The lift kit utilizes the very best in ReadyLIFT engineering with boxed steel front/rear cross members and a full-width front skid plate constructed of thick 3/16-Inch plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting.Our 6 Inch (6 Inch + 2 Inch) lift kit features heavy-duty angled and offset top mount strut extensions that realign the struts to optimize shock performance and minimize wear.

A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle the larger wheels and tires that will find their way onto this new lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings have been added as well as new rear Falcon 1.1 Monotube shocks.With months of engineering and development and more awesome features than we could possibly mention, this new Big Lift Kit is the best 6-Inch lift kit you can install on a new body style 2025 GM 1500 4WD truck built with 2-Inch factory lift!

Thousands of miles of road and trail testing have proven our new 6-Inch lift kit makes these new GM 1500 trucks ride better than stock!

BUYER BEWARE!! ITS GARBAGE YOU WOULD BE BETTER BUYING A $20 MONITOR MOUNT INSTEAD
Color: Black, Size: without USB, Color: Black, Size: without USB
This is the second review I ever gave on Amazon out of thousands of items I bought over the years.. This is the worst monitor mount I ever bought I have purchased maybe ten over a long period of time this monitor mount isn't the cheapest so you would think your getting quality your not it's garbage worse than garbage because it can break your monitor mine decided to give out and slam down thankfully it didn't break my $1100 oled monitor also it has weird screws you have to screw in to get it to rotate 360 degrees it has a screw that clamps down on your desk and will leave a mark and damage it.. To lower it you have to turn it 500 times loosen it up and it never feels stable also the tilt feature is litterally the worst no matter how high you try to level your monitor it always hangs downwards I have a light monitor well within the weight capacity.. I would buy any other monitor mount so buyer beware if you want junk and waste your time fiddling and trying to get this in a good position you won't and it will just get you super aggravated I wish I could give this item zero stars

Worth the price an pretty good angles
Color: White, Size: without USB
So I decided to get this monitor arm because I was trying to go for an all white aesthetic and needed a arm to come in on time was a little skeptical because of the reviews but after using it, I love it. It’s super sturdy. The monitor arm is pretty high-quality. It uses mostly metal and the cable management is really good. I definitely recommend it.

Easy to use
Color: Black, Size: without USB
Easy to use and set up. The quality of the item seems to be there - sturdy enough to hold my 34” ultra wide Samsung monitor. Worth every cent with how easy it is to use and readjust the angle of the screen - I had to stiffen the resistance to account for the added weight of the monitor, but the fit and stability is spot on once the adjustment was made; just a few turns of the screw with the included Allen key
