Best Tonneau Cover for a Tacoma: Picks for 3rd and 4th Gen

A Tacoma's short bed is about 5 ft on both the 3rd gen and the 4th gen, and that changes the math on a cover. A canister that eats a foot of floor or a folded stack parked in the rear window costs you more here than on a full-size truck.

For most Tacomas the answer is the UnderCover Ultra Flex. It isn't the cheapest cover here or the driest, but it does the most well on both generations: it seals better than the BAKFlip MX4, stands its folded panels off the glass and carries a 5-year warranty. The other four picks each win one job: a clear rear window, rack rails or a much lower price.

Two things matter more than the brand. One is your generation, bed and rails. Every cover here is a separate part for the 3rd gen (2016-2023) and the 4th gen (2024 on), and every 4th gen listing we confirmed for our picks calls for Toyota's factory rails. The other is what else the bed has to do: carry a rack, swallow a dirt bike or keep tools locked up at a job site.

The best Tacoma tonneau cover for each job

Start with the job, then pick the cover.

• Best overall: the Ultra Flex. Its water record beats the MX4's, the folded stack stands on two prop rods off the cab, and RealTruck rates it at 400 lb evenly distributed with a 5-year warranty. It has no keyed lock; it opens only with the tailgate down, so your tailgate is the lock.
• A clear rear window: the BAK Revolver X4s. Aluminum slats under a one-piece vinyl top roll to the cab with one hand and strap there. It costs more than the Ultra Flex on every Tacoma listing we compared, and it rewards a patient install: front corners that won't lie flat are the usual complaint.
• A rack on the cover (3rd gen): the RetraxPRO XR. T-slot rails run the full length, and its keyed latch locks at any point along the track. It's the most expensive cover here, and its canister takes about a foot off the front of the bed for good. 4th gen owners, see the rack section.
• Budget roll-up: the TruXedo Lo Pro. Soft vinyl that rolls to the cab for nearly the whole bed, with a limited lifetime warranty. No lock, no load rating, and expect some water at the corners in a car wash.
• Cheapest: the Tyger T3 Soft Tri-Fold. Vinyl over an aluminum frame and a 5-year warranty for far less than the name brands. No lock, no load rating, and the folded stack sits on about the front third of the bed.
• Security: only the RetraxPRO XR has a keyed lock. The Ultra Flex opens only with the tailgate down and the X4s's release cables sit at the tailgate end, so on both, a locked tailgate keeps the bed shut. If tools ride in the bed overnight, buy a hard cover and lock the tailgate.

The five covers side by side

Here are the picks from their makers' pages and listings, with what each means on a Tacoma:

All five clamp on without drilling into the bed on most trucks, per their makers, and none has a published cover weight. Drain tubes are the exception to plan for: the RetraxPRO XR's canister tubes have to be routed out of the bed, and a 4th gen Tacoma's drain holes are small, which the drain section below covers.

Read the ratings for what they are. Evenly distributed means weight spread across the whole closed cover. None of these numbers covers a cooler sitting on one panel or a rack on the move, and the two soft covers have no rating at all. Tyger's warranty says to put no weight on the T3, and that includes a wet load of snow, so clear it after each storm.

Folder, roll-up or retractable on a 5 ft bed

On a Tacoma we'd take a hard folder or a hard roll-up over a retractable unless you need the rails. The short bed makes every inch of lost floor hurt.

The Ultra Flex folds to the cab, where the stack takes roughly the front 8 in of the bed and stands right behind the rear window. On a 60 in short bed that leaves about 52 in of floor, and it blocks much of the view out the back while you drive with it open. The X4s rolls into a tight roll at the cab that takes about as much floor, by one owner's estimate, and leaves the glass clear. That's the trade between our top two picks: a better long-term record and a lower price against a clear window.

