BAKFlip G2 Review: The Cheaper BAK If You Rarely Open the Bed

Buy the BAKFlip G2 if you want BAK's fold-to-the-cab hard cover and you open the bed a few times a week, not a few times a day. At that pace it's the BAK we'd pick. The catch is the tailgate. With the cover shut, you lift the rear panel, close the gate, then drop the panel so it latches. The MX4 skips that step, and the tailgate is the main thing its extra money buys, along with a higher load rating and a longer warranty. On water, the G2 looks no leakier than the MX4, which we rate high for leak risk, though the evidence behind that is thinner than we'd like.

The G2 has been on sale a long time, so there's plenty of owner history, and plenty of owners have bought a BAK more than once. Much of that history is on older trucks. The complaints are specific: the tailgate routine, thin aluminum that dents in hail, a heavy fold, and the drop brackets that put Toyota deck rails back after the install.

The short version

What works:

• Full bed access: the same fold-to-the-cab design as the MX4. Fold the panels forward, secure them, and drive with the bed open. The listing says it doesn't cover the third brake light.
• Water: most owners describe a dry bed or a few drips, which reads better than the MX4's record.
• Price: it cost less than the MX4 on every same-truck, same-bed listing pair we compared on Amazon.
• Install: clamp-on with no drilling, which RealTruck says takes 30 minutes or less on most trucks.

What to watch:

• The tailgate step: you lift the rear panel before you close the tailgate. On weekends it's nothing. If you're in the bed all day, it gets old fast.
• Lower ratings: 300 lb evenly distributed and a 3-year warranty, against the MX4's 400 lb and 5 years.
• Dents and weight: hail dents the thin aluminum skins, and the cover is heavy to fold back to the window.
• Toyota deck rails: the rails go back in on drop brackets, and those brackets bend if you ratchet-strap a load to them.

Which trucks and beds it fits

BAK sells one G2 part number per truck and bed, and Amazon lists them the same way. We confirmed the fitments below on each listing's own product page; the table under the score panel has the part numbers and bed lengths in inches.

• F-150: the 14th-generation F-150 (Gen14, 2021-2026, including Raptor and Lightning) has 5 ft 7 in and 8 ft 2 in listings. The Gen13 (2015-2020) has 5 ft 7 in, 6 ft 7 in and 8 ft 2 in listings. RealTruck also lists a Gen14 6 ft 7 in part (226337) that we didn't confirm on Amazon. RealTruck's G2 page says nothing about Ford's BoxLink, so ask before you order if your bed has it.
• Silverado and Sierra 1500 (T1XX): short-bed (2019-2025), 6 ft 7 in and 8 ft 2 in (2019-2026) listings, all of which say they work with the MultiPro and Multi-Flex tailgates. The short-bed listing won't fit the CarbonPro composite bed. Amazon calls the short box 5 ft 10 in; RealTruck calls the same part the 5 ft 8 in bed.
• Ram 1500 (DT): the tailgate decides it. The 5 ft 7 in (2019-2026) and 6 ft 4 in listings we confirmed don't fit the multifunction split tailgate, and a separate 5 ft 7 in listing (2020-2026) does. RealTruck sells a RamBox part (226227RB) that we didn't find on Amazon. Amazon also carries G2 listings that read 2002-2023 Ram 1500 and 2003-2021 2500/3500; the DT has its own parts above, so we've left those out of the table.
• Tacoma: the 4th gen (2024-2026) has a confirmed 5 ft listing, which RealTruck lists for trucks with the deck rail system. RealTruck also lists a 4th gen 6 ft 2 in part and 3rd gen (2016-2023) parts for the 5 ft 1 in and 6 ft 2 in beds, none of which we confirmed on Amazon. Check fit for your truck with the search link in the picks.
• Tundra: a confirmed 3rd gen (2022-2026) 5 ft 7 in listing. RealTruck lists a 6 ft 7 in part as well.
• Maverick, Colorado/Canyon and Ranger: the Maverick listing reads 2021-2026 with a 4 ft 6 in bed, while RealTruck lists the same part for 2022-2026 and calls it the 4 ft 4 in bed; the truck itself started in 2022. The 2023-2026 Colorado and Canyon have a 5 ft 2 in listing. RealTruck lists a 2024-2025 Ranger part we didn't confirm on Amazon, and a separate part for the 2026-2027 Ranger. Don't move a cover between them: a 2024 Ranger's G2 didn't fit its owner's 2026, because the bed rails changed a little. Buy the part listed for your model year.

On a Tacoma, RealTruck's own article on deck rails says you'll take the rails off during the install and put them back on drop brackets. Those brackets bend under a ratchet strap, so read the durability section before you count on the rails for heavy tie-downs.

