Truck-Lite 97657 5.5x8.5-Inch Rectangular Black Stainless Steel Flat Mirror Head (Universal 5/16" Adjustable Ball Stud Mount)

Restore exact rearward clarity and protect your vehicle flanks with the heavy-duty performance of the Truck-Lite 97657 5.5x8.5-Inch Rectangular Flat Mirror Head. Specifically engineered as an ultra-reliable, medium-profile replacement head, this general-purpose flat-glass assembly is a favorite choice for parcel delivery vans, moving vehicles, box trucks, and vocational utility fleets. It ensures your medium-to-heavy-duty commercial equipment stays fully aligned with mandatory FMVSS 111 highway safety visibility standards.

Say goodbye to cheap plastic or painted frames that peel, scale, and crack over time. The 97657 features a premium, deep-drawn backing shell formed entirely from high-tensile stainless steel with a durable, matte black finish. This structural metal casing is engineered to withstand extreme over-the-road environments, harsh highway de-icing treatments, coastal humidity, and continuous flying road debris, keeping your vehicle looking sharp while maintaining premium structural integrity.

Optical precision is combined with smart engineering. The true-view flat-glass reflection surface delivers exact, undistorted distance tracking of oncoming traffic. To protect your line of sight on rough construction paths or bumpy urban streets, the high-clarity mirror plate is completely cradled and suspended within a soft, vibration-insulating continuous vinyl gasket seal. This heavy-duty rubber boundary acts as a defensive cushion against damaging chassis vibrations while effectively locking out moisture ingress to prevent premature glass clouding, pitting, or silvering degradation.

Installation is engineered to be quick, stress-free, and highly adjustable. Equipped with a universal 5/16-inch adjustable female threaded ball stud system (0.79 cm thread layout), this mirror head is tailored to fit seamlessly onto West Coast loops, standard door bracket arms, and rigid tripod fender bars.
