If you shop by truck on our site, you'll often face the BAKFlip G2 vs MX4 choice for the same bed, with the MX4 priced higher. From across the parking lot they look almost identical. Both are aluminum hard-folding covers that flip toward the cab, latch automatically and lock when you lock the tailgate.
So what does the extra money actually buy? Four things: stronger panels, a better tailgate seal, a matte finish and a longer warranty. Here's what each one means in daily use, how the MX4 EZ-Lift and MX4 TS variants fit in, what the price gap looks like on real trucks, and who should skip the upgrade and just buy the G2.
Same Folding Design, Different Build: The Quick Answer
RealTruck, which owns BAK, covers the differences in its "BAKFlip MX4 Vs. G2 Folding Tonneau Cover Comparison" (updated June 11, 2025). Both covers use aluminum panels joined by EPDM rubber hinges, aluminum side rails, clamp-on installation with no drilling, auto-latching rails and a latch that's secured when you lock the tailgate. Both fold forward for full bed access.
The differences are panel cores, load rating, rear seal, finish and warranty.
Quick answer: if you open and close the tailgate every day, or you ever set weight on top of the cover, the MX4 earns its price. If the bed mostly stays closed and you want solid security and weather protection for less money, the G2 does the job.
Panels and Load Rating: Standard vs Heavy-Duty Cores
Both covers use aluminum-skinned panels over a core. According to RealTruck, the G2 uses standard-duty cores and the MX4 uses heavy-duty cores. That's where the load-rating difference comes from: 300 lb evenly distributed for the G2 and 400 lb for the MX4.
What "evenly distributed" means
It means the weight is spread across the cover. Neither rating means you can stand on one spot, drop a toolbox on the middle of a panel or park a motorcycle wheel on it. Treat the rating as a measure of how stiff the panels are, not as a cargo deck.
Does the extra 100 lb matter to you?
If you never put anything on top of the cover, the extra 100 lb won't change your day. If you set down firewood, coolers or gear bags while loading, or you work out of the truck and use the cover as a staging surface, the stiffer MX4 panels give you more margin.
Security is about the same
RealTruck describes the MX4 as having cut-resistant panels, auto-latching rails and a latch that's secured once the tailgate is locked, and rates the G2's security as nearly identical. Your bed is as secure as your tailgate lock on both.
Sealing: The G2's Overlapping Seal vs the MX4's Dual-Action Tailgate Seal
For most owners this is the difference they'll notice every day.
- G2: the overlapping rear seal sits over the tailgate, so the tailgate has to be closed before you latch the rear of the cover. If the cover is down and you drop the tailgate, you'll need to unlatch and lift the rear panel before you can shut the tailgate again.
- MX4: the dual-action tailgate seal lets you open and close the tailgate with the cover latched.
RealTruck calls the G2's routine a minor inconvenience, and it is minor if you use the bed a few times a month. If you're in and out of the tailgate at every job site, trailhead or grocery run, it gets old fast. That's the strongest real-world argument for the MX4, stronger than the load rating for most buyers.
Both covers use EPDM rubber seals along the bed rails, bulkhead and tailgate. A tonneau cover isn't a substitute for a sealed box, so keep anything that must stay dry in a dry bag or sealed container either way.
BAKFlip G2 vs MX4: Side-by-Side Comparison
Finish and looks: gloss vs matte black
The G2 has a glossy black coating on its aluminum components. The MX4 has a matte black finish. BAK markets the matte finish on newer MX4 variants as a scratch-resistant coating (the MX4 TS listing calls it Multi-Shield). If your truck has a matte or textured trim package, the MX4 will probably match better. If it's all gloss black, the G2 won't look out of place.
| Factor | BAKFlip G2 | BAKFlip MX4 |
|---|---|---|
| Panel construction | Aluminum, standard-duty cores | Aluminum, heavy-duty cores |
| Load rating (evenly distributed) | 300 lb | 400 lb |
| Rear seal | Overlapping; close tailgate before latching cover | Dual-action; tailgate opens and closes with cover latched |
| Finish | Gloss black | Matte black |
| Security | Auto-latching rails, locks with tailgate | Auto-latching rails, locks with tailgate |
| Installation | Clamp-on, no drilling | Clamp-on, no drilling |
| Warranty (BAK warranty page) | 3 years | 5 years |
| Variants we list | G2 | MX4 Matte Finish, MX4 EZ-Lift, MX4 TS |
| Price vs G2 at TRP | — | Higher; varies by truck and variant (see price check below) |
| Best for | Occasional bed use, lowest price | Daily tailgate use, weight on top, racks or assisted lift |
Warranty Differences (and How to Register)
Older BAK comparison charts and some dealer pages still list shorter warranties, which is why you'll see different numbers online. BAK's current warranty page on realtruck.com lists:
- BAKFlip MX4: 5 years
- BAKFlip G2: 3 years
Coverage is for structural defects in material and workmanship, starting from the retail purchase date. BAK states that this page supersedes previous warranty statements in its catalogs and marketing materials. Two conditions matter:
- Warranty registration must be on file and/or you need a detailed, dated receipt. Register the cover when you install it and keep your order confirmation.
- The warranty is nontransferable, so it only covers the original purchaser. If you sell the truck with the cover, the new owner isn't covered.
For a claim, BAK asks for your order number, contact details, vehicle year, make and model, product name or part number, a description of the issue, the original receipt and photos.
MX4 Variants: Matte, EZ-Lift and TS Rails
Our hard-folding tonneau cover category lists three MX4 versions, and they aren't interchangeable choices. Pick the one that matches how you use the bed.
