  • Recommended Tonneau Cover for a 2022 Ram 1500 Short Bed
    Hey Jim, great question! Aluminum is definitely going to be the most durable and theft proof between the two. Something like the BAKFlip MX4 Hard Tonneau Cover # BAK448227 would work perfect for you. This is a tri-fold, aluminum tonneau cover that when folded up give you entire access to your bed. I have dropped a picture in this answer with it folded up all the way so you can get a better idea of what I'm talking about! If you need help with anything else, please feel free to drop a...

  • Which Adarac Truck Ladder Rack is Compatible with the BAK Bakflip MX4
    I do have a solution that will allow you to use the BAKFlip MX4 on your 2020 Ram 1500, but the Adarac Custom Truck Ladder Rack # A70450 doesn't allow a hard roll cover to properly roll up because the arms are slanted inwards over the truck bed. Instead of the Adarac Custom, I recommend using the Adarac Pro Series # A4000965, since it is confirmed to work with a BAKFlip MX4. For the tonneau cover, the BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish # BAK448227 is the...

  • Will The Gator EFX Hard Folding Tonneau Cover Work With Adarac Ladder Rack On 2019 Ram 1500?
    It looks like you are referring to the Adarac Aluminum Series Custom Truck Bed Ladder Rack - Aluminum - 500 lbs # A76FR which is confirmed to fit your 2019 Ram 1500 with 6-1/2' bed. This ladder rack is designed to work in combination with inside-the-rail tonneau bed convers. The Gator EFX should work as long as it is mounted inside-the-rails on your truck bed. It looks like the Gator EFX mounts inside the rails similar to the BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish...

  • Fitment of the Thule TracRac SR with BAKFlip MX4 on a 2020 Ram 1500 Short Bed without RamBox
    While we do have a great solution for you, the Thule TracRac SR # TH57RV is problematic for a couple reasons when used with the BAKFlip MX4 # BAK448227 on your 2020 Ram 1500 (short bed without RamBox). Since you are absolutely correct that the BAKFlip's seals extends over the rails of the truck, they do interfere with the wide rails of the TracRac SR. Not only that, but since the TracRac SR has inward angles on the uprights, this causes rubbing against the sides of the panels when opening/closing...

  • Carrying 4 Kayaks on a Adarac Pro Ladder Rack With a 2019 Ram Short Bed and BAKFlip MX4 Tonneau
    You've done your research well. The Adarac Pro Series Custom Truck Bed Ladder Rack # A35WG will fit with the BAKFlip MX4 Hard Tonneau Cover # BAK448227 tonneau cover on your 2019 Ram 1500 and 5-1/2' bed. You will also be able to fit the Rhino-Rack 2 Kayak Carrier w/ Tie-Downs # S512-S512X to the Adarac crossbars using the Crossbar Adapters # KC-FK8

  • What Ladder Rack will Work with My BAKFlip MX4 Tonneau Cover on My 2019 RAM 1500?
    For a compatible ladder rack that works with the BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish # BAK448227 (for the 5-1/2 foot bed without Rambox) and # BAK448223 (for the 6-1/2 foot bed without Rambox), I recommend the Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars - 500 lbs # A70450 (for 5-1/2 foot beds without Rambox) or the # A70480 (for 6-12 foot bed without Rambox). Since the BAKFlip MX4 attaches inside of your bed's rails, the Adarac Custom...

  • How To Carry Bike Rack With 2021 Ram 1500 When Towing Travel Trailer
    I have another option for you, but since the BAKFlip MX4 Hard Tonneau Cover # BAK448227 you have on your 2021 Ram 1500 does not have the t-tracks for cross bars there is not a bike rack that will be able to be installed above the bed of your truck. Instead I recommend using the Curt Multipurpose Ball Mount with 2" Receiver for Bike Racks and Cargo Carriers # D210 which will allow you to tow your travel trailer and and carry a bike rack at the same time. The # D210 has maximum tongue weight...

  • Will TracRac SR Ladder Rack Fit with BAKFlip MX4 Cover on a 2021 Ram 1500 5-1/2 Foot Bed
    The Thule TracRac SR # TH57RV will fit with both the Cantilever Extension # TH24002XT and the BAKFlip MX4 Hard Tonneau Cover # BAK448227 for your 2021 Ram 1500 5-1/2' bed (without the RamBox). This is a great combination and we have confirmed that the cover will fit great with the ladder rack without any issues. Please note that the MX4 cover won't fit if you have the Multi-Function Tailgate. When it comes to a J-Style kayak carrier you can use the Thule Hull-A-Port Aero Kayak Carrier...

  • Will 2019 Ram 1500 Ladder Rack Fit With Gator Folding Tonneau Cover
    From what I was seeing it looks like the Gator tonneau cover on your 2019 Ram 1500 mounts on top of your bed rails so if you're wanting a rack for cargo we'll either need to go with a roof rack or go with a different tonneau cover that is compatible with a ladder rack. For a roof rack I recommend the Thule WingBar Evo which uses the following: 60" WingBar Evo Crossbars - # TH711520 Evo Clamp Feet - # TH710501 Fit Kit - # TH145199 Lock Core Kit - # TH450400 For a new tonneau cover and...

