Collection: 2020-2024 GM 6.6L L5P DURAMAX

The L5P Duramax engine continues to deliver impressive power with 445 horsepower and 910 foot-pounds of torque, but the 2020 model year brings significant towing capacity improvements, jumping from 23,100 pounds to a massive 35,500 pounds. This jump is facilitated by several upgrades aimed at maintaining cool operating temperatures, such as a larger cooling fan and oil cooler, and a relocated block heater for easier access. Additionally, an innovative cool down timer feature has been integrated to prevent overheating after intensive use. Overall, while maintaining the L5P engine designation, the 2020 models have undergone extensive changes, with the exterior roof being the only component unchanged from its predecessor, showcasing GM's commitment to innovation and addressing consumer needs.
