When your hands are full or you just want quick access to your bed, the PowertraxPRO MX opens and closes with the press of a button. The wireless key fob controls the motorized retraction so you don’t have to deal with straps or snaps. It glides smoothly on sealed ball-bearing rollers that don’t need lubrication, and you can stop it anywhere along the rails thanks to an electromagnetic brake. That means you can haul long gear that sticks out of the bed while keeping the rest covered and secure.
Weather and theft can take a toll on a truck bed, but this cover is built to handle both. The 1" thick aluminum slats are impact and weather resistant, and the matte black finish won’t fade or scratch easily. When closed and paired with a locked tailgate, it’s nearly impossible to pry open or cut through. Foam seals and weather stripping surround all sides, while the cover overlaps the top of the tailgate to keep out dust, snow, and rain. Even in a heavy storm, your gear stays protected.
Loading up after dark is easier with the integrated LED light mounted on the canister. Just tap the light-symbol button on the key fob to illuminate the bed. A built-in timer shuts it off after 3-5 minutes, so you don’t drain the battery if you forget. It’s a simple feature that makes finding gear at night much easier, without exposing what’s in your bed to everyone around.
The PowertraxPRO MX is built from heavy-duty aluminum panels that support up to 500 lbs of evenly distributed weight. The canister’s spiral track system keeps the cover from rubbing against itself, and drain tubes route water safely out through the bed floor to prevent mildew buildup. The low-profile rails sit just 1" above the bed for a clean, streamlined look that holds up through years of use.
Installation is straightforward. The side rails clamp onto your bed rails and connect to the powered canister, and the included wiring harness runs directly to your vehicle’s battery. Once connected, the cover retracts smoothly and locks securely in place wherever you want it. It’s a solid, self-contained setup that gives you powered convenience and serious protection all in one.

What's up everybody It's AJ with etrailer.com. Today, we're going to be checking out the Retrax PowerMax hard tunnel cover. And now this is gonna be an automatic tunnel cover. Let me open up the back and show you. So we're gonna remote control so you can open it. With just the push of a button.
There's no straps to grab or you don't have to pull it back or push it back or anything. You can close it with that same remote and it stops anywhere you need it to. So, it's very easy to use, whether you need to open it or close it. It goes onto your Ram box. Let's take a look at it.
Because of the Ram box this one comes with hardware to specifically mount it to the track here. That lifts it up and puts it on top of the rails. That way you can still have access to the Ram boxes on the side. So that the rails are mounted up here on top. The cover's gonna be made out of a matte black aluminum.
So, it's pretty sturdy. So it can hold up. It's definitely better than some of the soft tunnel covers. Those usually have three bars in the middle and can be a problem if it rains or snow collects or even setting something down on there that can make that material bend down and cause issues down the line. This is gonna be a hard tunnel cover.
So you won't have that issue. And instead of being a tri-fold design where you have to fold it up in three spots. You don't have to manly lift anything here from the side of the truck. You can see, even with the Ram box here, that can be kind of hard to reach in there and do that over and over and then lean up against the glass. Well then you can't see out of the back. This one rolls up into the canister and the bed. So that means it's just low profile and it stays out the way. So as I put it away here, one I don't have to do anything with my hands cause it's got the remote. But it goes in that canister and then you have full bed access. For the most part. The canister does take up a little space down there. That's something else you gotta consider especially with loading with cargo. That it does take up a little bit of your bed there. So just remember that. But there is space at the bottom to still slide things in. So one thing we can do is prop it up on the tailgate. And one of the nice things about this cover versus some of the other ones, like I said, the tri-fold design you're kind of stuck by where that folds out. So you might not be able to pull it out halfway and leave it like that. With this one, you can go to close it, you can stop it wherever you need it to, so. Bring it all the way up to the ladder. Stop right there. So not only are we allowed to take the longer loads that stick out a little bit on our tailgate, but the rest of the bed is still covered. The grease ball bearings help the tunnel cover go along the track evenly and smoothly. The cover being all rolled up in the canister is nice, because with that track and the ball bearings in there it's always gonna come out evenly. So as it rolls out, you don't have to worry about it bunching up. Some of the manual ones that have the tracks though, you have to pull out, sometimes get jammed up here. When like a panel gets stuck somewhere or the ball bearing doesn't quite go. This one we've had no issues with it. Rolls out very smoothly every time. The O is for opening. This is gonna retract the cover. The C is to close. So that brings the cover to the back of the tailgate. And then this button here is gonna be the light function. The light that's built into the tunnel cover. So you can hit that on the remote and get some light. Whether it's in the evening of the job site or early in the morning, you can't quite see all the way up there in the back of your bed. Now you're gonna add some light to help you find that stuff. Looking beyond the light, you can see at the bottom there are drainage tubes there for the canister and that's gonna be helpful for if it rains and you've got your bed covered up or even some snow build up and you go to retract it. That water that goes into the canister will be able to drain out to the side of the vehicle. So you don't to worry about being stored in there and getting nasty. The cover can handle 500 pounds evenly distributed here on the cover. So that goes to say, if you go to throw like a cooler or something up there, it's gonna be able to handle it. It's not one of those soft covers where that would damage it. This is pretty sturdy, but you know, make sure you don't overdo it. Especially with the Ram boxes on the side. It can be harder to access things here in the middle. So if you need to set something here on the end to grab something outta the box or putting something in, you can definitely do that. Overall, I think it's a good cover for your Ram. Especially if you have the Ram boxes on the side. You already have that more narrow bed. You're gonna make it easiest possible to have it cover, but still have it function. I like that it can stop wherever you need it to. So you're not just restricted to the three quarter panels or just completely removing it. You don't have to remove it. Now it does take up a little of your bed. So that'd be one thing I'd be concerned about. Just the canister coming out to here. And then the cover's stopping here too. So it does eat up a little of your bed, but overall you can still fit things underneath or prop it up and still get the cover for most of it. So it actually does work out and I think it works out pretty good. Well, I think that does it. Thanks for hanging out. And I hope this helped..
Ratings & Reviews
Not even close to water tight
Very easy install. Love the finished product. Roughly 2 hours to install. I did install by myself and worked fine.
Had one on my other truck
Good to have one on this truck as well
Stopped working, will move 3 inches and then gets stuck
Product is so far so good. There is a screw holding the motor housing that seems tilted. Hopefully it won't be an issue down the road. Delivery was terrible as it was late and I needed this for work. I spoke to etrailer customer service which was unhelpful and not accommodating for additional accessories I was looking to purchase.
