  • Recommended Folding Tonneau Cover and Truck Bed Bike Rack for 2024 GMC Sierra 2500 Denali Ultimate
    Hi Richard; I'm assuming you want a hard folding tonneau cover for your 2024 GMC Sierra 2500 Denali Ultimate. Assuming that is correct, I recommend the BAKFlip MX4. If you have the 6-3/4' bed you need the # BAK448133 and for the 8' bed the # BAK24FR. Then for a truck bed bike rack we have the Saris Traps Fork-Block 3 Bike Rack # SATRK33-BLK3. This sits on the floor so it won't require permanent installation and it won't interfere with the tonneau cover when it is open. We don't have a...

  • How Thick is BAKFlip MX4 When Folded on Front Panel
    Hey Phil! The BAKFlip MX4 Hard Tonneau Cover # BAK448133 is approximately 3" thick when folded onto the front panel up at the cab of the truck. The panels are 1/2" thick but they don't fold perfectly flat and there is some other material in there as well. If you count where the latches sit it is closer to 4-1/2". Will that work for you? If not, you might want to consider a retractable cover like the Pace Edwards Switchblade # PE63CV.

  • Choosing Between Leer and BAK MX4 Tonneau Cover for 2024 Chevrolet Silverado 2500
    Hi JD; if I had to choose between the Leer Hard Tonneau Cover # LE67FR and BAKFlip MX4 # BAK448133 I would go with the MX4. As far as security goes both are locking covers so it will be about the same between the two. The MX4 has seals and drain tubes while the Leer only has seals. For the warranty, BAK offers a 5-year warranty compared to a 3-year from Leer. I'm not sure how either of them responds to warranty issues but I can tell you when we have questions about products that require...

  • Comparing The BAKFlip F1 And BAKFlip MX4 For The 2020 GMC Sierra 2500 With 6-3/4 Bed
    The BAKFlip F1 Hard Tonneau Cover - Folding - Aluminum and Fiberglass # BAK772133 and BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish # BAK448133 are very similar but there are a few minor differences. The F1 has a rough texture that tends to hold up better against various conditions and does not get easily scratched or dented. The MX4 has a smoother appearance and texture and does not have a rough look or feel to it. I think the F1 looks better and it holds up better...

  • Is BAKFlip MX4 or F1 Tonneau Cover Better for 5th Wheel on 2022 Chevy Silverado 3500 Short Bed
    While there are minor differences between the two BAKFlip tonneau covers for your 2022 Chevy Silverado 3500 with a 6-1/2 foot bed, for the purposes of using either cover when towing a 5th wheel, there is no real advantage with either the BAKFlip MX4 Hard Tonneau Cover # BAK448133 or BAKFlip F1 Hard Tonneau Cover # BAK772133. The biggest difference between the two is that the F1 has more robust panels, made out of a reinforced polymer (a type of plastic designed for durability) and measuring...

  • Would BAKFlip MX4 Tonneau Cover Block Third Brake Light Camera of 2024 Chevy Silverado 3500
    With the BAKFlip MX4 # BAK448133 installed on your 2024 Chevy Silverado 3500 short bed it would block the third brake light camera when folded up but I do have a solution that would work. Instead you would want to go with a retracting tonneau cover like the part # PE63CV which would give you access to the bed for your gooseneck hitch and allow you to use camera.

  • Thule TracRac SR Compatibility With BAKFlip MX4 Folding Tonneau Cover
    Technically, the Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever - 1,250 lbs, part # TH44RE, will fit your vehicle with the MX4 tonneau cover. But you will have to shift the uprights of your ladder rack anytime you open your tonneau cover. The overlap of your BAKFlip MX4 Hard Tonneau Cover - Folding - Aluminum - Matte Finish, part # BAK448133, is not the reason the Thule TracRac SR is not the best fit for your 2022 Chevrolet Silverado 2500. Your tonneau cover is a tri-fold....

  • Do the Truck Hero TS Rais Work with the Gator EFX Covers
    Yes the TS Rails for Truck Hero Elevate Rack System part # TH65FR will work out well with your Gator EFX Tonneau Cover. The design of the Gator EFX is very similar to that of the BAKFlip MX4 Hard Tonneau Cover part # BAK448133 which is confirmed to fit with the TS Rails.

  • Recommended Tonneau Cover For a 2024 GMC Sierra 2500 Compatible With Thule TracRac Ladder Rack
    I recommend installing the BAKFlip MX4 Hard Tonneau Cover on your 2024 GMC Sierra 2500. You will need either the 6-3/4' # BAK448133 or 8' # BAK24FR cover depending on your bed length. These covers will fit the Thule TracRac which fit the SR rails. If you have a TracRac TracONE # TH27000XT style ladder rack you will need the following components to convert it to fit the SR Rails. Modular Base LF/RR # TA01-42003 Qty 2 Modular Base RF/LR # TA01-42004 Qty 2 Knob # TAKB-90030-1 Qty 4 Nylon...

