Anybody running an BAK X4s on a short bed Sierra?  I am thinking about buying one.  I would be interested to know your thoughts about performance, installation, and tightness.  Also, did you have to remove grab handle on the inside of the bed and can the the cover be operated with the tailgate in any position?

Thanks

I've got this on the carbon bed.  Really good attention to detail and smooth operation.  No problems closing with the tailgate in any position.  Grab handle does not interfere.

Put one on mine a few months back love it great fit easy install. Works with grab handle and multi-gate. Plus it does NOT cover the third brake light so if you have bed/rear camera it still works when open up against cab.

I have had one for about 5-6 weeks and really like it. The folding ones block the rear window and brake light as stated above. I have had the canister ones and while loosing 8-10 inches is no big deal with an 8' bed I did not want to give that space up in a 6.6 bed and I really would not want to in the really short beds that most of you all have. 

 

The other nice thing is how flush it sits. I would guess its only about 1/8 inch above the rails. and takes up hardly any bed space. The only down fall if it is one is that it is either open or closed and there is no middle ground but it is a small price for such a great cover. 

 

Install is easy as well.

I purchased one from dealer when buying my 2020 Silverado LB a couple years ago. Open/close/latch is done with tailgate open, which somewhat secures it. 

Pros: Looks Awesome,  easy to use and maintain.  For partial loads, I string a rope thru the middle & secure it.

Cons:

Plastic buckles on retaining straps, when open, can break easily due to angle of latch. One of mine broke the first time I tried to latch. Dealer did replace under warranty. Just have to be cautious. 

Too much water intrusion at front corners. I live in Western Washington,  so get nice winter rains. Dealer reinstalled it and while intrusion slowed some, still frustratingly much.

When wet inside bed, condensation forms inside on the aluminum,  contributing to more moisture and the felt can then get wet. All this can then freeze. 

You must keep the track part of rails and bottom of cover that sits in track lubed (silicon) during times of winter rain/freeze weather we get here, otherwise you cannot open the cover till the track thaws. 

Black cover/Aluminum construction has high thermal loading which can burn during summer if not careful. 

Overall, I like the cover for looks, security and ease of operation.  I get frustrated with the water intrusion,  and incorporate it into my planning.

Eugene Walsworth,

 

You have the X4. The cover has been updated and is now the X4S. The way the plastic buckles attach has been fixed and works very well now. There are no longer any felt pieces to get wet as well as a few other improvements.

 

I cannot test to water entry until we get our winter rains but so far it seems about normal. No cover is water tight but if it keeps the bulk out and is mostly around the tailgate and front of the bed where it will drain is about all you can wish for from any cover.

I have the MX4 on my '21 Sierra AT4 with Carbon Pro bed.  When opened up, it does cover the rear window, but not the brake light or camera's mounted there.  I flip the rear view mirror to camera mode and all good.  My observation is the panel next to the cab that does not fold is a little wider than previous having the folded panels at more of an angle against the cab and possibly lower overall.

I have the x4s on my 21 AT4 short bed. I am currently on my 3rd cover since may, the first 2 came apart at the seams. So far truck hero has replaced them no problem. They swear the problem in manufacturing has been corrected

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
