- Weight (90 lb) is the F-150 listing's item weight; the 500 lb rating appears in the listing's details.
- Prices for the Ram and Tacoma versions were notably higher than the F-150 and Silverado when we checked.

RetraxPRO MX Retractable Tonneau Cover video review
Video by The Arkansas Gun Guy on YouTube. Independent creator content, shown as a reference. It is not part of our scoring.
The RetraxPRO MX is a manual retractable tonneau cover: powder-coated aluminum slats that slide into a canister behind the cab and lock with a key. Amazon listed the 2021–2026 Ford F-150 5’7” version (part 80378) at about $1,917 on November 12, 2026, with other trucks running up to about $2,400. We haven’t tested it ourselves; this review pulls together Retrax’s specs, retailer data and owner reports. Not sure which bed you have? Start with the bed size finder, and see where it ranks in our best tonneau covers of 2026.
Who it’s for (and who should skip it)
It’s for owners who open the bed many times a day and want it locked every time they walk away: contractors, people who leave tools in the bed, anyone tired of folding and strapping panels. Slide it open with one hand, stop it where you need it, turn the key.
Skip it if every inch of bed counts or the budget is under $1,500. The canister costs about a foot of bed, and the Gator EFX gives you a lockable hard cover for about $549. If you want hard-cover security with nothing on the bed floor, look at the BAK Revolver X4s.
Security and locking
This is the cover’s main strength. Unlike soft covers and most hard folders, which are only secured by your tailgate lock, the PRO MX has its own key lock. Retrax says it holds the cover at any point along the rails, so a ladder or a tall load can stick out of a half-open bed with the rest still locked. The slats are 1 in thick aluminum, rated for 500 lb evenly distributed (maker claim). On our three security levels it’s a level 3; our most secure tonneau covers guide explains the scale.
One caution on the “any position” claim: Car and Driver tested a different retractable, the GatorTrax, and its tester could lock it only fully closed or fully open. That isn’t a test of the Retrax, but it’s a reason to check the behavior on your own truck.
Bed access and everyday use
The trade-off is the canister. etrailer lists it at 13-1/2 in deep by 12 in tall (a staff answer gives slightly different figures), and its experts say it takes roughly the first foot of the bed. On a 67.1 in F-150 short box that leaves about 53.6 in fully open, about 80% of the bed. On 6.5 ft and 8 ft beds the canister costs a smaller share. Run your own truck in the bed access calculator.
Day to day there’s nothing to fold, strap or remove, and the low-profile rails sit about 1 in above the bed rails.
Weather sealing and drain tubes
Retrax uses foam seals along the rails, weather stripping and built-in drain tubes. Those tubes matter: water that runs off the slats collects in the canister, and the tubes route it out through the bed’s drain holes. One etrailer owner review says the cover isn’t watertight in heavy rain or a car wash. Car and Driver’s water test of the GatorTrax retractable found leaks at the cab-side corners and from the canister until a drain was fitted, and it concluded that no cover it tested was fully waterproof. More in are tonneau covers waterproof?
Install and fitment
The listing describes a clamp-on design you can fit alone or with a friend using basic tools. Plan time for the drain tubes: if your truck has a spray-in liner over the drain holes, you may need to open them up.
We checked these listings: F-150 2021–2026 5’7” and 6’7”, Ram 1500 2019–2026 5’7” (not the Multi-Function tailgate), Silverado/Sierra 1500 2019–2026 5’10” (works with MultiPro/Flex tailgates, not the CarbonPro bed), Tacoma 2016–2023 Double Cab 5’1”, Tundra 2022–2025 5’7” with the deck rail system, and Colorado/Canyon 2023–2025. The Ram and Tacoma versions cost about $2,300, noticeably more than the F-150 and Silverado. Confirm the part number with the listing’s fitment tool.
What you’ll need beyond the box
- A rack plan, if you want one. Retrax sells T-slot versions and XR rails; the Thule Xsporter Pro Shift lists retractable covers as compatible. Retailer Q&A says the Yakima OverHaul HD doesn’t fit. See covers with a bed rack.
- A bed mat such as the Husky Liners mat for the F-150 5’7” bed, so cargo doesn’t slide into the canister.
