In this in-depth review, we are going to talk about the Bakflip MX4 Tonneau Cover from BAK Industries. A rolling soft bed cover will provide easy access to your truck bed. But offers no security and is not the kind of product that many folks want to add to their expensive pickup truck.

However, a traditional hard tonneau cover, whether it tilts, folds or retracts will always provide great security and even looks. But unfortunately, most will never allow you full access to your truck bed. That’s why BAK Industries created the BakFlip MX4 Tonneau Cover.

Its patented design ensures that you get the best of all worlds. Great looks, great security, full truck bed access, and the most cutting-edge tonneau cover design and styling available anywhere in the world.

Best of all, the MX4’s patented design offers the world’s most convenient hard folding tonneau cover that guarantees access to your entire truck bed.

How to drive with the BakFlip MX4 tonneau cover open

BakFlip folding tonneau covers are all equipped with powder-coated D-rings on top of the cab panel as well as under the tonneau panels. These are visible when you fold the panels over. The D-rings allow you to anchor your panels down in incremental positions.

There’s a patented swiveling arm integrated into the rail system of the MX4, which enables you want to drive your truck with your bed cover completely open. These swiveling arms rotate forward and prop the tonneau cover-up.

There’s also a specially designed sliding component which allows you to lock the swiveling prop rods against the BakFlip MX4 bed cover. This allows you to drive at freeway speeds without any worry of the tonneau cover flying off the truck or vibrating loose.

Installation and Design

The BakFlip MX4 hard folding tonneau cover is cut specifically to follow the shape and contour of your truck bed. This has a huge impact on the ease of installation. Since the MX4’s rails clamp directly to your truck bed rails, all you need to do is drop the folding tonneau cover onto the truck between the rails.

There’s virtually no modification or manipulation required on your truck as the MX4 always fits perfectly. The patented flush-mount design of the MX4 is the choice of installers worldwide! This because BakFlip tonneau covers follow factory contours for a perfect fit.


BakFlip tonneau covers are comprised of a series of panels that are connected to each other with seamless rubber hinges made from EPDM. The MX4 rubber hinges cannot corrode in extreme temperatures and can be folded back and forth for years without any noticeable wear at all.

Unlike piano hinges or metal hinges that can leak, corrode or rust, the BakFlip tonneau cover’s patented hinge system is completely resistant to all temperatures and the most torrential weather conditions.


BakFlip tonneau cover panels are laminated by either impact-resistant FRP or rugged aircraft-grade aluminium. After the tonneau cover panels are crafted to the correct size they are framed with a patented aluminum frame.

That renders BakFlip tonneau covers the strongest folding tonneau covers available anywhere in the world.

The frames around the panels are also the receptacle for the rubber hinges that simply slide into the panel frame with a unique tongue and groove design. The panel frames act as a double insurance against any possible water from penetrating or bypassing a hinge.

BakFlip MX4 panels cannot be cut with a blade. Even though the hinges are rubber, they are encased from the underside in solid model and can therefore also not be penetrated with a knife or sharp blade.

Locks & Latches

BakFlip MX4 hard folding tonneau cover latches are concealed under the BakFlip panels so that they are never exposed to the elements or the prying eyes of potential thieves. Rain, snow, dust, sand, and any other contaminants are no match for the MX4!

The ingenious design of the BakFlip’s latches allows the panels to be anchored down automatically. In addition, the latches are designed to engage the rails, merely by shutting your tonneau cover.

BakFlip tonneau models with 3 folding panels have latches under all panels. BakFlip’s with 4 folding panels have latches under the first, third, and fourth panels. Releasing the MX4 BakFlip’s latch is as easy as tugging on a release cable from either side of the truck.

You never need to climb into the truck or worry about additional aftermarket keys. In most instances, the key you drive with is the key you lock the BakFlip tonneau cover with.

Weights and Measures

MX4 BakFlip tonneau covers are available for almost all makes and models of domestic and international pickup trucks. Needless to say, BakFlip tonneau covers for long bed trucks are larger than BakFlip’s designed for small double cab pickup trucks. As such, some BakFlip tonneau covers ship in one box and some ship in two boxes.

All BakFlip folding tonneau covers are comprised of 2 primary parts:

  1. The actual folding tonneau cover top
  2. The tonneau cover rails.

When the truck bed is shorter than 6’ the tonneau cover and rails always ship in one box.

When the pickup truck bed is longer than 6’ e.g. a Full Size Short Bed Truck like a Ford F150 extended cab, it will ship in 2 boxes. One box for the tonneau cover and one for the rails. The average aluminum folding tonneau cover weighs approximately 50 lbs.
