Hey everyone,

We're M&R Automotive, and we're excited to be part of the AT4 community!

We specialize in vehicle-specific LED lighting kits designed for trucks and SUVs that see everything from daily driving to overlanding and off-road adventures. Our goal is to build lighting solutions that look like they came from the factory while delivering serious performance when the sun goes down.

One of our newest products is the 2024–2026 GMC Sierra 2500HD/3500HD 40" PRO Light Bar Kit, designed to fit PRO, SLE, SLT, AT4, Denali, and Ultimate models. The kit mounts cleanly behind the grille with no cutting or drilling required and won't interfere with the factory active grille shutters. It's available with either a white or yellow main beam, both paired with an amber DRL backlight, and is backed by our lifetime warranty.

We're here to contribute, answer questions about lighting, fitment, wiring, and installations, and learn from fellow enthusiasts. If there's a product you'd like to see for your AT4 or you have questions about one of our kits, don't hesitate to ask.

Looking forward to getting to know everyone!

Mike and The M&R Automotive Team

Welcome.. how about a direct replacement fog light upgrade for the 2022.5 and up. I have a 2022.5 AT4x and there really are no good options to upgrade the stock fogs.
