GM # 12499978 Roof Rack Cross Rail Package - Black Rails with Chrome End Cap

Took about an hour to install, mostly because I did it alone and had to keep walking around the car to tighten bolts and such. An extra hand would definitely speed things up. I found a couple of Youtube videos that showed how it installs. I recommend watching one of those videos just so you know what to expect. Overall it's a solid product and it all went together easily. Pay close attention to the instructions. You may think they are not detailed enough but there are. One bar is shorter than the other and the brackets are side specific. Each one is marked LH or RH for left-hand or right-hand. LH is drivers side and that is called out in the instructions.

Came complete and delivered in very short time. Good price and was very promptly delivered. Comes with Torx T25 head wrench.Fairly easy to mount once you figure out how to do it. Instructions do not indicate how to remove "rear end siderail covers". To do so, just grasp firmly at end closest to siderail and pull straight up. They are tight but will come off since since each is mounted on pressure clips that become visible once you remove the cover. Did not need to use anything to pry them. Although not a GM produced piece, there is a "you tube" video that provides "How to" mount directions which help to understand the not too clear instructions. Suggest you split hardware for each side and for each crossrail (front crossrail is the longer one) ahead of time since you have a left and right side for each crossrail . There are 8 "tap plates" ( two for each of the four sliders) . They are inserted on slider's slots (see instruction's step 2); two of the slots are somewhat narrow and you may have to tap plate into slot . Make sure the hole on the plate is aligned with slider holes so at time of mounting crossrail's support ends to slider with screw, it "catches" and can be tightened. Same for thumb wheel (used for tightening when placing crossrails in desired position once they are mounted) Note that one end of each crossrail is adjustable so the cross rail can reach across width in question and that there is no need to tighten the screws mounting the adjustable ends.

The product was a genuine GM product and fit our 2012 Buick Enclave very well. I have seen the reviews that suggest that the directions are hard to follow, but I didn't have any problems. I gave it 4 stars instead of 5 because the bolts that I received were extremely difficult to work with. The bolts have a 6 star opening (as opposed to a phillips type opening). Some of the bolts had a tiny prong in the middle of that opening and the tool they provided to crank the bolts didn't fit. I had to drill them out and use a different tool. Once the unit was on the car, it worked great.

After purchasing my Enclave, I knew that it needed roof racks for my ski racks and tote. Driving away from the dealership I saw another Enclave with an after-market roof rack - completely destroyed the smooth styling of the vehicle. These rails look great. Easy to install, although as other reviewers have noted, the instructions are not entirely correct: 8 screws not 4, "thumb wheel" in the list of contents is called a "tie down" in the assembly instructions. I checked the parts and assembly on the counter before installing on the vehicle, so I had figured out the shortcomings in the instructions before I started climbing around the vehicle.

I ordered this for my 2012 Buick Enclave and. It fits like a glove as an OEM product should and blends and looks great on the car. The directions are a little wanky but I eventually figured it out. What should quite literally be a 5 minute install will probably take you 30 minutes because of that. But once you figure it out, it's not hard. Well worth the purchase vs. getting it at a dealer.

Installed on a Buick Enclave with little trouble. I viewed 4 YouTube videos before installing. None was completely accurate, but I got enough information to do it correctly. Every video referred to the 8 screws as large or small. Those screws will only work where intended. The difference is that 4 of them are a security type that requires a special included wrench and a regular torx wrench will not work. Do not lose it! The hardest part is removing the rear end caps on the cars rails. Worked well with my cargo carrier.

Great item. Made it easier for six to drive to Florida for a week and drive back to Illinois. A must is to watch the u Tube video on installation. The instructions supplied need to be revised. If you have access to a ratchet, socket and a security torx bit like I used it speeds up the install process over using the supplied wrench. Some have stated an issue with wind noise, I haven't encountered this. You must have the two rails at least 14 inches apart, if closer, you may experience wind noise.

These are factory cross rails and fit perfectly! They match the car and I love the chrome with black look. Like others have stated watch the YouTube video for installation as the instructions are poorly written. I used these to put my Thule container on top of my 2015 Enclave and it worked great!
