To provide optimal fit and performance for your specific vehicle, each TYC replacement mirror is identical in design and construction to the OE part they replace. TYC replacement mirrors feature a wide selection of old to newer vehicles everything produced meet all Federal SAE/DOT regulations and are FMVSS 111 compliant. Common issues with replacement mirrors are related to excessive vibration on rough roads, falling off after less than 1 year of use. TYC replacement mirrors are extensively tested against vibration on the glass, and are built to last, thanks to the strict standards within the ISO and TS certified manufacturing plants. All replacement mirrors are not created equal.
