Fab Fours Vengeance Bumpers for GMC Sierra 2500/3500

The GMC Sierra HD wears its own grille and lights, not the Silverado's, and the Fab Fours Vengeance front bumper is cut to fit that face. The rear is a different story. Back there the Sierra and the Silverado share one bed, so a single rear bumper serves both trucks. Both ends cover the 2011 models up to the newest HD, and a Duramax bolts to the same front as a gas truck. You choose the look, a bare nose or a pre-runner hoop, then order by your year. Fab Fours is the fourth-largest bumper maker in the aftermarket, and the Vengeance is its low, hard-edged line. Shipping is free in the US, and the fit is guaranteed to your truck.

The Front Bumper Is Cut for the Sierra's Face

Fab Fours cuts the Vengeance front for the Sierra's own front end, not the Silverado's. The two trucks wear different grilles and headlights, so the bumper is shaped to the GMC. Fab Fours calls the fit high and tight: it hugs the truck's lines, with a notch cut underneath for air and tire clearance.

Order by your year. There are four blocks: 2011-2014, 2015-2019, 2020-2023, and the newest trucks. GMC gave the HD a new face for 2024, a new grille, new lights, and a bigger front, so the 2024 and newer trucks take their own front bumper, apart from the 2020-2023 one. Pick the bumper for your exact year and it bolts to the factory mounts, whatever cab or bed you run.

The engine does not change the part. Fab Fours builds one front per block, with no separate diesel version, so a Duramax bolts on the same front bumper as a gas truck. From 2015 up, the front works with the factory parking sensors. The 2011-2014 trucks did not come with front sensors.

Each block comes two ways, and the difference is the look. The open front leaves the nose bare, a low bar with nothing above it. The pre-runner front adds a raised hoop across the center, which carries a 20-inch light bar and gives the truck a taller, harder stance. The open front weighs about 125 pounds, the pre-runner about 150. Both are the same 11-gauge steel under Fab Fours' two-stage black powder coat. Steel gauge counts down, so a smaller number means thicker plate, and 11-gauge runs a tenth of an inch and change. Want the clean, low nose? Take the open front. Running lights, or after a harder face? That is the pre-runner.

A winch is the one thing this front will not do. The Vengeance is the look-first line, so for a winch you move up to one of Fab Fours' heavier plate bumpers. Either front bolts to the frame on the included brackets, and most trucks need no drilling. The weight is what makes it a two-person job, not the wrench work.

Check your Sierra's platform years in the Silverado and Sierra HD fitment guide before you order the front.

The Rear Bumper Is Shared HD Steel

Out back, the Sierra HD and the Silverado HD are the same truck, so they take the same rear bumper. You will see a Chevy part number on it. That is right for your Sierra, since Fab Fours builds one rear for both trucks.

Three rears cover the years: one for 2011-2014, one for 2015-2019, and one for the 2020 and newer trucks. Each is 11-gauge steel at about 150 pounds. Each keeps the factory hitch receiver and trailer wiring, so towing is unchanged. Each side opens up for lights, with room for four cube lights or two 6-inch bars.

Blind-spot monitoring is the thing to check. The 2020 and newer rear supports it, but only on the 2020 to 2022 trucks. The 2015-2019 rear does not do blind-spot at all. All three keep your factory parking sensors. One more note: Fab Fours aims the sensor mount for a lifted truck, so a stock-height HD often needs the mount tuned to read right.

Frequently Asked Questions

Does the Vengeance front fit a Duramax Sierra HD, and will it hold a winch?

The Duramax fits. Fab Fours builds one front per year block, with no separate diesel version, so a Duramax bolts to the same front bumper as a gas truck. A winch does not. No Vengeance front carries a winch tray, since it is the look-first line. For a mounted winch, move up to one of Fab Fours' heavier plate bumpers.

The rear bumpers show a Chevy part number. Are they right for a GMC Sierra HD?

Yes. The Sierra HD and the Chevy Silverado HD share one bed, so Fab Fours builds a single Vengeance rear for both and lists it under a Chevy part number. It is the correct rear for your Sierra. The fronts are not shared, since the two trucks wear different faces, so order your front from this page. Driving the Silverado instead? The Fab Fours Vengeance for the Chevy Silverado 2500/3500 page has your front.

I run a stock-height Sierra HD. Will the parking sensors read right?

They can need a small adjustment. Fab Fours aims the sensor mounts for a lifted truck, so on a stock-height HD the mount often needs tuning for the sensors to read correctly. It is a known step, not a defect. Plan for it on both the front and rear bumpers if your truck sits at stock height.
