I like the product. It is exactly what I need. No alternatives are available for the front end of my 2024 GMC Sierra. However, my Denali trim package includes a bunch of ride sensors that are mounted around the area where I need to install. what looked like a simple install in the Timbren video is much more complicated. I have not taken the "plunge" yet.So, I am hesitant to recommend this for a Sierra Denali (and I suspect a Silverado High Country).but I would feel good about recommending this for any other trim package.

Reduced body roll and improved stability in the front. I feel the road a little bit more now but it’s a small price to pay for the improvements!

These are easy to install, the nuts are painted, place in a vice and thread the bolts through with a little lube before you attempt to install. The passenger side locator pin was slightly off, just took a hair off it with a grinder. All said it took 20 minutes to install. No need to remove wheels. This was installed on my 2019 chevy trailboss 1500, I use a boss htx v plow and this helps keep the front from bottoming out , also alot less body roll without the plow on. 4 stars because direction a generic and I had to just grab the bracket and figure out where it goes..also with a 250 dollar bolt on I shouldn't need to clean paint off the threads and use a grinder to fit. Check my pictures to see where it goes, couldn't find a single picture of this installed online.

Product is great, works as needed. Some threads on the bolts wouldn't match up with the nut, better quality control needed to ensure they thread. Had to get the tap and die set out to get them installed.
