⚠️ 2022–2024 SIERRA 1500 AT4 — CHECK YOUR GRILLE

Some 2022–2024 Sierra 1500 AT4 models come with a stacked horizontal bar grille (see photos below). If you have this grille, the light bar still installs — however, a significant portion of the light will be blocked by the grille bars, reducing your overall light output.

If you're okay with reduced output, you can absolutely still purchase and install. We just want you to know before ordering.

✅ AT4 with the standard open grille? You're all good — full light output, no issues.

Fits: 2019–2026 GMC Sierra 1500

Trims: PRO, SLE, Elevation, SLT, AT4, Refresh, and Denali. This will not fit Limited

How it installs:

  • Don't need to remove grille or bumper
  • The mounting bracket is on a rail system (see photo). This allows you to move the light bar up or down by about 6in. You choose where you want the light bar to shine through the grille
  • Only one (1) light bar PRO can be installed
  • Doesn't interfere with active grille shutters
  • Metal bracket is powder coated black
  • No cutting or drilling required. The kit is a complete bolt on using factory openings and hardware

👌M&R promises fitment of the light bars with the grille as pictured. If you have a different type of grille, please reach out with pictures for confirmation.

CHOOSE LIGHT OUTPUT COLOR

The PRO light bar uses a Combo Pattern, blending spot and driving optics for a balance between distance and width.

Every PRO bar is dual function — one off-road main beam that runs alongside an amber DRL (daytime running light) backglow.

Option 1 — White

Super bright, crisp white beam with plenty of light for any adventure. Off-road use only — the white beam blinds oncoming traffic and isn't street-legal.

Option 2 — Yellow

Cuts through dust, fog, snow, and rain far better than white light. Ideal for poor conditions. Off-road use only — the yellow beam blinds oncoming traffic and isn't street-legal.

Amber DRL — Both colors come with the same amber daytime running light backglow. Doesn't give off much light — just a bold amber glow that makes your vehicle stand out on the road.

BUILD QUALITY:

  • Uses a TIR (Total Internal Reflection) lens, which is different from the conventional optics parts, which lose some light internally and produce glare. The TIR lens collects all of the light from the LED and directly leads them to where you need, drastically reducing glare and improving total efficiency.
  • Higher light efficiency: brighter, longer irradiation distance
  • Housing is upgraded to 304 aluminum. The surface is UV polyester powder coated to protect against UV, salt water, corrosion, fading and scratch resistant.
  • Equipped with thermal management system that automatically adjusts the brightness output according to the external temperatures
  • Rated for a 50,000 hour lifespan
