I searched around and found a bunch of helpful hints to install these since they do not come with any install information at all. You will need a large torx bit to remove the 6 oem screws and you will reuse 4 screws and 4 plastic washers per side. Next glue the 4 plastic washers to the center 4 holes leaving the front and back holes out. I used the same setup for both the front and back holes which was a M6 1.0 20mm or 25mm flat head screw (my Home Depot was out of the 25mm), 1/4 in x 1 in large washer, small M6 flat washer and the nylon washer from the oem screw last. I tightened these as tight as I could get them and took my time slide on the new rail ensuring the back hole is in 1st then the front on until the center holes line up.

Since these are factory installed parts there are technically no installation instructions. However here are some links to JeepGarage.org where a forum member shows you how to install these rails if your Jeep didn't come with them.

This product was a perfect fit to replace my original non-functional rails. I have added a yakima rack and it is perfect. Thank you to Just for Jeeps for sending me a link on installation to help.

All of the other comments are accurate. Requires extra washers on front and real bolts in order for the rails to fit absolutely flush on both ends. For about $2 I was able to get them to bolt up perfectly and mount solid on my 2020 Latitude....love them!!

The forums will all tell you (very small gaps) front and back, that's true. No installation instructions stink, but they look great once on, You can follow my install tips on forum. Put these on a WK2020 Grand Cherokee Altitude 4x4, with Brightlines cross bars

Tip. Add some large washers to the front and rear bolts. Super glue them to the bolt head. You have to play with the height adjustment a little bit. Once you get it figured out they will sit flush and work great.

I love the black rails on my blacked out Altitude.

Perfect fit for my grand Cherokee high altitude. Many comments about installation and the front and back not fitting flush. Instead of messing with the friction/pressure fit design I simply drilled holes on the top, placed screws (had to get slightly longer for the front edge) and nice and snug. I’m not sure why it isn’t designed this way for a very simple installation. I still need to modify and place the hole caps. Too shallow for the full depth. Again if originally designed this way, wouldn’t be an issue

I was told by the dealer this wouldnt work on my 2020 Jeep Grand Cherokee because all the roofs are different, that was not the case and all the holes line up perfect, but yes you do have to fiddle with the front and back only because it mounts with different hardware but there are tons of easy options including just using what you have with a thin washer and its done

I found these fairly easy to install, but you really would do well to order some stainless washer head screws to replace the 6mm mounting screws for the front and rear mounts. (order 4 screws from McMaster Carr or the like) The problem with reusing the existing screws is that you will need to add fender washers and file off most of the head on the front screws for them to fit. The end caps, front and rear, are plastic and the grove for the screw heads are slots with the front slots limited in height, thus the need to grind or file the heads down. The washer head screws would eliminate this and replace the need for fender washers.

As noted by most other reviewers, these were not designed to fit the non-Limited Jeeps. Getting them on to my Altitude edition required trying a number of different washers and a few hours of futzing around putting them on and taking them off to tweak the adjustments to get them flush to the roof. That said, once they are on, they stay there! I took a 500 mile trip with a giant cargo box attached without any problems.

Thanks for reaching out to me. I was able to install the roof rack and it is very functional, however the fit leaves something to be desired. Specifically - there is a gap between the rack and the roof even though the rack fasteners are properly tightened. Do you have fix for this situation?

Mopar Quality! it was an easy install. Part of the install required the part to come off a few times until the front bolts were adjusted to the right height. Used the wrench to give it the last turn to get it to the proper height and seal the leading edge of the rail to the roof.

Very happy!!

Arrived fast and exactly what was ordered. Easy to install.

I can now put racks on my Jeep, thanks to these railings! Couldn’t be happier.

Amazingly fast shipping and perfect fit and condition, best place online to buy Jeep parts

These work exactly as some of the reviews have stated. I added a larger washer to the front and rear bolts and with some time and patients got them to sit almost perfectly flush. Overall it took me about 45 mins to install and it's a solid tight fit.

