Duramax L5P Engine Upgrades

One of the best places to start for your own 2020-2022 Duramax L5P build is with our selection of Duramax Engine Upgrades. These Duramax engine upgrades let you get more power, more torque, better throttle response, and all-around better performance for your tough GM 2500HD or GM 3500HD Duramax. One of the most cost-effective ways of adding a tremendous amount of horsepower and torque all is with a Duramax Tuner or Monitor. These devices change the OEM engine management software and increase boost pressure, adjust fueling, and give you tons of power all without the need for any "hard" performance parts of all. One of our favorite Duramax L5P tuning devices is the Edge Pulsar System, which bypasses your Duramax's notoriously difficult to tune ECM and lets you make big power and tie in any of Edge's excellent Insight monitoring devices.

If the price of tuning isn't up your alley, or if you're concerned about your Duramax's warranty, but you still want better a performance, then a Duramax cold air intake kit may be for you. These intake systems give your Duramax L5P vastly improved airflow than stock, which in turn, gives your Silverado or Sierra a bump in power and throttle response all in an easily-installed kit. One of our most popular Duramax cold air intake systems is the 2020-2021 GM Duramax L5P S&B Oiled Intake. S&B's intake kit features a high-quality construction and replaces your Duramax L5P's air filter, air box, and inlet tuning with more efficient components so that you get better airflow and improved performance.

The 2020-2022 Duramax L5P Silverados and Sierras may have a great look and and a ton of a capability, but they're only really at their best when they have some lift and bigger tires than stock.

Duramax L5P Lift Kits

One of the best ways to give your 2020-2022 Duramax L5P build one of the toughest looks around is by adding a bunch of lift and fitting on some extremely big tires. Our Duramax L5P Lift Kits add a whole bunch of ride height on both the front and rear of your GM 2500 or GM 3500, which gives it an awesome, towering look along with the ability to clear extremely big wheel and tire combinations. These lift kits are available at a bunch of different price points and levels of performance so that you can find the perfect lift kit option for your Duramax L5P build. One of our favorite GM 2500 & GM 3500 lift kits is the 2020-2022 Duramax Cognito 4" Standard Lift Kit. Cognito's 4" lift kit comes with everything you need to lift your HD Silverado or Sierra a full 4" in the front and 2" in the rear, which gives your truck a great look that is sure to turn some heads, especially once you add some big tires.

Duramax L5P Wheels & Tires

The 2020-2022 Duramax L5P's look at their very best when they have an aggressive set of wheels and tires, and the good news is that there's plenty of GM 2500 and GM 3500 wheels and tires to choose from so that you can find the perfect look for your ultra-tough Duramax build. We have a bunch of Duramax 17" wheels, Duramax 18" wheels, and Duramax 20" wheels so that you can find the exact set of wheels that your Duramax L5P needs to look and feel it needs. We carry a nice selection of both 35" tires and 37" tires that will give your Duramax L5P a great look, more ground clearance, and better traction both on and off-road. That being said, if you do want to a 35" or 37" tire, make sure your Duramax build has at least some amount of lift before you make an investment.