- Cargo control: a ratcheting cargo bar keeps loads back from the canister.
More on the accessories page.
Reliability and warranty
Retrax backs the PRO MX with what it calls a Legendary Lifetime Guarantee, a limited lifetime warranty and by far the longest of the retractables we track. The F-150 listing showed 22 ratings averaging 4.8, and the Ram listing 168 ratings at 4.4.
Bottom line
The RetraxPRO MX is the low-effort, high-security cover: aluminum slats, a key lock and a lifetime warranty, with nothing to fold. You pay for it twice, once at about $1,900 or more and again with a foot of bed. If that’s acceptable, it’s our top retractable; compare it with the smaller-canister option in RetraxPRO MX vs Roll-N-Lock M-Series, or check the price.
Accessories that pair with the RetraxPRO MX
Cover care, bed racks, mats and cargo gear sold on Amazon. Most bed and floor products are vehicle-specific: the fitment shown is the listing we checked, so search the same product for your truck if yours differs.
- Bed rackThule Xsporter Pro Shift truck rack (500010)Compatible, third-party
Sliding 18 in towers that move along the bed for different loads, rated to 600 lb per the listing. A rack that rides on its own rails is the usual way to combine bars with a retractable cover. Requires Thule TracRac base rails (sold separately). The listing says it's compatible with retractable tonneau covers 'see fit guide', so confirm your exact cover in Thule's fit guide.
- Bed rackThule TracRac SR base rail (217870)Compatible, third-party
The drill-free base rails the Xsporter Pro Shift and TracRac SR racks mount to. Needed for the Xsporter Pro Shift; check Thule's fit guide for your truck and cover before ordering.
- Bed rackYakima OverHaul HD adjustable truck bed rack (8001151)Works with any cover
Height-adjustable towers with T-slots and SKS locks, rated 500 lb on-road and 300 lb off-road per the listing, for rooftop tents, ladders and boats. The Amazon listing doesn't state tonneau-cover compatibility. Check Yakima's fit guide for your truck and cover before buying.
- Cargo managementKeeper ratcheting cargo bar, 40–70 in (05059)Works with any cover
Pins groceries and gear against the bulkhead or tailgate so nothing slides around under a closed cover. It sits below rail height, so the cover closes over it. 40–70 in span; measure between your bed walls at the height you'll use it.
- Cargo managementRhino USA ratchet straps, 1 in × 15 ft (4-pack)Works with any cover
Tie-downs for loads strapped to a bed rack, or tall cargo you haul with a roll-up or folding cover open.
- Cargo managementMigaven heavy-duty truck bed cargo net, 4 × 6 ftWorks with any cover
The fallback when a load sticks up past the rails and the cover has to stay open: a stretch net over the bed keeps loose items in.
- Cargo managementRough Country slide-out truck bed cargo tray (10209)Works with any cover
Brings small items to the tailgate so you don't have to crawl under a cover to reach the front of the bed. Rough Country says the 4 in tray fits under any bed cover. Listing fitment: Trucks with a 5'7" or longer bed (tray is 62.3 × 23.6 × 4 in). Per the listing, fits beds 5'7" or longer; 5 ft midsize beds are too short.
- Cargo managementDECKED drawer system (XR7)Works with any cover
Two bed-length lockable drawers under a flat deck rated for 2,000 lb of cargo per the listing. Under a locking cover, it turns the bed into secure tool storage. Listing fitment: 2019–current Ram 1500 (DT) 6'4" bed, not RamBox. A drawer system raises the bed floor, which cuts the height left under a cover. DECKED sells a separate model for each truck and bed length.
- Bed matHusky Liners custom-fit rubberized bed mat (16008)Works with any cover
A rubberized mat with air-dry nibs underneath, so water that gets past a soft cover's seals can drain instead of sitting on the paint. Listing fitment: 2015–2026 Ford F-150 and 2022–2026 F-150 Lightning, 5'7" bed. Per the listing, it will not fit over a drop-in bed liner.
- Bed matRough Country heavy-duty rubber bed mat (RCM671)Works with any cover
A cheaper rubber mat that protects the floor and keeps cargo from sliding into the tailgate. Listing fitment: 2015–2027 Ford F-150, Lightning and Raptor, 5'7" (67 in) bed.
