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.

Easy installation & perfect fit for my 2nd 2010 Suburban. Product was as described and I could tell a noticeable improvement in the overall ride quality immediately.

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.

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.

Installed in a 2016 Chevy Tahoe. They work as expected
