Features to know about

Secure Cargo in All Conditions: Heavy-Duty Aluminum Construction

The RetraxPRO XR uses 1" thick aluminum slats that can handle up to 500 lbs of evenly distributed weight. Its matte black finish is scratch resistant and won’t fade, keeping the cover looking sharp through years of use. Weather stripping and foam seals block out rain, snow, and dust, while the cover overlaps the tailgate for an extra-tight seal. Even the locking handle is shielded against dirt and water, so the mechanism stays smooth and corrosion-free.

Full Bed Access Anytime: Retractable Design with Sealed Ball-Bearing Rollers

When you need to load big gear or tools, the cover slides open in seconds. It glides smoothly on sealed ball-bearing rollers—no springs, straps, or snaps to fight with and no lubrication required. The cover can latch at any point along the rails, letting you keep smaller cargo covered while leaving room for longer loads. When fully retracted, it rolls into a compact canister with a spiral track system that keeps the panels from rubbing together for long-term durability.

Haul More Above the Bed: Built-In T-Slot Rails for Racks

The integrated Trax Rail System along the side rails lets you mount T-slot-compatible racks from brands like Yakima, Thule, and Rhino-Rack (sold separately). You can carry bikes, kayaks, or ladders above the bed while keeping the cover closed and your gear below protected. The cover and rack system work together without interfering with each other, so you can haul more without compromise.

Sleek Look and Easy Setup: Low-Profile, Clamp-On Design

The side rails sit just 1" above the bed for a clean, low-profile finish that blends into the truck’s lines. The canister has an angled bottom that leaves more usable space underneath, and when closed, the cover sits nearly flush for a smooth, finished look. Installation is straightforward—just clamp the rails on, secure the canister, and attach the included drain tubes. No drilling or special tools needed.

Long-Term Reliability: Maintenance-Free Operation

With no joints, hinges, or exposed springs, the RetraxPRO XR is built to keep working smoothly without maintenance. The sealed ball-bearing rollers and corrosion-resistant materials mean you won’t be dealing with seizing locks or stuck panels. You get consistent, smooth operation every time—whether it’s the middle of summer or a snowy morning.

I have these tops on both of my trucks. Very durable and the powder coating is still in excellent condition.



by:

It is great. Took about 2 hours to install. You will need 2 people to put the assembled cover in the bed. I do have the multiplex tailgate and rain water will get into the bed because of the gap in the tailgate sections.



by:

Love the look and feel of the cover.



by:

Need I say more... :)



by:

Tonneau cover was delivered to my door with no damage. Hope to install it this weekend, weather permitting.



by:

It doesn’t lock into any position very well, either have all the way open or close. At time after I unlock it then I have to open the tail gate pull it to get it to unlock.



by:

Showed up quickly, this is the 3rd purchase from etrailer.com, they have great customer service, they know their products, prices are reasonable and they ship fast. I also purchased the Curt Hitch from them.



by:

Order was processed quickly and arrive in the specified shipping time. Easy two person install and fine tuning is an easy one person job. Great quality top and rugged. Perfect top for your pickup. Bed stays water tight so storing sleeping bags or luggage is no problem on long trips.



by:

Easy install nice and clean.



by:

Short version, LOVE IT!!! This was a lot more money than I wanted to spend but it was well worth it. While not water tight it is close. Easy to install, easy to operate. Does not make noise even on washboard roads. The loss of space by having a canister has not impacted me. But I saved the best for last. My daughter wanted one for her truck so I ordered another one. It was damaged in shipment and the best customer service representative in the world, Kimberly O, helped me out by getting me a new replacement quickly. I highly recommend this Tonneau Cover. I also got T-Slots and use my Rhino crossbars with the cover. No problems, just like they were made for each other.



by:

I had a solid tonneau before and liked it. Only problems with it were you could not drive with the cover up and it was a bear to remove even with the help of my wife. That truck was totaled by a drunk driver. So the replacement truck had to have an easier cover and wile I was at it, why not some racks as well?
It looks great! Fits perfectly and was a synch to install.
On the down side it is not completely dry and it did freeze up once in the winter. Other than that I do like it and gave it 4 stars



by:

Thanks etrailer. Ordered the Yakima Overhaul ladder racks and the Retrax tonneau cover. It’s the perfect solution for our camping/kayaking trips. Both products are solid and top notch. Installation was a breeze on my 20 Tundra.



by:

Nice product. Had shipping damage etrailer made it right.



by:

Really like this cover. Installation was fairly straightforward I was able to do the install myself but another person would have been helpful.