  • Ladder Rack Recommendation for a 2023 GMC Sierra 2500 with a BAKFlip MX4 Cover
    Technically, yes, the BAKFlip MX4 Hard Tonneau Cover and TracRac SR Ladder Rack (with the Cantilever) will fit together on your 2023 GMC Sierra 2500: - BAKFlip MX4 Hard Tonneau Cover # BAK448133 - Thule TracRac SR # TH94RE - Thule TracRac SR (w/Cantilever) # TH44RE The reason this isn't a definitive "yes" is while the tonneau cover will be able to open (you might have to shift the uprights of the rack to accomplish this), the rubber seals on the sides of the BAKFlip MX4 panels will...

  • Differences Between BAK BAKFlip G2 and MX4 Hard Folding Tonneau Cover for 2022 GMC Sierra Short Bed
    In a nutshell, the MX4 part # BAK448133 is of a slightly higher quality than the # BAK226133 G2. The MX4 has a 5 year warranty versus the 3 year for the G2. The MX4 has a matte finish that does a better job of hiding imperfections and scratches than the gloss finish used on the G2, and the MX4 just feels a bit more substantial as if it'd hold up a bit better over time. Also, the rear seal of MX4 allows you to close the tailgate whether the tonneau is open or not. With the G2, the tonneau...

  • Comparing The BAKFlip MX4 And FiberMax HArd Tonneau Covers For A 2024 GMC Sierra 2500
    Hey Deen, I've listed out the main differences between the BAKFlip MX4 Hard Tonneau Cover # BAK448133 and BAKFlip FiberMax Hard Tonneau Cover # BAK1126133 below: The MX4 has a matte-black finish whereas the FiberMax has a textured, gloss-black finish. The dual-action tailgate seal on the MX4 allows you to close your tailgate whether the cover is open or shut. The flap seal on the FiberMax overlaps your tailgate, so the tailgate needs to be shut before the cover is closed. The fiberglass...

  • What is the Difference Between the BAKFlip G2 and MX4 for 2020 GMC Sierra 3500 Short Bed
    The main difference between the G2 # BAK226133 and the MX4 # BAK448133 is that the MX4 can remain latched in position when latching the tailgate. With the G2 the cover must be unlatched to latch the tailgate. This can become kind of a pain if you're leaving the cover in position for an extended period, but constantly at the tailgate. The G2 also has a glossy finish on it, while the MX4 has more of a matte finish and is generally a more sturdy cover when it comes to holding up over time. At...

  • Rapid Switch Pro On A 2021 GMC Sierra 2500 HD with 610 bed with Bakflip MX4
    The BakFlip MX4 is compatible with the Rapid Switch Ladder Rack # RS77FR. These systems work well together and the Rapid Switch System is the same for the 8 foot and 6-3/4 foot bed. For your tonneau cover, it all depends on the length of your bed. If you're wanting to get the BakFlip MX4 and you have a 8 foot bed, get this one # BAK24FR and if you have the 6-3/4 foot bed get this one # BAK448133. The rails are long enough to go from the bulkhead of the bed to the tailgate. I have an installation...

  • Does BAKFlip MX4 Tonneau Cover For 2022 Chevy Silverado 2500 Standard Bed Fit w/ Adarac Ladder Rack
    Yes, the BAKFlip MX4 tonneau cover is absolutely compatible with the Adarac Aluminum Series ladder rack on your 2022 Chevy Silverado 2500. The correct part numbers for the cover and rack that fit your truck are the following: - BAKFlip MX4 Hard Tonneau Cover # BAK448133 - Adarac Aluminum Series Custom Truck Bed Ladder Rack - Aluminum Finish # A4003992 or Matte Black # A36HG The MX4 installs inside your Chevy's bad rails, while the Adarac uses the stake pocket mount on top of the bed...

  • Tonneau Cover that Fits 2012 Ford F-250 Long Bed with Tool Box Flush with Rails
    Hey Sam, since you have a tool box that is flush with your bed rails you would want a tonneau cover that sits on top of those rails so that it would fit with the tool box. For that we have the Extang Trifecta part # EX92725 which is a confirmed fit for your truck. The BAK you mentioned would not work for this purpose.

    The Rightline Truck Bed Tent # RL110730 attached more to the outside of the bed so you'll have no issues using it on your 2022 GMC Sierra 3500 in conjunction with your BAKFlip MX4 # BAK448133 tonneau cover.

  • Adarac Ladder Rack Compatible With The BakFlip Mx4 Tonneau Cover On A 2021 Chevrolet Silverado 2500
    If you have the BackFlip MX4 # BAK448133 tonneau cover on your 2021 Chevrolet Silverado 2500 then you can use the Adarac Pro Series Ladder Rack # A4003991. You will need to get this rack because the towers holding the crossbar up is completely upright. These only come in silver. This one comes in black # A4004148 but won't work because of the towers tapering inward. You will most likely have contact with your first panel on your tonneau cover with the tower when you're folding it up.
