2020 - 2026 Chevy/GMC 6.6L L5P Duramax

2020 to 2026 CHEVY AND GMC 6.6L L5P DURAMAX PARTS AND PERFORMANCE UPGRADES

The 2020 - 2026 Chevy / GMC 6.6L L5P Duramax trucks have seen significant updates, particularly with the bold redesign of the Chevrolet models. However, while the aesthetics might have divided opinions, what’s truly exciting is the serious upgrades under the hood. GM has made remarkable improvements in the powertrain department, setting the L5P Duramax apart from its predecessors.

One of the standout features is the transition from the reliable Allison 6-speed automatic transmission to a new 10-speed automatic. The increased number of gears allows for smoother transitions, making towing and hauling much easier while optimizing performance. Whether you're towing a heavy load or cruising, the 2024 Chevy Duramax and 2024 GMC Duramax have the tools to handle it with precision.

L5P DURAMAX ENGINE AND POWERTRAIN OVERVIEW

The L5P Duramax engine remains powerful with its 445 horsepower and 910 lb-ft of torque, but the real upgrade is in the towing capacity, which has jumped to a staggering 35,500 pounds. The improvements in cooling systems, including a larger oil cooler and a new, more efficient fan, ensure that even when towing at capacity, your 6.6 Duramax will maintain optimal operating temperatures.

TOWING CAPACITY, COOLING IMPROVEMENTS, AND TRANSMISSION UPDATES

For those in colder climates, GM has made a smart move by integrating a larger block heater, along with a more convenient bumper placement for the heater cord. Additionally, the 2024+ L5P Duramax features a built-in cool-down timer that prevents the engine from overheating after heavy use, automatically cooling the engine when needed.

KEY PERFORMANCE UPGRADES FOR 2020 - 2026 6.6 DURAMAX TRUCKS

Upgrading your 2020 - 2026 L5P Duramax opens up a world of possibilities for enhanced power and efficiency. Consider these top upgrades:

• Fuel Injector Upgrades for L5P Duramax:

  With time, fuel injectors in the Chevy Duramax or GMC Duramax can lose efficiency. Upgrading to high-performance injectors restores power and ensures optimal fuel delivery.

  A high-flow exhaust system reduces backpressure and allows your 6.6 Duramax to produce more power while maintaining lower EGTs (Exhaust Gas Temperatures).

• Cold Air Intake Systems for L5P Duramax:

  Installing a cold air intake system ensures your L5P Duramax pulls in cooler, denser air for improved combustion and overall power gains.

• Performance Tuners and Chips:

  Fine-tuning your truck with a performance chip lets you unlock more power from your L5P Duramax, whether for everyday driving or heavy towing.