MX4 Matte Finish
The core MX4 described above: heavy-duty panels, dual-action tailgate seal, matte finish and a 400 lb rating.
MX4 EZ-Lift
RealTruck says EZ-Lift makes the cover about one-third the effort to lift, with a large paddle handle that unlatches automatically as you lift. It keeps the 400 lb rating and the 5-year warranty. It's a good pick if a shorter driver or a tall truck makes folding a standard cover awkward, or if you open the cover one-handed with your arms full. Some fitments have extra requirements (one RealTruck EZ-Lift listing requires the factory deck rail system), so read the product notes for your truck.
MX4 TS
The TS adds integrated T-slot side rails so you can mount crossbars, racks, cargo carriers or a tent over the bed. The rack and accessories are sold separately. If you're building toward an overland setup (see How to Upgrade Your Truck for Weekend Trails Without Going Full Lift), this is the MX4 to buy. That answers "MX4 vs MX4 TS": buy the TS only if a rack is in your plans, because the T-slot rails are built into the cover.
Where F1 and FiberMax fit
BAK also makes the BAKFlip F1 and FiberMax. BAK's warranty page lists the F1 at 5 years and the FiberMax at 3 years. We'll compare those in a separate MX4 vs F1 vs FiberMax guide. For the G2 vs MX4 decision, they're a different branch of the lineup.
Price Gap, Fitment and Which One to Buy
Price gap by truck
Prices depend on truck and bed length. Here's what our hard-fold listings showed on September 25, 2026 (PT). Check the live price for your truck before you decide.
| Truck and bed | Cover | TRP price (Sept. 25, 2026) |
|---|---|---|
| 2005–2015 Toyota Tacoma, 5 ft | G2 | $1,099.99 |
| 2004–2014 Ford F-150, 5 ft 6 in | G2 | $1,099.99 |
| 2004–2014 Ford F-150, 5 ft 6 in | MX4 EZ-Lift | $1,349.99 |
| 2004–2014 Chevy Silverado 1500, 5 ft 8 in | MX4 Matte Finish | $1,199.99 |
On that F-150, the step from G2 to MX4 EZ-Lift was $250. The gap on other trucks and variants will differ, so compare the G2 and MX4 listings for your exact truck and bed length.
Choose the G2 if:
- You rarely use the tailgate while the cover is closed
- You don't put weight on top of the cover
- You want BAK's latch-with-the-tailgate security at the lowest price
- Gloss black matches your truck
- A 3-year warranty is enough for how long you'll keep the truck
Choose the MX4 if:
- You use the tailgate daily
- You set cargo on the cover while loading (400 lb vs 300 lb rating)
- You want the 5-year warranty
- You want EZ-Lift's assisted opening
- You plan to run a bed rack or tent (MX4 TS)
Fitment: find your truck and bed length
BAKFlip covers are made for specific trucks, not universal. Before you order, confirm:
- Year, make and model, including body style (for example, "Classic" vs new-body Ram 1500)
- Exact bed length. Measure it if you aren't sure.
- Bed accessories such as factory track or deck rail systems, Ram Box storage or bed-mounted boxes. Some listings are specific to these, and some bed storage systems aren't compatible.
Every cover in our catalog names the truck and bed length in the title. Confirm fitment for your vehicle on the product page, and text us if anything is unclear. If your truck also tows, the cover isn't the only upgrade worth doing. See Best PowerStop Kit for Trucks That Tow, and Silverado owners can check Best Shocks for Silverado 1500.
Common Questions
Is the BAKFlip MX4 worth it over the G2?
It's worth it if you use the tailgate often or put weight on the cover. The MX4's dual-action tailgate seal lets you open and close the tailgate with the cover latched, while the G2 requires the tailgate to be closed before you latch the cover. The MX4 is also rated for 400 lb evenly distributed (vs 300 lb), has heavy-duty panel cores and a matte finish, and BAK's warranty page lists 5 years vs 3. If none of that matters to you, the G2 is the better value.
Can I open the tailgate with the BAKFlip G2 closed?
You can open it, but you'll need to unlatch and lift the rear panel before you close the tailgate again. The G2's overlapping rear seal sits on top of the tailgate, so RealTruck says the tailgate must be closed before you latch the cover. The MX4's dual-action seal removes that step.
What's the warranty on the BAKFlip G2 and MX4?
BAK's current warranty page on realtruck.com lists 5 years for the MX4 and 3 years for the G2, starting from the retail purchase date. It covers structural defects in material and workmanship, requires registration on file and/or a detailed, dated receipt, and is nontransferable. BAK says this statement supersedes older catalog warranty statements, which explains the shorter terms you may see on older comparison charts.
What's the difference between the MX4 and the MX4 TS?
The MX4 TS adds integrated T-slot side rails so you can mount crossbars, racks, cargo carriers or a bed tent (rack and accessories sold separately). It keeps the MX4's 400 lb rating, dual-action tailgate seal and 5-year warranty. If a rack is anywhere in your build plans, buy the TS from the start.
How is the BAKFlip F1 different from the MX4?
The F1 is a separate BAKFlip model, and BAK's warranty page lists it at 5 years, the same as the MX4. We're covering MX4 vs F1 vs FiberMax in a dedicated comparison. For most buyers choosing between the two aluminum BAKFlips, the G2 vs MX4 decision comes down to the tailgate seal, load rating and warranty.
Do BAKFlip covers require drilling?
No. RealTruck describes both the G2 and the MX4 as clamp-on installations with no drilling, done with basic hand tools. Some fitments, particularly trucks with factory bed rail or track systems, have specific listings or requirements, so check the product notes for your truck and bed length before ordering.
