GMC MultiPro Tailgate: All 6 Functions & How It Works

The GMC MultiPro Tailgate is one of the most genuinely useful innovations in the full-size truck segment. Most tailgates do one thing: they drop down to give you access to the bed. The MultiPro does six, each designed for a specific situation you actually encounter when you own and work a truck. Whether you are loading cargo, setting up a worksite, helping someone climb in, or hosting a tailgate party, there is a configuration designed for it. This guide explains all six positions, covers the optional Kicker audio system that turns the tailgate into a speaker, lists which GMC models include it, and compares it directly to Ram’s competing multifunction tailgate.

What Is the GMC MultiPro Tailgate?

The MultiPro Tailgate is GMC’s proprietary six-function tailgate available on Sierra 1500 and Sierra HD trucks. It replaced the standard drop-down tailgate on equipped models and uses a two-panel design in which the top portion folds down independently of the lower portion, and each panel can be configured in multiple ways to suit the task at hand. The design was introduced on the Sierra 1500 in 2019 and has been refined in subsequent model years, with the current version adding the integrated Kicker audio system on select trims.

Unlike a standard tailgate that is either up or down, the MultiPro operates more like a piece of equipment than a door. Once you understand what it can do, the single-position tailgate on a competitor’s truck starts to feel like a limitation. Understanding all six positions takes about ten minutes with the truck on the lot, and after that initial orientation, the functions become second nature.

Across every position, the MultiPro is counterbalanced and damped: it opens and closes with one hand and lowers under control rather than slamming down. If you open the tailgate dozens of times a week, that is a meaningful difference on its own, but it is how the gate operates rather than one of its six functions.

The 6 MultiPro Tailgate Positions Explained

1. Primary Gate Load Stop

With the primary gate down, the inner gate’s panel unlatches and folds upright to form a vertical barrier. It keeps long items that overhang the bed, plywood, paddleboards, a dirt bike, from sliding out under braking, without restricting access to the bed.

2. Easy Access

Lowering the inner gate while the primary gate is down brings you roughly 7 to 9 inches closer to the bed floor than a conventional tailgate. That shortens the reach every single time you load or unload from the back.

3. Full-Width Step

With both gates lowered, the inner panel folds down into a step 48 inches wide and rated for 375 pounds, and a hand grab folds out from the cargo box wall to steady you on the way in. This is GMC’s answer to the high bed floor on a modern full-size truck, with no separate bed step accessory required.

4. Inner Gate Load Stop

Lowering the inner gate and unfolding its inside panel creates a vertical load stop for longer items carried in the upper tier of a two-tier bed load.

5. Inner Gate Work Surface

Lowering only the inner gate leaves a flat surface at workbench height: somewhere to cut a piece of trim, write up a quote, or lay out tools. Combined with the available 120-volt bed outlet, it turns the back of the truck into a genuine worksite station.

6. Outdoor Audio

The MultiPro Audio system by Kicker, built into the inner panel, which turns the tailgate into an exterior sound system.

MultiPro Audio by Kicker: The Built-In Tailgate Speakers

Select Sierra trims offer the MultiPro Tailgate with integrated Kicker audio, a speaker system built into the tailgate itself. This option turns the tailgate into a sound system for outdoor use, a feature that has no equivalent on any competitor’s truck as a factory-installed option.

The Kicker system is a 100-watt setup with two 4-inch coaxial speakers built into the inner panel, a compact amplifier with its own controls, a USB charging port, and Bluetooth streaming. Its wiring, connectors, speakers and plugs are weather resistant for the outdoor environments where trucks actually get used. The most practical detail: the system runs independently of the truck, so the engine does not need to be running, and a tilt switch shuts it off automatically when the inner gate is folded and the tailgate is closed.

In practice, the MultiPro Audio by Kicker is purpose-built for tailgate events, job site background music, camping, and any situation where you want audio outside the cabin. The sound quality from a factory-installed system inside a tailgate exceeds what most portable Bluetooth speakers deliver, and the integration with the truck’s own electronics means it works with whatever source you are already playing through the infotainment, including Apple CarPlay, Android Auto, and satellite radio.

For Florida Sierra owners who spend time at outdoor events, the beach, or hosting gatherings in their driveway, the MultiPro Audio adds an entertainment capability that no other truck offers from the factory. There is no setup involved, no portable speaker to charge and the audio plays outward through the gate. The Kicker speakers are also positioned below ear level when the tailgate is open, which means the sound projects toward the group rather than upward into the air, a real-world advantage over mounting a speaker on the roof or truck bed wall.