The specs that matter

RealTruck rates the G2 at 300 lb evenly distributed and backs it with a 3-year limited warranty for the original buyer, which doesn't transfer. It describes solid-core panels with aircraft-grade aluminum skins under a semi-gloss black powder coat (the spec table on the same page says gloss black), EPDM rubber perimeter seals and an integrated drainage system, without saying how the water leaves the bed. Automatic slam latches lock each panel as it closes, so the bed is locked when the tailgate is. The Amazon listing adds quick-release cables under the panels so you can open it from either side, and prop rods that hold it upright. RealTruck doesn't publish the cover's weight.

Here's the G2 against BAK's own MX4 and RealTruck's two UnderCover hard folders, from RealTruck's product pages and, where those are silent, the Amazon listings:

All four are hard folders that clamp on with no drilling on most trucks, per RealTruck, and none has a published weight. Over the G2, the MX4's extra money buys 100 lb more rating, two more years of warranty and a tailgate you don't have to work around. The Ultra Flex gets you the same upgrades plus a fold that stands clear of the cab, and the Armor Flex adds a coated top.

The 300 lb figure means weight spread across the whole closed cover. It isn't a rating for someone kneeling on one panel or a loaded cooler sitting on a seam, and RealTruck publishes no point-load figure for either BAK. The warranty gap is easier to put in real terms. Keep a truck five years and the MX4's warranty covers all five. The G2's runs out after year three.

Folded, the G2 stacks against the cab, right behind the rear window. Expect to lose much of your view out the back on haul days; folded up for a big load, BAK's similar FiberMax blocks it entirely. Plan on your mirrors.

Telling the BAKFlips apart

BAK's hard folders look alike, and used listings mix them up, so know which one you're looking at. The G2 has the gloss finish, a 300 lb rating and a 3-year warranty. The MX4 has a textured matte finish, aluminum panels over high-density polymer cores, a 400 lb rating, a 5-year warranty and a dual-action tailgate seal that lets the tailgate close with the cover down; RealTruck says the current Gen 3 seal is 13 percent longer than before. RealTruck's warranty terms give the F1 five years like the MX4 and the FiberMax three years like the G2. A cover sold as just a "Bakflip" could be any of them, so ask for the model before you pay.

Weather sealing and leaks

We'd call the G2 no leakier than the MX4, and possibly drier. Most G2 beds stay dry or see a few drips. A Gen14 F-150 cover two-plus years in is, in its owner's words, not fully waterproof but waterproof enough, which is a fair description of any hard folder. The worst case is a used cover on a 2016 Canyon that leaked badly enough for a seal replacement project.

Hold that loosely. There aren't many reports about the G2 alone, and a lot of them are years old. Some buyers also pick the G2 because they've read about MX4 leaks, and that alone doesn't make it drier.

When water does get in, it comes at the cab end or through tired seals. A Tacoma G2 gets a few drips at the front corner by the cab, sealed with silicone, and the rest of the bed stays dry; the Tacoma's plastic bed rails make any cover harder to seal, which is why that owner traded the factory cover for one they could seal. The Canyon had a new bulkhead seal by the cab and still leaked, partly through side seals along the rails whose ridges had worn down, and it was missing a clamp on the driver's side. Nobody names a trigger like heavy rain or car washes, and there's too little here to rank the leak points.

Start with the clamps: they may be in the wrong spots or loose, and resetting them is the first fix to try. Then the seals. Replacement side seals for the G2 can be hard to find, so a bead of silicone as a stand-in ridge, or MX4 seals, are fallbacks worth weighing. Check that the cover sits square, too; a crooked one can be straightened. We rate leak risk moderate, as the cover arrives: five of the six G2-only reports describe little or no water, one describes a real leak, and there are fewer reports than we'd like.

Build quality and living with it

We'd expect a G2 to last. It's been around for years, and owners keep coming back to it: one owner has run a G2 on a 1500 and now an HD, another bought one for every truck until the current one. Among owners who've had both BAKs, most speak well of BAK covers in general; the ones who prefer the MX4 cite the tailgate routine or a G2 that had to be refunded. RealTruck doesn't describe a G2 redesign the way it does the MX4's Gen 3, but we can't confirm today's cover matches ones from a decade ago, so older reports tell you how older G2s aged, not how yours will.