Retrax Pro XR with Rhino Rack Cross Bar set for the XR

This has greatly simplified my bicycle transport. Before I was using separate ladder rack on back of trailer, and hitch rack on truck. Compared with my prior setup, here are the improvements:
-- removes ~75 lbs from back of my trailer
-- not dealing with separate truck and camper bike racks (esp hitch rack taking up bed room while towing)
-- don't have to unload bikes to check something on camper roof
-- bikes are easier to load (even with lifting)
-- cross bars detach in seconds and lift off for full bed access or car wash (the cross bar and bike rack assembly stores on hook in garage)
-- Don't have to remove and store bike seats (they extended well past right side of trailer when on ladder rack)
-- Bikes are more protected above tonneau cover than either on hitch rack or ladder rack.



by:

The Retrax Pro XR cover performs and looks like new after 1 year. Took 2 of us to install and adjust properly. Very minimal water leakage around tailgate sometimes which is expected. Read reviews of water leaks but must be due to improper installation/adjustment. Very satisfied and looks great. 2024 GMC 2500HD Denali



by:

The Retrax Pro HR and Yakima Overhaul HD is a perfect combo and works well together.



by:

We really like the bed cover. Wish it was more waterproof but still really nice.



by:

Great fit. I had on on my old F150 and like the fit even more on my new Ram 2500.



by:

I couldn’t be happier with this tonneau cover for my F450. It shipped well, arrived quickly, and was packaged securely with no damage at all. Everything was organized and protected right out of the box.

Installation was surprisingly easy — clear instructions and no headaches. I had it mounted in no time, and it fit my F450 perfectly. The alignment was spot-on and the clamps secured tightly without any modifications needed.

The cover looks great, feels durable, and gives the truck a clean, finished appearance while keeping the bed fully protected. It opens and closes smoothly and feels solid once locked down.

If you’re looking for a tonneau cover for your F450, this is a great choice. Fast shipping, easy install, and excellent quality — 5 stars all the way!



by:

Quality and fit and finish seem strong. Straightforward install.
Would be 5 stars if the cover could close while using the Toyota tie-down system. The locking components knock up against the OEM tie-down brackets and stop the tonneau cover from closing.
Secondly, the OEM Toyota tie-down brackets cannot be used in the accessory T-slots as the OEM brackets have a larger T and cannot slide into the RetraxPRO accessory T-slots.

So,. I've paid for two different tie down systems , Toyota and Retrax and still don't have a solution. At my age I should have known better and done more research.



by:

Replaced my "soft" tonneau cover that was tearing, fading, and falling apart after 10 years of faithful service. Bought this tonneau cover because of the retractable operation and the aluminum construction. While it is obviously built tougher and the operation is smooth, it does have its downfalls (which I didn't think of too much at the time). One being the space that is lost in the front where all that retraction goes, I guess there is around 8 inches of height at the very front. Additionally, where it lays is slightly lower than the bed rails which takes away at least around an inch of height compared to my previous cover. This makes a big difference when getting tall containers and the like to fit. I do enjoy the elevated level of security the new tonneau cover offers, even though I had zero problems with the previous cover.



by:

Easy to order and find the correct fit. This is my third cover from this brand and my first with aluminum slats instead of polycarbonate due to a different truck size. Installation took about two hours from start to cleanup, and I needed a couple of neighbors to help lift it since the aluminum version is heavier. My previous polycarbonate covers didn’t leak and worked well, but they became slightly wavy over time. I expect the aluminum version to hold up better.

Installation note for 2026 Ram 3500 Dually: when positioning the clamps at each set of plastic allen screws had to adjust front and back clamps The front clamp near the cab bolts were a bit short due to the wider gap between bed and tonneau rail, so I removed the top back piece of the clamp to secure it properly. The lower supports did not fully reach the side walls, and the rear clamp near the tailgate required removing the lower support bolt to clear the cargo light. The middle clamps fit as intended with no adjustments. Something for the manufacture to consider as new trucks come out with different accessories.

Overall, I’ve been very happy with this brand over the years and am satisfied with this purchase.



by:

Was relatively simple to install and works as advertised. Not my first of these covers so I am a return customer and also new what to expect with installation. The PDF instructions are good, but not quite Lego or IKEA level. I haven't installed the Yakima HD Overhaul System yet, but do not expect any issues.



by:

I installed the RetraxPro XR tonneau cover myself and it wasn't bad at all. I had to do a lot of adjusting to get it perfectly straight and even. The hardest part was having my wife help me lift the cover in the truck after it was assembled. I wish they would include some kind of a reducer to be able to fit the drain hoses into the smaller holes in the bed of the truck so no drilling would have to be made. Other than that, great bed cover and can't wait to add T-slot accessories.

  • Bed Clearance for Cargo with RetraxPRO XR Tonneau Cover Installed on 2018 Ford F-150
    The rails for the RetraxPRO XR sit on top of your 2018 Ford F-150 bed rails so you will have clearance from the bottom of your truck bed to the top of your bed rails. There are parts that hang down a little further like the clamps, but overall you will have that standard clearance. The canister that the tonneau cover stores inside measures 13-1/2" deep x 12" tall so you will lose that much space at the cab-end of your bed. The correct tonneau cover depends on what size bed you have: 5-1/2'...

  • 2018 Ford F-150 Ladder Rack and Tonneau Cover Recommendation
    The Thule Xsporter Pro Truck Bed Ladder Rack # TH500XTB isn't compatible with a tonneau cover because it uses a clamping system that sit in the same space as the tonneau cover rails so you won't be able to install both at the same time. We do have some options for adding a tonneau cover and ladder rack on your 2018 Ford F-150 though so this setup isn't completely out of the question. My favorite combination is a Retrax cover that comes with the XR rails which makes it compatible with the...
