2012 Tahoe is riding sweet again. These are awesome. Easy to install. Perfect fit. A++++
2012 Tahoe. GREAT all-in-one strut. So happy with these. Easy to install. Seems like good quality. Nice ride. A little stiff up front but that's to be expected with brand new springs. That stiffness will go away with some miles on them. I just ordered another set for my other Tahoe. Don't buy the cheapy generic brands. I tried those first and they were terrible. Monroes are amazing. Get you some.

Great value and easy DIY install.
Great products from Monroe. I had to replace the non magnetic ride front struts on my 2015 GMC Yukon and decided to try these. Also got the Monroe rear gas shocks as part of the kit. They arrived compressed and were easy to install with just basic tools (Floor jack and stands, sockets and torque wrench). The ride height is noticeably higher (maybe and inch or two) but in a good way. They ride so much better than the worn out originals. I replaced the sway bar rubber bushing as well to complete the install and it rides and handles like new. Would definitely recommend especially when all parts for the front and rear suspension were under $300 total. Local garage wanted $1500 to do the job. Took me about 2 hrs to complete the front and rear install.

Ride Quality Refresh
Easy driveway install on 2wd 2012 Tahoe. Took about 1.5 hours. Ride improved significantly. One package had been opened and had 2 nut’s missing, but wasnt a big issue given previous hardware was still available for mounting the lower portion of the struts.

Great OE replacement
Fits as described. The truck has 350k miles on it and these make the truck ride like new. Easy install and ride like a dream. Great quality as usual from Monroe.

Beware - bad batch of defective, poorly welded strut & coil spring assemblies
See pics attached. The first pic was the only one that appeared to be welded properly. The strut cartridge was not properly seated and welded to the mounting yoke on FOUR out of SIX of the products I purchased. I had to spend so much time and energy purchasing again and lugging these pretty heavy strut and coil spring assemblies back to UPS drop-off for return. There were MIG welding spatter BB's in-between the strut cartridge and the yoke, which prevented the strut cartridge from being seated against the yoke and resulted in anywhere from a 1/16" gap to a 1/8" gap on 4 out of 6 of these things. Only 1 of them was assembled and welded properly. The sixth one was almost as good as the first one, but still looked a bit rough, with a 1/32" gap, but thankfully no random weld spatter BB's in between the yoke and the strut cartridge. It was especially frustrating because you need to replace these in pairs. The 1st one I inspected was fine (first picture) The second one is in the 2nd pic. The third one is in the 3rd pic. I kept buying them, hoping to get a second one that was at least somewhat useable, so I could finally finish the repair. By the time I ordered the 6th one, I was exhausted from the whole ordeal. It took several weeks and hundreds of dollars to get this all sorted out. In the future I won't even bother buying any Monroe component for my vehicles. Too much hassle. Their Q.C. is non-existent and their fabricators just don't care to check what they're doing.

OMG why didn't I do this sooner! 2018 Tahoe LTZ/Premier magneride shock strut replacement
6 years ago, had a 2015 Suburban LTZ. Front magneride shocks went out. was $3,000 to replace at dealership. At the time, there were no other options for replacement. Fastforward, picked up a 2018 Tahoe Premier (LTZ) for a really good deal and the front Magneride shocks went out. Did research and now they have shock simulators by xineering that make the vehicle think you have magneride shocks, but you have traditional shocks. I saved $2,500 by converting the magneride to these shocks and they RIDE GREAT!!!! Like others mentioned, it did pick the front end up 2.5-3". I'm interested to see what it settles down too. Note1: I've never replaced shocks/struts before and they had videos online that helped a ton. Took about 1.5 hours with 2 people and the right equipment. Note2: You need to rotate the tops of the struts until you find the correct alignment with the top bolts to the holes. When it is lined up incorrectly it seems like it is just a little off and it might fit, don't do it, rotate it until it goes in the hole easy. Note3: We chose to loosen and tighten the top bolts through the hood and not remove the skirt from the fender well. Worked great. It was helpful with 2 people as 1 can be on top and the other can be in the fender well helping align tools and nuts to bolts Note4: After aligning the top, loosely thread a coupl of nuts to keep it from falling out, then align the bottom Note5: loosen the bolt holding the swaybar to the A arm/wishbone Note6: The bottom may take some manhandling to get in. A crowbar to push the wishbone down, a wrench to rotate the bottom of the shock, and thin screwdrivers for hole alignment were helpful.

Vehicle: 2010 Chevrolet Avalanche LT (without electronic suspension) Writing this review about three months after the installation, so I may update later but here are my thoughts. I was a bit worried since many people mentioned that their truck got lifted like crazy, rides were bumpy or their product did not fit. I must say that installation was super easy. One thing that surprised me is that this thing uses 18mm nuts, so if you don't have it yet, buy ratcheting wrench 18mm. You will save 1/2hr easily just with ratchet, due to small clearance. The car got lifted 1" right after installation. I thought it was because the front was sagging after 280,000km driven on original struds. But eventually after about 2weeks it settled down and is barely noticeable, maybe 1/4" higher, which makes sense to restore factory height. The ride is comfortable as before, it just feels little stiffer on smaller bumps. But I can tell you that big speedbumps are way more enjoyable because the whole front does not jump like before rather nicely roll over the speed bump. I also noticed better handling, especially when hitting the exit ramps at 60km/hr. It does not swing that much, so the improvement is noticeable. Overall I love them, and would recommend it as replacement for your truck.

I recently replaced the magnetic ride struts on my 2015 gmc yukon denali. I used these Monroe front strut assemblies and it is a night and day difference over the factory ride. Of course you have to delete the magnetic ride option but definitely worth the money spent. Shipping was fast and everything installed easily for a DIY job. Definitely recommend.

Product works perfectly once installed, however ordered two and one was not aligned perfectly, it was about half an inch off. Pain in the ass dealing with that. Almost sent it back but just fixed it ourselves. That definitely should not be an issue to deal with. Aside from that it tightened my Chevy up nice