  • Does BAKFlip MX4 Hard Tonneau Cover for 2019 Ram 1500 New Body Style Have Automatic Latching Panels
    The BAKFlip MX4 Hard Tonneau Cover # BAK448227 that fits your new-body style 2019 Ram 1500 with a 5-1/2 foot bed is the latest version of this tonneau cover. What it actually has are panels that latch in place automatically when they are lowered, which is what I believe you were referring to. This means when you lock the tailgate on your '19 Ram you will have a secure truck bed to keep its contents safe. The MX4 is a complete no-drill installation which is great for your truck; it will...

  • 2024 Ram 1500 5-1/2' Bed Tonneau Cover and Ladder Rack Recommendations
    The design of the Leer Latitude Soft Tonneau Cover # LE28FR won't fit with a ladder rack on your 2024 Ram 1500 5-1/2' bed, but we do have some other similar options that will work together. There aren't any soft fold-up covers that fit with a ladder rack so I recommend going with either the TruXedo Pro X15 Soft Tonneau Cover # TX1485901 or the BAKFlip MX4 Hard Tonneau Cover # BAK448227 and pairing it with the TruXedo Elevate Truck Bed Rack System # TX96NV for the ladder rack.

  • Ladder Rack And Tonneau Cover Options For A 2023 Ram 1500 5.5' Bed
    The Thule TracRac SR Sliding Truck Bed Ladder Rack # TH57RV would be a compatible fit for your Ram and for the BAKFlip MX4 Hard Tonneau Cover # BAK448227. It unfortunately only comes with 69-1/2" crossbars, so it's 2-1/2" shorter than you were looking for. Out of the available options that are compatible with the MX4 this is longest crossbar option with the next size being 68". If longer crossbars are a must then you could go with a Yakima OverHaul HD Ladder Rack, which has interchangeable...

  • Recommended Ladder Rack for a 2023 Ram 1500 w/ a MX4 Tonneau Cover and a 5-1/2 Foot Bed
    Yes, there is. Since your Ram 1500 has the BAKFlip MX4 item # BAK448227 you will want the TruXedo Elevate Truck Bed Rack System item # TX96NV. I checked with our vendor and this ladder rack is confirmed to work with the MX4 covers. It mounts to the top of your bed rails instead of inside like most ladder racks and where your cover mounts. The TruXedo Elevate Truck Bed Rack System item # TX96NV has a 500 lbs capacity. The bars are 3-3/4" wide x 1-1/2" tall. The uprights are adjustable...

  • Recommended Ladder Rack and Tonneau Cover for a 2019 Ram 1500 5-1/2 Foot Bed
    In order to mount both a ladder rack and tonneau cover together on a 2019 Ram 1500 you will be limited in your selection due to the general mounting location of both components. However, I have an excellent option for you in the Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000965 paired with the BAKFlip MX4 Hard Tonneau Cover part # BAK448227. The Adarac Pro Series Ladder Rack mounts in the stake pocket and has vertical uprights whereas the BAKFlip Tonneau Cover mounts inside...

  • Will The Thule TracRac Base Rails Work With A 2020 Ram 1500 Short Bed And A BAKFlip Tonneau Cover?
    I do have a solution for you, but the Base Rails for Thule TracRac SR Sliding Truck Bed Ladder Racks # TH21782 will not work with your 2020 Ram 1500 short bed. Instead, I recommend going with the Adarac Pro Series Custom Truck Bed Ladder Rack # A4000965 which will work with your BAKFlip tonneau cover, like the BAKFlip MX4 Hard Tonneau Cover # BAK448227. This rack is made in the USA, has a maximum capacity of 500-lbs, and also has a tie-down kit # A4000882 so you can quickly and easily...

  • Which Ladder Rack Is Compatible With BAKFlip Mx4 Tonneau Cover On 2021 RAM 1500 Short Bed?
    There is a version of the Rapid Switch Ladder Rack that is compatible with your 2021 Ram 1500 short bed with BAKFlip MX4 Hard Tonneau Cover - Folding # BAK448227, but the one you were looking at is not it. You will want to go with Rapid Switch Systems Pro Sport Ladder Rack - BAKFlip Tonneau Covers - Full-Size Short Bed - 500 lbs # RS69FR which is compatible with your setup.

    In order to use both a tonneau cover and ladder rack together on a 2020 Ram 1500 with 5-1/2' bed you only have a few options. The Adarac Custom Truck Bed Ladder Rack part # A70450 or Adarac Aluminum Series Custom Truck Bed Ladder Rack part # A4001235 will work with any soft roll-up tonneau cover that mounts inside the bed rails like the TruXedo Lo Pro Soft Roll-up Tonneau Cover part # TX585901. The Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000965 will work with both soft and...
