Almost Perfect

Excellent cover and I love the design. Installation was easy and my only complaint is that it came with a broken driver’s side end cap. Excellent customer service got me two compete sets of end caps ASAP.

Shipping damage

Ordered the new X4s. The first one arrived with one of the cover joints disengaged. Warranty replacement was fast. Unfortunately, the second one arrived with the same problem. Warranty replacement was even faster. The third cover was from from damage. I really like the design features of this improved version of the X2, which I previously had for 5 years.

TonneauCovered, YES, BAK, NO

Tonnoeau Covered provide a great deal and excellent communication. They are great people to work with. BAK, on the other hand, leave a lot to be desired..
The Revolver 4Xs is a good looking cover. The locking mechanism is awesome.
The install on a Gladiator, honestly, sucks. I helped 2 friends install theirs. One was on a21 F-150 and the other on a 2019 Ram 1500. So easy! Just line them up and clamp them on! Not so for a Gladiator. Set aside a whole morning or afternoon for your install. I have no idea why the Jeep install cannot use the same, quick and easy clamp system as the full sized trucks.
There is a kink, bump, imperfection in my cover that looks terrible. There is no return on a BAK product as soon as you open the package and BAK will not answer emails or give any substantive answers over the phone. The fact that they give a 5 year warranty means nothing if they will not offer a solution for an out of the box issue.
If you want a good deal, go to TonneauCovered. If want good warranty service, buy something other than BAK.

Revolverx4s RAM w/ Rambox

Cover is great. Cual IRU is amazing and it has the best of the 2 world , is hard and protect but it retractable and allow you to use the entire box.

Unfortunately my came with missing screws that tight the front of the cover. And service has been hard to get the replacements part even after sending picture and video they have not reply with shipping or at least screw measurements so I can purchase them. This is the only down side. Hope that yours come completely if not you going to have nightmares
