Upgrade Your Truck with Performance Parts

While modifications like lift kits, aftermarket wheels, and oversized tires can significantly improve your truck’s aesthetics, they can also negatively impact performance. Added weight and rotational mass immediately affect factors like acceleration, fuel efficiency, and stopping distance, making driving your vehicle far less enjoyable. Luckily, RealTruck carries a wide inventory of performance truck parts to counteract these negative qualities, significantly improving driveability.

Gifts for the Performance Junkie

If the auto enthusiasts in your life have a need for speed, consider RealTruck’s selection of performance truck parts. We offer everything necessary to boost a vehicle's performance, ranging from simple drop-in upgrades like high-flow air filters to high-end mods like performance stainless-steel cat-back exhaust systems.  

For the sake of this guide, we’ll keep these modifications within the $300 price point.

Programmers & Monitors

You can't beat a tuner or programmer if you’re looking for a product with a simple installation yet dyno-proven performance results. These products modify particular parameters in an engine’s computer, like ignition timing and fuel pressure, boosting efficiency and, thus, power.

Tuners and programmers offer one of the quickest and most hassle-free installations, requiring only a simple plug into a vehicle's OBD2 port. 

Under $300, we recommend throttle-sensitivity boosters and simple plug-and-play modules, like the DiabloSport Sprint or Pedal Commander Throttle Response Controller. 

Drop-In Air Filters

While finding a high-end intake system for under $300 is tough, we offer several budget-minded air filter options that improve filtration, airflow, and service life. 

Products like the K&N OE Direct Fit Stock Replacement Air Filter and aFe OE Direct Fit Stock Replacement Air Filter feature heavy-duty urethane housings and high-flow filter media, just like the filters included in cold air intake systems. However, they drop directly into the factory airbox for a quick and easy installation.

Most high-end air filters are also washable and reusable, allowing you to clean and re-oil (if applicable) the filter at each service interval rather than disposing of it.

Types of Performance Parts

At RealTruck, we carry a wide variety of aftermarket truck parts for your ride, ranging from cold air intakes and exhausts to heavy-duty brake pads. Check out some of our most popular categories below.

Engine Performance Parts

Engine performance parts extract dyno-proven horsepower and torque gains from your truck’s powertrain. With more power, your truck will exhibit sporty driving characteristics, tow better, and even get better fuel mileage—so long as you can keep your foot off the throttle. Common products in this category include:

Cold Air Intakes

The most popular bolt-on performance mod, utilizing high-flow air filters, oversized air boxes, and smooth, extra-wide thermoplastic intake tubes for maximum airflow into the engine. As we all know, more airflow = more power.

Performance Exhaust Systems & Components

Just as essential as cold, clean airflow into an engine is exhaust flow out. Performance-centric exhaust systems utilize large-diameter mandrel-bent tubing and high-flow mufflers to funnel exhaust gasses out of your vehicle’s engine more efficiently, allowing more airflow into the engine and, thus, more power.

Performance Programmers & Monitors

Programmers and monitors are another popular category of performance products. These digital products require minimal labor for installation. Simply plug the programmer into your truck’s OBD2 port, follow the prompts on the display, and you’re ready to go. 

Performance programmers differ from monitors in that one modifies specific parameters of your vehicle’s drivetrain—like fuel injector pulse, fuel rail pressure, and ignition timing—to boost performance while the other only allows you to monitor these parameters. Programmers produce dyno-proven horsepower and torque gains and improve fuel efficiency, especially among diesel engines. 

As a bonus, programmers and monitors are easy to uninstall and restore to factory settings when it’s time to sell.

Brake Performance Parts

When you think of performance, you’re likely picturing modifications that improve acceleration and fuel efficiency, but what about braking? Your pickup’s brakes are one of the most vital systems—however, these components are often overlooked in discussions of performance. 

Break the cycle and boost your ride’s braking power with premium brake rotors, lines, and pads from RealTruck. Upgrading your ride’s brakes directly impacts stopping power, stopping distance, heat dissipation, and overall brake performance. In an emergency or sudden maneuver, adequately performing brakes can be the difference between avoiding or getting into an accident.
