Whether you’re loading your truck up with sand, cement, or concrete, or packing up for a weekend camping trip, your cargo needs to be protected, and your truck deserves to look good.

Not only do the enhanced heavy-duty aluminum panels look great in their flat matte finish – they also provide incredible resistance to scratches and UV rays. In addition, the premium density foam core stands up strong to heavy use and abuse. The newly upgraded rear seal is universal, and allows you to close your cover while the tailgate is in the open or closed position - no need to worry about damaging your cover when you close the cover in a hurry. Now, new and updated features include include Matte elevator bolts, prop rod clips, rail end caps, and finished cab corner caps.

Your BakFlip MX4 Aluminum Tonneau Cover is rated to hold up to 400 lbs of evenly distributed weight right on top. The latch housing is injection molded, for supreme durability that will last for the long haul. This cover is made in the USA and backed by a 5-Year Warranty.

Optional Upgrade: Choose the Standard BakFlip MX4 model, or maximize your truck bed's functionality by adding the optional BakBox Folding Toolbox. This truck toolbox is strong, lightweight, easy to handle, and works seamlessly with the BakFlip MX4. (BakBox not available for all vehicles.)

Very good quality cover but they did leave lots of aluminum chips from the drilling they did during fabrication. Also, the part that sits over the tailgate is not exactly flat so will likely leak in the middle of the tailgate. I do like the latches and cover but they need a little more QC for a nearly $1,000 dollar cover.

Great product, repeat customer had one on my last truck. Love the hidden latches and the clean appearance when closed. Lots better than a roll up style since you don’t lose so much space in the front of the bed. Really like the improved catches for the full open prop rods. Definitely will recommend this product!

I bought this BAK4 cover for a 2020 Honda Ridgeline. My son and I installed it today. We are both experienced with all things mechanical. It took us about 3 hours to figure it all out and complete the installation. The online videos are helpful but it takes longer to do than I expected, however, we wanted a 1st. class job and took our time to make sure everything fit just right. I feel this cover will provide more security for items in the bed of the truck. That is the only reason I would buy this cover instead of the Access roll up model that is on my other truck.

Robust construction. Well engineered and carefully fabricated. Perfect fit on our 2020 Toyota Tacoma. Water tight fit and provides reliable security to contents in truck bed. Best product for the money. Would buy same again. Very worthwhile investment all the way around.
