Freightliner Performance Parts
Your Freightliner isn't just a truck—it's your business on wheels. Every mile logged, every load delivered, and every hour on the road represents your livelihood and reputation. Since 1942, Freightliner has built trucks that work as hard as you do, engineered for the long haul and designed to keep America moving.
But when your truck is your business, factory performance isn't always enough. You need more power for steep grades, better fuel efficiency to maximize profit margins, and the reliability to keep your rig running mile after mile. That's where performance upgrades make the difference between just getting by and dominating the road.
Breathe Easier, Haul Stronger
High-flow air filters deliver cleaner, cooler air to your diesel engine, improving combustion efficiency and throttle response. When you're hauling heavy loads up mountain passes or navigating city traffic, enhanced airflow means your Freightliner responds with the power you need, when you need it. Better air intake also helps your engine run cleaner and last longer—protecting your investment for the hundreds of thousands of miles ahead.
Exhaust Systems Built for the Working Class
Performance exhaust systems reduce backpressure and improve exhaust gas temperatures, helping your diesel engine breathe more efficiently. The result? Noticeable gains in horsepower and torque that translate to better acceleration, easier merging, and more confident passing. Plus, improved exhaust flow can contribute to better fuel economy—money saved on every tank means more profit in your pocket at the end of each run.
Unlock Hidden Power with Performance Tuning
Performance chip tunes recalibrate your Freightliner's ECU to optimize fuel delivery, boost pressure, and timing parameters. These precision tunes can unlock 50+ additional horsepower and significantly increased torque, giving you the muscle to conquer any grade while maintaining smooth, reliable operation. Whether you're running cross-country routes or local deliveries, a properly tuned engine works smarter, not harder.
