The short answer: The Leitner ACS FORGED is the best bed rack for the Toyota Tundra. It fits three generations of the truck, from 2001 through 2026, in every bed length Toyota has offered. Fitment splits by generation and bed length, and the 2022 and newer trucks get racks built specifically for the current composite bed. Three versions are available: Drill ($2,099), No-Drill ($1,999), and Tonneau ($1,950). Only the Drill version includes Leitner's patented sliding rear load bar.

The Tundra has been a full-size truck for a quarter century, and the current one is a different vehicle from the one before it in almost every way that matters to a rack. Here is what fits, what it holds, and what the composite bed on the newer trucks means for how a rack behaves.

Which ACS FORGED Fits My Tundra?

Start with your generation, then your bed length. The first generation is covered in one bed. The second generation is covered in three. The third generation is covered in two, because Toyota stopped offering the 8 ft bed with the 2022 redesign.

The 2022 and newer racks carry their own part numbers because they mount differently. Every third-generation Tundra has a factory mounting rail in the bed, the same kind Toyota builds into the Tacoma, and the Leitner rack bolts to that rail rather than clamping to the bed sides. The earlier trucks have no such rail, so their racks use clamps and share parts with other full-size trucks.

What Does the ACS FORGED Hold?

The same numbers apply whether you run the Drill or the No-Drill version. That is worth stating plainly, because plenty of clamp-on racks give up capacity in exchange for not putting holes in your bed.

Vehicle manufacturer load limits always govern. Where the truck's rating is lower than the rack's, the truck's rating applies.

The 4.0g figure is the one worth understanding. Most manufacturers publish a load rating without saying how they arrived at it. Leitner validates to 4.0g of force with a 400 pound load, which simulates what a loaded rack actually experiences on a washboard road at speed rather than what it can hold sitting still.

What the Composite Bed Means for a Rack

The 2022 and newer Tundra does not have a steel bed. Toyota molds the bed from composite, which is why it does not dent or rust the way steel does, and the D-pillars at the rear corners are cast aluminum rather than the steel used on earlier trucks.

That matters under load. A rack that clamps to the bed sides puts its force into the composite and the aluminum pillars, and on a heavy off-road hit with a loaded rack those parts can flex. That is a property of the truck, and it applies to any clamp-on rack on this bed. It is also why the Leitner rack for these trucks does not clamp. Toyota builds a factory mounting rail into every 2022 and newer Tundra bed, engineered for exactly this kind of load, and the ACS FORGED bolts to it. The rack ties into the structure Toyota designed to carry it rather than gripping the bed sides.

The 2007 to 2021 trucks have a conventional steel bed and steel pillars, and none of this applies to them.

What Is the Difference Between the Drill and No-Drill Versions?

Less than the names suggest. On the 2007 to 2021 trucks, both versions clamp to the bed rails without touching the bed itself, and neither one puts holes in your bed floor or your bed rails. On the 2022 and newer trucks, both versions bolt to the factory mounting rail.

The Drill version adds four holes total, two in each D-pillar, to accept nutserts. Those four holes are what allow the patented rear load bar to slide, which is how you load a motorcycle or anything else tall without unbolting the crossbar.

If you want the sliding load bar, you drill four holes. If you do not, the No-Drill version gives you the same mounts, the same capacity, and no holes anywhere. Load ratings are identical between the two.

How Hard Is the Install?

Leitner publishes one to two hours at an intermediate skill level for the no-drill install, meaning basic knowledge of hand tools. The rack is light enough for one person, though a second set of hands makes it easier.

A complete no-drill install uses 62 fasteners, roughly 40% fewer than comparable modular bed racks. The reason is hardware that does more per piece.

There are no loose flat washers in the kit. Leitner uses SEMS fasteners, which carry a captured washer on the bolt itself, paired with flange nuts on the other side. That removes two loose pieces from every joint. Competing kits ship dozens of separate washers.

Thread locker is already applied. Every fastener carries a dry thread locker patch rated for roughly 10 install cycles, so there is nothing to buy and nothing to wait on while it cures. Torque values are set for dry hardware to match.

The hardware is metric Torx. Metric sizing matches the fasteners already on your truck, and Torx resists cam-out better than hex under torque.

What Can You Mount on It?

The rack is built around a universal T-slot architecture, so accessories bolt on wherever you need them rather than only where a manufacturer drilled a hole.

The most useful addition for most owners is a GearPOD, a lockable storage box that mounts to the rack arms at eye level. That matters more on a full size truck than it does on a midsize, because the bed sides are taller and reaching over them for a tool is a genuine nuisance. With a GearPOD you are standing on the ground at chest height instead of climbing a tire to lean into the bed.

Rooftop tents, recovery gear, traction boards, fuel and water storage, lights, and antennas all mount to the same architecture.

Frequently Asked Questions

What bed rack fits a 2022 or newer Tundra?

The ACS FORGED, in a 5 ft 6 in or 6 ft 6 in bed version. The third-generation Tundra has its own part numbers because the rack bolts to the factory mounting rail in the bed rather than clamping to the bed sides.

Does the ACS FORGED fit a 2007 to 2021 Tundra?

Yes, in all three bed lengths. The second-generation Tundra has a steel bed and shares racks with other full-size trucks.

Does it fit a first-generation Tundra?

Yes. The 2001 to 2006 trucks are covered in the 6 ft 4 in bed.

Does the ACS FORGED fit a Tundra TRD Pro or Capstone?

Yes. Fitment depends on generation and bed length rather than trim, so TRD Pro, Capstone, and every other 2022 and newer trim take the same rack.

Will a bed rack damage the composite bed on a Tundra?

A rack that clamps to the bed sides puts its load into the composite bed and the cast aluminum D-pillars, and under hard off-road use with a heavy load those parts can flex. The ACS FORGED for 2022 and newer trucks avoids that by bolting to the factory mounting rail Toyota built into the bed, which is the structure designed to carry the load.

How much weight can a Tundra bed rack hold?

The ACS FORGED is rated at 1,400 lbs static, 800 lbs on-road, and 400 lbs off-road, validated to 4.0g of force with a 400 pound load. Your truck's own load limits still apply and govern where they are lower.

Do I need to drill my Tundra to install a bed rack?

Not with the No-Drill version. On 2007 to 2021 trucks it clamps to the bed rails, and on 2022 and newer trucks it bolts to the factory mounting rail. Either way it adds no holes. The Drill version adds four holes total, two in each D-pillar, for nutserts that let the rear load bar slide. Neither version puts holes in your bed floor.

How long does it take to install?

One to two hours at an intermediate skill level, using 62 fasteners for a complete no-drill install.

The Bottom Line

Three generations, six racks, and the only thing you need to know is which truck you have and how long the bed is. The newest trucks get racks that bolt to Toyota's own mounting rail instead of clamping to a composite bed, and every earlier Tundra is covered in whatever length Toyota sold.

The ACS FORGED holds 1,400 lbs parked and 400 lbs off-road, validated to 4.0g rather than calculated on paper, installs in one to two hours with 62 fasteners, and it is designed, engineered, and manufactured in Corona, California. All of it ships same day.
