Instant torque for towing and offroading, screaming top-end for the street
Unleash the true potential of your GM Truck with Magnuson’s TVS1900 Supercharger Kit. The industry's first supercharger kit for the 2014-2018 GM Sierra / Silverado 1500 L83 5.3L V8 (Direct Injection), this bolt on supercharger is designed to deliver maximum performance while retaining factory-like drivability and reliability. Generating 6 psi of boost, the Magnuson Supercharger delivers power gains of approximately 105 horsepower and 105 lb-ft of torque at the rear wheels, for a total of 416 hp and 444 lb-ft at the wheels! But peak horsepower and torque numbers don’t tell the whole story. "Under the curve" power is significantly enhanced delivering near instantaneous boost and torque upon demand that really pins you back in your seat. So whether you are roaring down the drag strip, towing a trailer, hauling a heavy load, or taking the family cross-country our TVS1900 supercharger will give you the torque and horsepower when you need it.
Industry-leading Intercooler Performance
Inside of the supercharger manifold, a large liquid-to-air intercooler keeps your Intake Air Temperatures in check and provides consistent and repeatable performance. Combine that with the front-mounted heat exchanger, electric water pump, and intercooler coolant reservoir and you have a supercharger system with IATs that are typically only 20-40 degrees (Fahrenheit) over the ambient temperature.
Bypass valve for fuel economy - horsepower without compromise
Maximizing your efficiency during cruising is the job of the supercharger’s integrated bypass valve. This vacuum operated system allows air to bypass the supercharger and the rotors to “free-spin" under light engine loads. During this situation the parasitic loss of the supercharger system is essentially negated taking less than one-third of a horsepower to turn the rotors. This bypass valve also allows your supercharged vehicle to maintain stock-like drivability and fuel economy - giving you a package that delivers power without compromise.
Down to the smallest part, our bolt-on supercharger systems are engineered as a complete package.
The supercharger, supercharger intake manifold, inlet, pulley, fuel injectors, fuel rails, front & rear fuel crossovers, and intercooler come pre-assembled to make installation simple and easy while the accessory box is organized into individual sub-assemblies to help ensure that you don’t lose track of parts in the middle of your install. All of the hardware needed for a full and complete install is also included so you won’t be running to the local parts store in the middle of your installation. In addition, our full color, step-by-step Installation Manuals will walk you through the install process with exacting attention to detail.
OEM level reliability
Magnuson’s TVS1900 supercharger utilizes EATON’s latest 6th Generation TVS rotor technology found in such industry leading performance vehicles as the Corvette ZR-1, the Cadillac CTS-V, and the Mustang GT500. The TVS Superchargers feature a pair of four-lobe, high-helix rotors with 160-degrees of overall twist that are housed in Magnuson’s patented high-flow housing. This highly efficient package requires less power to drive, delivers cooler discharge temperatures, and is much quieter than many of its competitors. These superchargers are all manufactured in our TS16949 certified facility – the highest ISO OEM quality certification standard in the market.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious.
To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.

Looks nice, easy to install
Color: Rustic Brown, Number Of Shelves: 2, Size: 22in
This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware.
I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.

Great center piece for my gaming room
Size: 7.9"D x 39.4"W x 34.3"H, Color: White, Size: 7.9"D x 39.4"W x 34.3"H, Color: White
It’s quite large, but you can display a lot of your cool collectibles on it. It arrives in a nicely packaged box with instructions, although I found the instructions to be quite basic. Most people should be able to figure it out.
Instead of following the instructions, I recommend forming the honeycomb structure on one side and then attaching it to your wall. Drill holes through the holes in the honeycomb, ensuring everything is level. Once the entire unit is assembled, one person can hang it on the wall. However, I suggest having a building partner. I attempted it alone and was straining my core while reaching on a ladder, which was probably not the wisest idea. The build quality appears to be very good, and I believe it will last for many years. The LED light colors are nice, though not as good as those on a razor, but they’re not bad for a third-party product. There are plenty of screws to install, with a couple of extra.
Just for reference my computer screen in the g9 57 inch that’s how big this shelf unit is. Holds up to 120 lbs