• Dents: hail dents the thin aluminum skins. MX4s dent too, so this isn't a reason to pay for the MX4. UnderCover's Armor Flex has a coated top sold as dent resistant, but owners haven't reported on it in hail either way.
• Weight: a four-panel G2 is durable and secure, and heavy to fold back to the window. RealTruck doesn't publish a weight.
• The finish: a cover that sits in the sun all day can fade, and a trim dressing brings a BAK back to a deep black. RealTruck says the powder coat resists fading.
• Deck rail brackets: the drop brackets bend when you ratchet-strap a load to the relocated rails, and they're no better under the MX4. BAK's answer to one owner was stronger brackets from a hardware store. Strap heavy loads to the hooks on the bed sides instead.
• Loose hardware: the nuts that hold the front of BAK covers to the rails don't always stay tight, so check and re-tighten them now and then.

A BAK Box 2 tool box works under a G2 on a Gen14 F-150. BAK's redesigned MX4 rails no longer fit the BAK Box, so if a tool box under the cover is part of the plan, confirm it works with the exact cover you buy.

How it compares

• Versus the BAKFlip MX4: the step up. You get a tailgate that closes with the cover down, 400 lb instead of 300, 5 years instead of 3, and a matte finish. You give up money and, going by owner reports, some confidence about water: we rate the MX4's leak risk high. If you're in and out of the bed every day, the MX4's tailgate seal is worth paying for. If you open it on weekends, you'll rarely use it.
• Versus the UnderCover Ultra Flex: a hard tri-fold from RealTruck's UnderCover line at about the MX4's price on the Gen14 5 ft 7 in listing, rated 400 lb with a 5-year warranty. The listing says a dual-action tailgate seal lets the gate close with the cover up or down, and when folded it stands on prop rods clear of the cab, where the G2's stack rests against it. We rate its leak risk moderate, the same as the G2's. If you'd buy the MX4 for the tailgate, look at this one first.
• Versus the UnderCover Armor Flex: the coated-top option if dents worry you, though owners haven't reported on it in hail. Aluminum panels with a textured coating the listing sells as dent and scratch resistant, 400 lb, 5 years, EPDM seals with drain tubes, and the same tailgate-with-cover-down seal. It cost the most of these covers on most listings we compared.
• Versus a soft tri-fold like the Tyger T3: far cheaper, vinyl over an aluminum frame with a 5-year warranty. It's the least secure option here, and it's lighter and easier to live with than a heavy hard folder. If your truck has an over-the-rail bed liner, the listing says you'll cut small holes in it for the clamps. The Silverado and Sierra listings also rule out the CarbonPro bed and the factory side storage box, and warn that the cover interferes with the power tailgate.

Installing it

RealTruck's 30-minute estimate covers most trucks, with basic hand tools and no drilling. The clamps tighten with a socket and bolts, which lets a BAK cover sit tighter than one with thumbscrew clamps. Square the rails before you tighten anything. After a few weeks, re-check the clamps and the nuts at the front of the cover, since those work loose. If water shows up, reset the clamps first.

The front of the cover can take some fiddling. On a 2025 Ranger the front panel wouldn't sit flush where it meets the bulkhead seal by the cab: set on top of the seal it rode high, and slid back toward the tailgate it left a gap its owner worried would let water in. The first set of clips wouldn't engage the rails either, even after a reinstall with the rails flush. There's no published fix, so if yours sits like that, call RealTruck before you drive in the rain.

Closing up has its own order. With the cover shut, lift the rear panel, close the tailgate, then lower the panel so it latches. A Tacoma G2 that came without a tailgate gasket stays dry at the tailgate. RealTruck's G2 page doesn't describe drain tubes, so follow the install guide for your truck on drainage, and if it calls for drilling, the guide governs. On a Toyota with deck rails, plan to strap heavy loads to the bed's own tie-downs rather than the relocated rails.

Buying a used G2? They do come up for sale, but the warranty stays with the first owner. Check the bulkhead seal at the cab, the seals between the hinges and the side seals along the rails, and count the clamps; the leaking Canyon cover came with the truck, with worn side seals and a clamp missing, and replacement seals can be hard to find. Match the part to the truck as well. A 2024 Ranger G2 doesn't fit a 2026.

Who should save the money

Buy the G2 if you want BAK's fold-to-the-cab design, a locked bed and the full bed back when you need it, and you don't mind lifting a panel to shut the tailgate. Think sports gear, folding chairs and road-trip luggage kept locked in the bed, with the tailgate opened a few times a week. For that owner the extra step is a non-issue.

Step up to the MX4 if you're in the bed several times a day, want 400 lb and five years of warranty, or plan to keep the truck past year three. If dents worry you, the Armor Flex's coated top is sold as dent resistant, though owners haven't reported on it in hail. And if the money matters more than security, a soft tri-fold does the basic job for far less.
