Mama always said, "If it ain't broke, don't fix it." Well, we're here to tell you that Mama was wrong. The Dodge Challenger is not broken — it's one of the most iconic muscle cars that's ever existed — but that doesn't mean it can't be fixed up. In fact, we carry a massive range of 2008-2021 Challenger engine parts that prove our point.
Whether you have the 6.4L Hemi, the 5.7L Hemi, or even the insane Challenger SRT Demon, there are always ways to improve horsepower, torque, and throttle response. That's why we offer everything and the kitchen sink to help you extract every ounce of potential out of your beloved beast.
Want throttle response that will pin you back in your seat? Check out throttle bodies with wider diameters than stock, or take a look at cold air intakes that deliver tons of fresh, oxygen-rich air to your engine to keep it performing like a champ. Our mass air flow meters and sensors are another great option — they monitor the air coming into your engine to help your system tweak your air/fuel ratio for max power and efficiency.
vNeed that extra boost to put you over the finish line before your rival? We've got supercharger and turbocharger kits that compress and force all incoming air into the combustion chamber to give you an almost unfair advantage. Almost. Our nitrous kits do the same thing, giving you a killer kick when you need it the most.
You can add individual parts and tweaks to churn out more horsepower, or you can buy a ready-made engine from AmericanMuscle. Crate engines and blocks give you pre-built power for a range of applications, whether it's drag racing, street performance, or track domination.
