Warranty

Normal wear, accidents, misuse, improper installation, and modifications fall outside the warranty. Shipping fees for warranty service are the customer's responsibility.

this was a bigger purchase than i usually make online so i was a little hesitant. reached out first and Isaiah responded fast and was straightforward. that was enough for me to go ahead. cover came in perfect condition and fits perfect

D
Dillon Hartley

honestly just needed something solid for my truck and this did the job. ordered through truck bed barn, got a tracking number the next day, showed up without any damage. pretty much exactly what i was hoping for

T
Tommy Briggs

packaging was legit, not just thrown in a box. got it on my f250 without needing any help which was my main goal. shipping was fast and tracking updated regularly so i always knew where it was

R

Isaiah was super helpful when i reached out before ordering. had a question about whether it would work with my setup and he got back to me in a couple minutes. cover arrived on time, no complaints

Had an MX4 on my old F250 for 4 years and it never gave me a single problem. Sold the truck and bought a Sierra, and I ordered another MX4 right away. That's how good these are. Truck Bed Barn had a great price on it too.

Very Nice cover, pretty easy to install. The product recieved was close to the one shown on the link for installation. But still had some differences.

the mx4 is a premium cover and absolutely delivers on its promises. Will definitely buy my next cover from Truck Bed Barn.

M
Matthew Foster

cover fits well and I have to mention that Liam was super helpful on customer support when I called in to confirm stock before ordering

E
Eric Bennett

My package shipped the same day I ordered and when it arrived it only took me about 1 hour to install. Liam helped me confirm fitment on my cover. thanks again!

R

This is my second BAKFlip cover (had an older G2 on my last truck). The MX4 is a massive upgrade. The matte finish looks much better and doesn't show fingerprints or smudges. Holds up well to the desert heat.

T
Thomas Gray

Took about an hour to get it perfectly aligned but it looked great after it was installed. No complaints here.

K
Kevin Peterson

the mx4 fit my truck perfectly. Also Isaiah at Truck Bed Barn was super helpful getting my order tracked down when the carrier delayed it (still got here in 3 days)

J
John Campbell

the mx4 feels incredibly durable and gives me a little more peace of mind when leaving valuables in the bed. Truck bed barn helped me out with fitment so shout out to them.

A
Alex Mitchell

You get what you pay for. Liam was super helpful answering my questions before I pulled the trigger and they confirmed fitment for the mx4 on my truck.

S
Steve Harrison

Overall, the BAK MX4 is a beast. I do get a tiny bit of water near the tailgate corners in heavy thunderstorms, but nothing that actually ruins my gear. Still the best hard folding cover on the market plus shipping was quick

B
Brian Lewis

The install instructions for the mx4 were actually pretty clear and was easy to install. shipping from Truck Bed Barn was incredibly fast it only took 1 and a half days. highly recommend.

C
Chris Wallace

Fits my Colorado perfectly. I do a lot of driving on dirt roads and it does a fantastic job keeping the dust out of the bed. Folds up easily when I need to throw my dirt bike in the back. Huge shoutout to Isaiah he was super helpful making sure I got the exact right part number for my specific bed length.

M
Michael Torres

Fits well, Isaiah helped me confirm my fitment and they had the best price out there!

D
Dave Sullivan

Looks good and the low-profile look is exactly what I wanted. Liam helped me confirm the fitment on my truck and customer support was easy to deal with.

J
Jason Reynolds

I’ve had a few soft roll-up covers before, but upgrading to the MX4 was the best decision. The aluminum panels feel incredibly sturdy. I love that I can fold it all the way to the cab when I need to haul larger tools

M
Mark Davis

Installed this on my in about 45 minutes. It rained hard the next day and the bed was bone dry. Very impressed with the build quality. Liam on customer support was also super helpful when I had a question about the drain tubes.

3rd BAKFlip I've owned. This one is the best yet. Gasket on the side is way beefier than my old MX4. Latches feel better too. 5 year warranty is nice. Can't go wrong.
