LEAVAN Rear View Wide-Angle Mirror for International 4300–8600 (2002–2023) — OE-Fit, Vibration-Resistant

LEAVAN’s Rear View Wide Angle Mirror is a direct OE-fit replacement mirror assembly engineered to match International 4300–8600 series trucks (2002–2023) and uses OE number 3686123C91.

This mirror assembly is built as a one-to-one replacement for the factory-installed lower side door mirror on a variety of International models, including Durastar, Workstar, Transtar, Prostar and Lonestar. Designed to meet SAE/DOT and FMVSS 108 standards, it combines a wide-angle glass element with durable housing and OE-compatible mounting so you can swap it in without modifying the door or drilling new holes.

How does this mirror restore visibility for heavy-duty International trucks?

The wide-angle lens expands lateral and rear coverage compared with standard flat glass, helping to reduce blind spots while changing lanes or maneuvering in tight yards. The glass and housing are built for truck duty cycles, resisting vibration and weather exposure.

• Wide-angle reflective surface for broader field of view
• OE glass shape and curvature comparable to original equipment
• Durable housing resists road spray and UV degradation
• Designed to maintain clarity under vibration and highway speeds