A retractable costs more floor. RealTruck doesn't publish the RetraxPRO XR canister's footprint; on a 4th gen Tacoma, owners measure about 13 in off the top of the bed, with about 18 in of height under it for flat gear and straps. On a 60 in bed that leaves about 47 in of full-height floor. A 3rd gen owner who likes their Retrax still won't put one on the next Tacoma for exactly that reason.

The soft covers split the same way. The Lo Pro rolls to the cab for nearly the whole bed. The T3 folds into a stack that sits on about a third of the bed, about 20 in of a 5 ft bed, which is the price of its low cost. If you haul dirt bikes, plywood or anything that needs the front of the bed, a roll-up or a cover you can pull off quickly makes life easier than any tri-fold.

3rd gen or 4th gen: bed lengths and the right listing

The 3rd gen Tacoma (2016-2023) and the 4th gen (2024 on) both come with a short bed of about 5 ft and a long bed of about 6 ft, and the listings name them differently. RealTruck's 3rd gen listings call them 5 ft 1 in (60.5 in) and 6 ft 2 in (73.7 in), while Tyger calls the 3rd gen short bed 5 ft (60 in). On the 4th gen, BAK's listings say 5 ft (60 in) and 6 ft (72 in), UnderCover's say 5 ft and 6 ft 2 in, Tyger's long bed is 6 ft (74 in), and LEER calls the beds 5 ft 2 in and 6 ft 2 in. Match the listing by generation and short or long bed, not by the number on the title.

Every cover here sells separate 3rd gen and 4th gen parts, so buy the one listed for your model year. A separate part number doesn't prove a cover won't fit the other generation, but we'd never count on it. A Lo Pro did move from a 2010 Tacoma to a 2021 and fit, and its own review still says to buy the listing for your year. Cab matters on one pick: the RetraxPRO XR's 3rd gen 5 ft 1 in listing is for the Double Cab, and its 6 ft 2 in listing names the Regular, Access and Double Cab.

Watch the years on the Ultra Flex. Both of its 4th gen listings read 2024-2025, so if you drive a 2026, confirm the fit with the seller before you order.

Deck rails, storage boxes and the tailgate

On a 4th gen, look at your bed before you shop. The listings name Toyota's rails several ways (deck rail system, OE track system, utility rail system), and every 4th gen listing we confirmed for our picks calls for them, per the listing or RealTruck's page. RealTruck says the Ultra Flex's 5 ft install requires the deck rail system, as do the X4s's and the Lo Pro's 5 ft parts, and that Toyota sells the rails if your truck lacks them. The X4s's 6 ft listing is for trucks with the OE track system, and the T3's 6 ft listing fits only trucks with the factory deck rail system. If your bed is bare, price the rails in or confirm with the seller.

The rails and their cleats change with the cover. On the RetraxPRO XR, RealTruck says the bulkhead tie-downs come out for good so the canister fits, while the cover's brackets mount in the deck rails, so you keep the rails with less room to slide the cleats. Owners say Toyota's own tri-fold moves the rails a little lower and inward with the cleats still sliding the full length of the bed, and that the current MX4 for the 4th gen leaves the rails where they are, so ask before you buy if an accessory needs the rails in their factory spot.

On a 3rd gen with factory bed storage boxes, read the fine print, because the sources disagree. The Lo Pro's short-bed listing excludes the Trail Special Edition storage boxes while RealTruck's page for the same part says it works with them. The Ultra Flex's short-bed listing says it fits with or without the bedside storage boxes, and RealTruck's page for that part says it won't work with factory bed storage boxes. RealTruck also says the X4s's 5 ft 1 in part won't work with them, and the T3 listing excludes trucks with the Trail Special Edition boxes. Ask the seller before you buy.

The 3rd gen has two rail quirks of its own. The factory rails on some 2016 and 2017 trucks dip enough to cause side-rail leaks, and some roll-up rails ride up where the bed flares in at the tailgate. Look along the rail at the tailgate end before you tighten anything.

