ReadyLIFT Suspension Inc. is excited to offer new 2011-2019 Chevy and GMC 2500HD and 3500HD truck owners a lift solution that won't break the bank nor permanently modify your truck. This is a true bolt-on Lift kit! The 69-3411 SST Lift Kit by ReadyLIFT will lift the front of your new HD truck a maximum of 3.5 inches! This awesome SST Lift Kit for GMC/Chevy HD trucks includes a pair of tough, heavy-duty tubular steel Upper Control Arms engineered to match the strength of your truck. 2011-2019 HD-specific lift-oriented ReadyLIFT forged torsion keys provide an adjustable lift while maintaining the factory ride. These super strong forged torsion keys are stronger than stock with the same design and features an indexing that is unique to this kit! The 69-3411 Lift Kit also includes CNC-machined differential drop spacers which lowers the differential and puts the front CV axles into safe factory angle on 4WD trucks. 2WD trucks will not use the diff spacers. To lift the rear of your new GMC Sierra Denali or Silverado 2500 HD truck, the ReadyLIFT SST Lift Kit includes OEM style 1.0" cast iron rear lift blocks complete with new U-bolts and hardware. A Tow Package version of this kit is also available with a taller 2.0" rear lift block - use 69-3412. Also included with this kit are new super strong tie-rod end assemblies to replace the weak factory versions. For the longest time, GM tie rod assemblies have been a weak link on all GM trucks. These heavy-duty steering assemblies install easily and incredibly stronger than the OEM units. You won't find this kind of attention to detail with any other lift kit for the new GM HD trucks! This great combination gives the new GM HD trucks a great raised stance using super strong components and allows for up to a 34" tall tire. NOTE: Requires the use of longer front shocks. Shocks not included with 69-3411. Recommend ReadyLIFT SST3000 Performance Front Shocks designed specifically for this lift kit. NOTE: Optional ReadyLIFT SST3000 Performance Rear Shocks 93-3411R also available - sold separately. NOTE: Single Rear Wheel Only. NOTE: Not for use on trucks equipped with factory TOP overload spring commonly referred to as a camper package. NOTE: 2011-2019 GM HD trucks require the use of ReadyLIFT 66-7822B Heavy Duty Torsion Key Unloading Tool.

 
  
 
  
 
 


 


TIRE FITMENT

34" Maximum tire diameter

34x11.50 for no rub on a 9" wide wheel with +12 offset

18" - 295/70R18

20" - 275/65R20

22" - 285/55R22

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.

Amazing for heavy monitors
Color: White, Size: without USB
I had tried other monitor stands that claimed they were heavy duty, but this is the first one that stood up for my curved monitor. I did have to re-order as it was originally missing the hardware, but once I received it it was easy to set up. The quality is great and it moves very smoothly for day-to-day adjustments.

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.
