Fitment guarantee and VIN verification

Every part undergoes strict quality control before shipping.

Fitment / installation note: The cable channel with index A represents an earlier production revision of the windshield component in the MLBevo platform. Using the original OEM guide eliminates vibrations, looseness, and windshield noise, and completely removes the risk of the wiring harness chafing against the wiper mechanism. Before purchasing, we recommend comparing the full catalog number with the index (A) stamped on the old part or verifying fitment using the vehicle's VIN.