Which GMC Models Offer the MultiPro Tailgate

MultiPro vs a Standard Tailgate vs Ram’s Multifunction Tailgate

Ram’s competing tailgate offers a useful swing-out step function and a traditional fold-down mode, making it a two-in-one design. The MultiPro’s six positions give it a more complete range of configurations, and the integrated Kicker audio is not available on Ram in any factory configuration. For buyers who use their truck as a worksite tool and need flexibility in how they access and contain cargo, the MultiPro’s load stop and cargo stop positions address use cases that Ram’s design does not cover. For buyers who prioritize the step function and are satisfied with that single additional feature, Ram’s design is simpler to operate.

Real-World Uses: When Each MultiPro Position Actually Helps

Knowing the six positions is one thing; knowing which situation calls for which position is where the MultiPro becomes a daily tool rather than a showroom feature. Here is how typical Sierra owners use each mode.

Contractors who load lumber and sheet goods daily use the load stop position to keep materials from shifting during transport, eliminating the need for bungee cords or bed nets to prevent sliding. Landscapers who pull heavy debris with rakes and shovels from the back of the bed use the inner gate step to climb in and out without putting strain on knees or requiring a running board they would prefer not to trip over on a worksite. Boaters and outdoor recreation users who load gear into the bed from a trailer hitch or ramp find the cargo stop position keeps equipment from rolling back out as they work at the tailgate.

For Florida residents who tailgate at games, outdoor concerts, or sporting events, the Kicker audio position, tailgate fully open with speakers facing the crowd, turns the Sierra into a sound system that does not require setting up a separate speaker on the truck bed. The combination of the GMC’s infotainment system and the outward-facing Kicker speakers is genuinely capable for a group of a dozen people gathered around the back of a truck.

See the MultiPro Tailgate in Person at Starling GMC St. Cloud

The MultiPro Tailgate is one of those features that makes much more sense in person than in a description. Starling GMC St. Cloud has Sierra 1500 models on the lot with the MultiPro Tailgate, including configurations with the Kicker audio system. Ask any of our sales consultants to walk you through all six positions during your test drive. Once you see how each mode works in practice, the value of having all six positions becomes immediately clear.

If you are configuring a new Sierra 1500 and want the MultiPro with Kicker audio, the Kicker system is standard on the AT4X and Denali Ultimate, and our parts department can add it to other trims. Talk to our team about which trim level fits your needs and budget.

The MultiPro Tailgate is also one of those features that buyers rarely regret choosing, even if they were unsure about it before purchase. Once you have used the step to climb into the bed, the load stop to secure a sliding piece of equipment, or the cargo stop to keep groceries from falling out while you load the rest, the six-position design stops feeling like a technology feature and starts feeling like the obvious way a tailgate should work. For buyers who are cross-shopping Sierra 1500 against F-150 or Ram 1500 and are unsure whether the MultiPro justifies any potential price difference, we recommend asking a Starling GMC St. Cloud consultant to walk you through it in person before you decide.

Conclusion

The GMC MultiPro Tailgate brings six distinct configurations to a part of the truck that was previously a single-function panel. The load stop, cargo stop, step, and full inner gate positions each solve a real problem that truck owners encounter regularly, and the counterbalanced EZ-Lift operation makes the gate easier to use than any standard tailgate regardless of which mode you choose. With optional Kicker audio on upper Sierra 1500 trims, it also doubles as an outdoor speaker system that no competitor offers from the factory. If you are cross-shopping Sierra 1500 against F-150 or Ram 1500, the MultiPro Tailgate is one of the most tangible functional advantages the Sierra brings to that comparison.

Frequently Asked Questions

Does the MultiPro Tailgate work with a tonneau cover?

Yes, but compatibility depends on the specific cover. Most roll-up and folding tonneau covers are compatible with the MultiPro Tailgate because they attach to the bed rail rather than the tailgate itself. Hinged hard covers may limit some MultiPro positions. Check with your accessory installer before purchasing a cover if MultiPro function in all six positions is important to you.

Can the MultiPro Tailgate be added to a Sierra that did not come with it?

No. The MultiPro Tailgate requires specific structural support and wiring built into the truck at the factory. It cannot be retrofitted to a Sierra that came with a standard tailgate.

Is the Kicker audio system waterproof?

The system is weather-resistant and designed for outdoor use. GMC and Kicker rate it for typical outdoor conditions including rain. It should not be submerged or exposed to pressure washing aimed directly at the speaker grilles.

Does the MultiPro Tailgate add to the truck’s towing capacity?

No. The MultiPro Tailgate does not affect towing ratings. Towing capacity on the Sierra 1500 is determined by engine, rear axle ratio, and trailering package selection, not the tailgate option.
