Gentex introduced the GNTX‑R, a slim‑profile carbon‑fiber auto‑dimming rear‑view mirror, at the SEMA 2025 trade show in Las Vegas. The mirror uses Gentex’s proprietary electrochromic gel, integrated sensors, and a microprocessor to provide rapid dimming and precise glare control for high‑performance vehicles.
The GNTX‑R is aimed at the custom‑car aftermarket, available in red or black with a frameless design. Gentex will sell the mirror through Ringbrothers’ online parts store, with first‑quarter 2026 availability.
The launch marks Gentex’s first direct entry into the aftermarket segment, expanding beyond its core OEM business. The partnership with Ringbrothers, a well‑known custom‑car builder, underscores the company’s intent to tap a niche market that often commands higher margins.
Gentex also showcased other automotive technologies at SEMA, including car‑to‑home automation, connectivity, digital vision, and dimmable glass products, highlighting its broader technological capabilities.
