2017-2019 Duramax Engine Upgrades

The L5P Duramax under the hood of your 2017-2019 GM 2500 or GM 3500 may throw down an impressive amount of horsepower and torque right off the showroom floor, but there's plenty of more power and torque just waiting to be unlocked by the right performance modifications. Our selection of Duramax L5P engine upgrades can add a ton of horsepower, torque, and response to your awesome Silverado or Sierra build. If you're looking to give your Duramax L5P absolutely huge levels of power and torque all in one place, then you'll want to grab a 2017-2019 Duramax L5P Tuner and Monitor. These devices change your Duramax L5P's engine management software, which increases boost pressure, changes fueling, adjusts shifting, to completely change how your 2500 and 3500 operates on the street, track, or trail. One of our most popular Duramax L5P tuners is the Edge Pulsar Tuner that bypasses the troublesome OEM ECM and allows you to use any of Edge's Insight monitors to get a complete tuning solution for your Duramax.

While tuning can get your Duramax a ton of power, they are extremely pricey, and they may not be the best solution for anyone worried about their factory warranty. If you still want power without a bunch of hassles, then check out our Duramax L5P Cold Air Intake Kits. An aftermarket Duramax cold air intake gives your truck a larger volume of charge air at a cooler temperature and higher velocity so that your GM 2500 or GM 3500 gets a bump in horsepower, torque, and throttle response all in one place. These Duramax L5P intakes are all extremely easy to install, making them a hassle-free upgrade for your tough Duramax build. One of our most popular Duramax L5P intake systems is the Duramax 6.6L Banks Ram-Air Intake System. The Banks Ram-Air Intake is a complete replacement for the factory intake and includes a new filter, air box assembly, and inlet tubing that all works together to improve airflow into your Duramax L5P in a big way.

2017-2019 GM Duramax L5P Leveling Kits

While the Duramax L5P Sierras and Silverados are certainly capable trucks from the factory, but like most trucks, they come with a stinkbug-style rake and can't exactly clear the biggest tires at the factory ride heights. The good news is that we here at Alligator Performance have more than a few Duramax L5P Leveling Kits that can get your tough GM 2500 or GM 3500 just enough front ride height to get a clean, leveled look and the clearance to mount up bigger wheel and tire combinations. These Duramax Leveling Kits range from basic torsion key systems that give you ride height while saving you some cash to complete suspension systems that come with high-performance shocks that give your Duramax build huge handling performance both on and off-road. One of our favorite GM Duramax leveling kits is the 2011-2019 GM 2500 & 3500 Cognito 3" Performance Leveling Kit. The Cognito 3" Performance system includes torsion keys, high-quality control arms, and complete set of Fox 2.0 Performance shocks that give your Duramax excellent on-road handling and awesome off-road performance all in one kit. The 3" of extra front ride height also lets you clear some seriously big tires without a bunch of hassles.

2017-2019 GM Duramax L5P Lift Kits

If a leveling kit just isn't enough ride height for your or your choice of tires, or if you just want a big, bad look, then a complete Duramax L5P Lift Kit may be right up your alley. These GM 2500 and GM 3500 lift kits come with everything you need to get your tough Sierra or Silverado up high in the air and clearing absolutely huge wheel and tire combinations. We have lift kits to fit just about any budget at a variety of different lift heights so that you can find the Duramax lift kit that's perfect for practically any Duramax build.

2017-2019 GM Duramax Wheels & Tires