The tailgate is your lock on most of these covers. The Ultra Flex lets the tailgate open and close with the cover shut, per its listings, and the cover itself opens only with the tailgate down. The X4s's release cables sit at the tailgate end. The Lo Pro and the T3 have no lock. If your tailgate doesn't lock from the factory, budget for a tailgate lock.

Keeping a Tacoma bed dry, drain holes included

No cover here keeps a bed bone dry through every car wash. Of the five, the X4s and the Ultra Flex rate driest. The X4s stays on the dry side and has no drain tubes to route, though its record is short. The Ultra Flex keeps the bed dry about as often as not, and when water gets in it's usually a little in one spot or one kind of weather, a clearly better record than the MX4's. The RetraxPRO XR lets at least a little in on most trucks, along the side rails first, and the soft covers depend on tight vinyl. The driest cover we've reviewed, the TruXedo Sentry CT, is covered below; it's the only one with a low reading on our leak-risk gauge.

On a 4th gen, plan the drain tubes before the first storm. The bed's drain hole is 5/16 in, and the MX4's tube is 5/8 in, so owners either drill or fit a barbed reducer. Not every cover forces the issue: on a 4th gen with a spray-in liner, the tubes on Toyota's own tri-fold went through the stock holes once they were cut at an angle. On another, the same cover's tubes blocked two-thirds of the existing holes, and a nose-down rake pooled water in the front corners. If you add a drain hole, find out what sits behind that corner of the bed first, and let your cover's install guide decide where it goes.

Snow and ice need a plan too. RealTruck's warranty on the Ultra Flex asks you to clear snow and ice before you open it. Owners split on the X4s in winter: one ripped theirs off after it froze shut, while another has run one through three Nova Scotia winters by brushing the snow off and knocking loose ice with a fist. Clear heavy snow before you roll or fold any cover.

Seat the bulkhead seal carefully, hose-test the cover before you load anything that matters, and check it again after the first car wash. With a drop-in liner, the X4s uses its thinner bulkhead seal and some drop-ins need trimming at the corners. If cargo has to stay bone dry, look at a cap; we haven't reviewed one yet.

Racks on a Tacoma cover

If the rack mounts on the cover and you drive a 3rd gen, buy the RetraxPRO XR. Its T-slot rails run the full length of the cover, and Leitner's TONNEAU rack rides on those rails, with Tacoma parts for the short bed (Double Cab) and the long bed that cover the 3rd gen. Leitner says the short-bed TONNEAU won't fit trucks with the Trail Special Edition bed storage boxes. Our Leitner ACS FORGED review covers all three versions of that rack.

Read the ratings before you load anything. RealTruck rates the PRO XR at 500 lb evenly distributed on the closed cover and publishes no rack, T-slot or on-road limit, so that number isn't a rack rating. Leitner's FAQ and install guide rate the TONNEAU at 400 lb on the road and 800 lb parked, and Leitner publishes no off-road figure because the rack is secured through the cover. A 3rd gen Tacoma running a Yakima Outpost and a Tepui tent on these rails already sits at the off-road limit of the Yakima tonneau kit and the Retrax rails. Get the limit for your load from the rack maker and RealTruck in writing, and torque the rack hardware to the figures they give you, not by feel; overtightened bolts have bent the PRO XR's aluminum tracks.

On a 4th gen, we haven't confirmed a T-slot cover on an Amazon Tacoma listing yet. RealTruck lists 4th gen RetraxPRO XR parts for the 5 ft bed with the deck rail system and the 6 ft 2 in bed, and the PRO XR pick below links a search for them. BAK sells T-slot versions of its covers too, the MX4 TS and the Revolver X4ts, which adds T-slot rails to the X4s; check fit for your truck. Racks don't always bolt straight on: a Kuat Ibex on a 4th gen Tacoma needed modified T-slot nuts for the 6 ft bed, which may void the rack's warranty.