These rails worked great on my 2018 Jeep Grand Cherokee High Altitude. The front and back bolt set for each rail needed to be adjusted to get the proper fit-up, but that was expected per everything I read on forums.

2018 GC High AltitudeWe bought this just a week before a trip we wanted to take our paddleboards on and didn't realize the stock rails were worthless. The rails arrived the day before our trip and I installed them with relative ease. As others have mentioned you have to play around with the height of the front and rear bolts. I found some washers with a slightly larger diameter laying around and added one to each of these bolts to achieve a nice interface for the underside of the rails to get a snug and flush fit.See the links Corey with Just for Jeeps posted as they are helpful. We've taken 2 boards on 2 trips now using the Thule SUP rack and the whole system is very solid and secure.

Such a small upgrade but has made a big impact on the overall look of my Grand Cherokee. I purchased these because the rails that originally came on my Jeep were not functional.

Too long to install cause had to make adjustments on the front and rear bolts height. Adjusted height to make plastic enclosure sit close to roof. Started w/ 1/4" gap and then 1/8" gap and finally perhaps 1/16". Had to remove front plastic clip cause the round bolt head made plastic enclosure sit 1/4" above roof.Anyway worth it cause now I can to install accessories. Don't know why f%^&*$ing Jeep did that however it was my bad for not noticing that.

Purchased these to replace the non-functional black rails on Jeep Grand Cherokee High Altitude edition. They look good and are solid. It takes a lot of trial and error to get It so there's little to no gap between the ends of the rails and the roof. I still can't get them completely flush, which is mildy annoying. There are some threads w tips but even then these haven't been the perfect fit (I may be the only one who notices the little space though). It would be nice if some install tips came with these, and also would be nice if the bolts and washers were included. They aren't, so make sure you save the ones that are with your existing rails. Once you figure these out, it takes only maybe 10-15 mins to install, including removal of the old rails. Again, I have no concerns about how solid they are and they look great. Only deduction is due to minor fit issue.

I really love these roof rails what a difference between SRT low profile rails and these ones thanks

Product is good solid product but needs to come with directions. It's simple once you figure it out but you have to figure it out first. Once they are on they look great and are very functional

I was a bit worried at first due to the comments about the 1/8" to 1/4" gap on the front end. Installation is simple but time consuming because of the small adjustments you have to make on the front and back end to get the rail to sit flush. I noticed what people were saying about the gaps as I had the same problem. It's all about adjusting the height on the rear and front end screws and playing with adding/removing washers. A flush type washer works great on the front. I ended up adding larger washers on the rear ends and flush washers on the front to help catch the rail into the correct position. Looks great!

I brought these to add to my blackout project I am doing on my WK2. They are a direct fit and very easy to install. They really add to the blackout look.

They the rails were a bit nicked up out the box- mildly disappointed with that. It happens in transit. Nothing that you can see with out really looking for it. Overall happy with the purchase and upgrade!

Dopest dope I ever smoked

I have an Altitude. I did not like the fake rails it came with. I ordered these. Everything wrt JustForJeeps was excellent. The only issue I had was with figuring out the installation of these rails. The end cap bolts require adjustments in order to slide the rails into place. I could not get them adjusted perfectly so the rails on the ends sit flush with the roof. The ends are sitting just off the roof about 1/8 to 1/4 inch. Anchoring the rails to the roof posed no issue. Those bolts just tighten right down with an Allen wrench. Just looking at the rails, they look great. They are secure to the roof as well. No one prolly notices the tiny gaps on the end, but I see them every day.

They fit perfectly and an easy install. One drawback is that they do not come with the proper screws. There are four special screws that are needed for the front and back mounting.

Bought these as a replacement for the Black trim pieces that come on the Altitude and SRT models. I have a 2015 GC Altitude. There was no drilling required as the bolts were all aligned properly. The front and end slide in to place. I do not think the bolts that were existing are the proper pieces to use for the new rails but I made them work ( had to take out the washer). It does not require a lot of skill to install, just some patience as getting the front and back bolts aligned correctly and set correctly takes a few tries. I recommend putting masking tape on your roof to avoid scratching as the rails slide into place.
