An aggressive sound is something that you want your Silverado to have. After all, you have spent all of this time trying to enhance the look and performance of your truck, why not make it sound the part too? At AmericanTrucks, we are proud to be able to provide you with throttle bodies & accessories to enhance your truck’s overall performance. These devices are made to ensure that you can get a maximum burn with superior efficiency at the same time. The moment you install a throttle body onto your truck, you will relieve the factory restrictions and experience a serious boost in horsepower and torque. Often times, the throttle body takes a back seat when you start to replace the performance parts, but it doesn’t need to as it can enhance and draw out the best in your truck. Many of the throttle bodies available on the market today are made from aircraft grade aluminum that is a 6061-T6 grade rating or some type of similar material. Each one of the throttle bodies are cut with precision in mind to ensure that the piece will fit on your truck and provide superior performance gains. The manufacturers understand how to make the throttle body work efficiently and they have worked hard to make sure that all air that passes into the combustion chamber is pure and rotates quickly to maximize the fuel to air ratio within. When you have a solid air to fuel ratio, you will experience more horsepower and torque output from the engine and boost those RPMs right before your eyes. AmericanTrucks offers some of the best throttle bodies that are manufactured by top name brands in the industry. You can choose a name brand that you are familiar with or you can choose one of the recommended brands by our team or other customers. While the throttle body is an important piece, you will find that throttle body accessories are just as important, and they can affect the way that your truck works too. Throttle body spacers are available in our shop and they work to provide you with a better burn efficiency. These spacers are designed to increase the overall turbulence of the air intake when the fuel is added to it. If a throttle body is not yet on your list to replace, you definitely want to consider the spacers, as they are affordable and will provide your engine with a rush of increased power. When looking at throttle body spacers, it is important to know that they are made to target your RPMs and send them into a range you did not even know your truck was capable of doing. AmericanTrucks carries some of the best 99-06 Silverado Throttle Bodies & Accessories and you can get your hands on them quickly and affordably too as we keep our prices as competitive as possible. If you are feeling a little experimental with your truck, we recommend that you try to put a new twist on things and try out one of the updated throttle bodies that are manufactured to make the air whirl as fast as possible when it enters the combustion chamber to ensure it mixes much more thoroughly with the fuel droplets to provide you with even hotter and better combustion for the engine. You will notice that your RPM gauge puts you in a new range and that you will not be stuck with that muted power any more. AmericanTrucks does offer you a complete lineup of throttle bodies and accessories to spice up your truck. Many of the parts are made from billet aluminum, which is known to hold up over years and will provide you with the durability you desire and need for your truck. Many of the top manufacturers also offer a complete warranty with their products, which will give you the peace of mind that you are after. Don’t waste another minute on the racetrack with a throttle body that cannot provide you with the performance that you need from it. AmericanTrucks has the products needed to upgrade your RPMs and put your truck into a class of its own. In most cases, you will be able to install these throttle bodies in just a couple of steps and most of them do not need to be tuned, but some of them may require a custom tune to enhance the performance that you do receive. Check out our current products and let us ship new Silverado throttle bodies & accessories to your door.