The other picks aren't rack bases. RealTruck's Ultra Flex pages say nothing about racks, the X4s's install sheet says not to tie cargo to the cover or its framework, and neither soft cover has a load rating to set a rack on. Leitner's in-bed FORGED and NDNS racks go under a cover only by converting to the TONNEAU, which brings you back to the PRO XR.

Other covers we reviewed for the Tacoma

• TruXedo Sentry CT: the driest cover we've reviewed, and the only one with a low leak-risk reading. It has 3rd gen 5 ft 1 in and 6 ft 2 in listings that exclude the Trail Special Edition storage boxes, and it costs less than the X4s on the 5 ft 1 in bed. The catch is the rail: on a 2019 Tacoma it sat raised at the tailgate where the bed flares in, so budget time to sort that out. RealTruck lists 4th gen versions that need the deck rail system, but we haven't confirmed one on Amazon.
• LEER HF650M: the hard folder we'd pick for security, with a latch that can't be fished open with a coat hanger and a 450 lb evenly distributed rating. It has 4th gen listings for both beds and a 3rd gen 6 ft 2 in listing for trucks with the track system, but no confirmed 3rd gen short bed. It costs less than the Ultra Flex on every Tacoma listing we compared; the trade is a 3-year warranty, and LEER no longer sells it on its own website.
• BAKFlip MX4: the folder most Tacoma owners shop, with a flush look and a tailgate that works with the cover shut. Too many arrive leaking for us to pick it; we rate its leak risk high. It has a 4th gen 5 ft listing and a 3rd gen 5 ft 1 in listing for trucks with the factory track system, and the Ultra Flex costs less on both.
• Rough Country Low Profile: a budget hard tri-fold confirmed only for the 3rd gen 5 ft bed. Its front panel stays put, which costs about 20 in of the 60.5 in bed if the three panels split evenly, Rough Country says no to bed racks, and Tacoma owners have had the most trouble getting it to sit flush. The 4th gen Rough Country listings we found on Amazon are its Flip Up, a different cover.
• Gator EFX: the budget hard folder we'd buy, with listings for the 3rd gen 5 ft 1 in and 6 ft 2 in beds. The long-bed listing won't work with Trail Edition models, and RealTruck says the short-bed part won't work with factory bed storage boxes. Expect damp corners after hard rain and a 2-year warranty.
• RetraxONE XR: the same T-slot rails as the PRO XR on a one-piece polycarbonate cover, noticeably cheaper, with 3rd gen listings for both beds. RealTruck rates it at 200 lb evenly distributed and warranties it for one year.
• UnderCover Armor Flex: the Ultra Flex with a textured coated top, for more money on both the 4th gen 5 ft and 3rd gen 6 ft 2 in listings. Pick it only if you want that finish.

Two other covers come up constantly on the Tacoma forums. Toyota's dealer hard tri-fold, which we haven't reviewed, is the one many owners start with, and owners say BAK builds the current one; reports on Toyota's covers run from a little water at the tailgate to cracked seals and faded panels on a 3rd gen inside three years. The Access LOMAX hard tri-fold has a loyal following for coming off without tools in about a minute, and it's the removable hard tri-fold we'd buy. We confirmed Amazon listings for the 6 ft bed on the 4th gen and on the 3rd gen, the latter for trucks with the deck rails and without the OEM hard cover. On a 5 ft bed, search for the LOMAX and check fit for your truck.

If you want the Sentry CT on a 4th gen, search for the 2024-on Tacoma Sentry CT and check fit for your truck.

Which cover goes on your Tacoma

Most Tacomas should wear the Ultra Flex. It seals better than the folder most owners default to, keeps its stack off the glass, and has listings for every Tacoma bed we cover. Spend more on the X4s if a clear rear window matters more to you than the Ultra Flex's longer record, and on the RetraxPRO XR only if a rack is going on a 3rd gen's cover.

On a budget, the Lo Pro is the soft cover for owners who use the whole bed, and the T3 is the cheapest cover we'd put on a Tacoma. Neither locks. If your cargo can't take a drop of water, skip tonneau covers and price a cap.
