an aftermarket suspension kit alone does not void your Tesla warranty. Under the Magnuson-Moss Warranty Act, a manufacturer has to show that the part you installed actually caused the specific failure before denying that repair. Keep your factory parts so you can revert if needed. We back the coilovers with a 30-day money-back satisfaction guarantee, so you can take it off-road and then straight to work before deciding whether it stays on the car. Driving is believing.
