BAKFlip MX4 for RAM 1500 DT 6'4 Bed without RamBox by BAK Industries

The BAKFlip MX4 for the RAM 1500 DT Big Horn is a hard folding tonneau cover made for the 6'4 bed without RamBox. It keeps the tub covered and your gear out of sight, and the aluminium panels fold forward toward the cab when you need the space. You can drive with two-thirds of the bed open or fold it all the way up for full bed access.

A full matte black finish runs across the cover, with matching cab corner caps, clamps and elevator bolts for a clean, factory-style look on the RAM. Pre-moulded, die-cut bumpers protect the cover when it's fully opened, and upgraded prop rod clips hold it tighter when it's up.

It installs with no drilling and supports up to 181kg (400lb) of evenly distributed weight. EPDM seals, upgraded seal end caps and a multi-function tailgate seal work to keep water out, drain tubes are included, and it's made in the USA.

Features

  • Aluminium panel construction: a hard lid over the tub that folds in sections toward the cab.
  • Full matte black finish: carried through to the cab corner caps, clamps and elevator bolts for a streamlined look.
  • Drive with 2/3 or full bed access: the panels fold toward the cab, giving full bed access in seconds.
  • Upgraded prop rod clips: a tighter, more secure hold when the cover is open.
  • Pre-moulded, die-cut bumpers: protect the cover when it's fully opened.
  • EPDM seals and upgraded seal end caps: built for maximum water resistance around the cover edges.
  • Multi-function tailgate seal: closes the gap at the rear of the tub.
  • Upgraded mounting rail end caps: a clean, finished look along the bed rails.
  • No-drill installation: the cover installs with no drilling required.
  • 181kg (400lb) load rating: supports evenly distributed weight across the closed cover.

Frequently Asked Questions

Which RAM 1500 does this BAKFlip MX4 fit?

This version is for the RAM 1500 DT Big Horn with the 6'4 bed without RamBox. The 5'7 bed and trucks with RamBox use a different MX4, so check your bed length and tub setup before ordering.

How much weight can the BAKFlip MX4 hold?

It supports up to 181kg (400lb) of evenly distributed weight when closed. That's a cargo rating, not a step rating, so avoid concentrating weight on one panel or standing on the cover.

Can I drive with the BAKFlip MX4 open?

Yes. It can be driven with two-thirds of the bed open or with the panels folded all the way up for full bed access. The upgraded prop rod clips hold the cover when it's upright.

Do I need to drill my RAM's bed to install it?

The cover installs with no drilling. Drain tubes are included, and drilling may be required to fit them on some models. Refer to BAK's installation instructions, or have a qualified installer fit it if you're unsure.

Why does a BAKFlip MX4 leak, and how does it keep water out?

The MX4 uses EPDM seals, upgraded seal end caps and a multi-function tailgate seal to keep water out around the edges, with drain tubes to carry water away. Like most tonneau covers, it's designed to reduce water entry rather than make the tub watertight, so fit the drain tubes and check the seals periodically. Pack gear that must stay dry in sealed containers.

Will the BAKFlip MX4 block the RAM's third brake light?

BAK notes that some 8' bed applications may not allow third brake light visibility because of cab height and light location. This listing is for the 6'4 bed.

Where is the BAKFlip MX4 made?

The BAKFlip MX4 is made in the USA.

Running the shorter tub instead? There's a BAKFlip MX4 for the RAM 1500 DT 5'7 bed, plus a 5'7 version for trucks with RamBox. You can also compare every cover in our RAM tonneau covers range or the full tonneau cover collection.

Why Shop With Us

Why Shop at 4x4 Down Under?

We know that you have a lot of options out there, and we’re incredibly grateful that you’re considering spending your hard earned money with us. We like to think we stand out from the crowd in a few ways.

Excellent & Honest Service

We try and provide the best pre and after sales service possible. If you have a question we’re here to help, and if we don’t know the answer we’ll tell you and then do our absolute best to find the answer for you. We’re also here to guide you to the best possible outcome for you. A lot of stores will simply try to up-sell you on the most expensive option. That’s not how we operate. We want to build a relationship with our customers, and the only way to do that is by being honest and direct.

4x4 Down Under is built on honesty and integrity. For example when you make a purchase with us we only charge your account once we confirm the product is ready for dispatch. Although we like to guarantee everything on our store is available we’re not perfect and mistakes do happen. If something turns out to not be available we’ll let you know immediately and you have the option to cancel your order or wait for more stock to arrive. Should you not want to wait the order is voided, and there’s no waiting a week to get your money back (it’s instant!).

Aussie and Proud!

We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors. Nothing is imported directly and we don't stock any grey imports. This also means that all manufacturer warranties are fully honored by the brands themselves.

No Sales Gimmicks 

When you shop at 4x4 Down Under you don’t have to worry about:
  • Annoying and dishonest ’Sales Timers’ that simply reset every few hours and are there to coerce you into buying.
  • Dishonest “low stock” labels, another coercive sales gimmick.
  • False “John just bought a…” alerts. Our customer alerts (bottom left) are 100% true and we're proud of them.
  • Being bombarded by trust badges and labels everywhere you look that mean nothing. 
  • We don't spam! Your information is safe with us. It will never be shared or sold, or used to fill your inbox with garbage.

Fast Shipping with Insurance!

We've partnered with some of Australia's best couriers and freight agents to ensure your purchase reaches you in super-quick time. Once your order has been dispatched you'll receive tracking information which will allow you to track your order online every step of the way. And if something should happen to your order while in transit you can rest assured that it's insured and you won't lose a dime!

If you still have any doubts feel free to give us a call on 1300 76 86 41, or contact us here. We'd love to hear from you.
