Light Bars

Popularity 5%

Fog Lights

And to be ready for any condition - install fog lights on your car - they will help you to maintain visibility during even the darkest weather - and then not a single pothole and not a single obstacle will be a surprise to you.

The horsepower of the 2011 GMC Sierra 3500HD is an important factor to consider. The horsepower is a major selling point because it’s a good way to measure the 2011 GMC Sierra 3500HD engine’s ability to do work.

A higher horsepower rating usually means that the vehicle will be able to accelerate faster and tow more weight. However, there are other factors to consider besides horsepower when choosing a vehicle.

But even if your car does not have outstanding performance - do not despair. You can make your car significantly more powerful with even minor modifications!

Performance Tuners +20-40 HP

The easiest thing to do is to change the engine power programmatically. Use tuners for firmware injection - and program the car the way you feel comfortable!

Or you can use a Throttle Response Controller like Pedal Controller. It does not increase your engine's horsepower, but allows your engine to respond faster. This device eliminates the delay from your electronic gas pedal, allowing your GMC Sierra 3500HD to accelerate faster.

Cold Air Intake +10-15 HP

Install simple upgrades such as cold-air Intake. They are cheap, easy to install, and give a nice power bonus to your GMC Sierra 3500HD that you'll feel as soon as you install and start the engine. As their name suggests, cold air intakes bring cooler air into your engine and combustion chamber. In doing so, cold air intakes boost engine power and efficiency. That's because colder air has a higher oxygen density.

Turbocharger +70-150 HP

One of the most popular ways to add horsepower is to install a turbocharger. For all engines, the turbocharger will increase power by about 30 - 40 percent. If you have changed an injection system, the efficiency can be up to 100 percent or more. The main benefits: Improved torque, more power, fuel economy, better acceleration at the low RPM, brings big tuning potential.

Cons: Increased complexity, requires fine-tuning, price.

Exhaust +2-5%

More specifically, large engines like a big 6.0L V8 typically see about a 2%-3% horsepower increase. Smaller engines, like a 1.8L 4-cylinder, typically see a 3-5% horsepower increase.

But if you want your car to not only deliver awesome power, but also sound like it has the heart of a beast - think about tuning the exhaust modifications! You'll get a nice-sounding engine roar, and as a bonus - a small increase in horsepower!


However, sometimes you don't even need to apply such serious updates - sometimes to make the car more powerful, it's enough just to replace consumables. Replace the spark plugs, install a new catalytic converter if the old one is out of order - and you will feel that your car will produce power as if your GMC Sierra 3500HD left the showroom yesterday.

There are more than a dozen factors that affect the performance of your engine, but perhaps the most important ones are quality gasoline and clean, cold air. And while it's more complicated with gasoline quality, because you can't be sure your tank is filled with high-quality fuel, it's your responsibility to make sure your engine's combustion chambers are filled with clean, cold air.

Why did I say cold air? To keep your engine running smoothly, the air needs to be cool to promote complete combustion and, as a result, to increase horsepower. Install an intercooler in your car - this system is designed to take all the air that goes through the intake system, and it will go into the combustion chambers already cooled - at a temperature that's optimal for the engine's operation.


Cold Air Intakes

Popularity 32%

Operating at high temperatures negatively affects engine performance - this is one of the most significant reasons for power loss and increased fuel consumption. One of the major causes of engine overheating is the hot air that enters the combustion chamber. To eliminate this problem and bring the engine temperature back to normal - install a cold air intake - with this improvement, cooled air will flow into the cylinders - which will have a positive effect on power and reduce fuel consumption.

Throttle Body Spacers

Popularity 27%

You may not realize it, but your car is held back by a number of restrictions that are easy to remove. One of these is the throttle body spacer. A throttle body spacer is an easy way to improve your car's performance and fuel economy. By reducing the amount of air that needs to be squeezed through the engine, a throttle body spacer allows your engine to breathe easier, resulting in improved acceleration, reduced turbo lag, and increased fuel economy.

Exterior Upgrades

Fender Flares

Popularity 22%

Installing fender flares is a great way to improve the look and performance of your car. Not only do they add style, but they also help protect your car from mud and debris buildup. Fender flares are available in a variety of styles, so you're sure to find the perfect set for your vehicle.

Bike Racks

Popularity 17%

And as luck would have it, your bike was left at home, thousands of miles away, because it absolutely did not fit in the trunk of the car. I'll be honest with you, I've been in this situation a lot.

Center Consoles

Install the center console in your car - and you'll get such an important place to put everything you need - and it will not bother either you or your passengers.
