2001-2004 Duramax LB7 Engine Upgrades

While the Duramax LB7s had pretty impressive power outputs when they were first released, but they're OEM numbers have been overshadowed quite a bit by much newer Duramax models. That's the big reason why our selection of Duramax LB7 engine upgrades is usually one of the first stops for folks looking to get more out of their GM 2500 or GM 3500 build. These engine upgrades can get your Duramax more horsepower, improved torque, and better throttle response all in one place. Adding even the most basic engine upgrades for the Duramax LB7s can get your truck huge, new power levels that will have your Silverado or Sierra tearing up the street, sled pull, or trail in almost no time at all. One of the most effective ways to get your truck more power is with a Duramax LB7 tuner. These devices come with new software for your truck's ECM that changes key parameters of the OEM engine management system so that your Duramax LB7 churns out a ton more horsepower and torque. These tuners adjust boost pressure, fuel curves, and even transmission shift points and pressures so that your LB7 build feels like an entirely new truck. One of our favorite tuners is the Edge CTS3, which contains extremely powerful LB7 tunes that are paired with a device that has a huge color touchscreen display that makes it one of the most effective monitors on the market.

While tuning is a potent option for your Duramax LB7, tuning devices are pretty pricey, and you may not necessarily want to be running extra boost pressure and fueling through a motor pushing 20 years old. For folks that are looking for something more mild, take a look at our Duramax LB7 cold air intakes. These Duramax intake kits give your Silverado or Sierra a bump in horsepower and torque in a package that won't break your bank or give you hassles during installation or operation. These LB7 cold air intakes give your Duramax motor a larger volume of cooler charge air at higher velocities than the factory air box and paper filter, which adds horsepower, torque, and throttle response all in one place. One of our most popular intakes is the Duramax LB7 S&B Oiled Cold Air Intake Kit. S&B's intake features a highly-efficient design and high-quality construction in a kit with a great price point. S&B's intake comes with a new oiled air filter, complete air box assembly, and full inlet tubing that replaces the entire stock intake and gives your LB7 all the charge air it needs to make some power without a bunch of headaches.
