The 2024 L9 engines do more than just provide the power, reliability and durability you need to get the toughest jobs done. The 2024 L9 delivers class-leading power and torque ratings, an unmatched power-to-weight ratio, and the dependability and uptime you expect from Cummins. With ratings ranges of 260 hp to 380 hp (194 – 283 kW) and up to 1250 lbft (1695 N•m) of peak torque, the L9 is designed to excel in some of the toughest duty cycles. High-strength components and features, like replaceable cylinder liners for easier rebuilding, add life to the engine and add to its residual value.All About Uptime:With extended recommended engine maintenance intervals, you can go longer between oil drains and fuel filter changes. A completely maintenance-free breather means you’ll never have to change a crankcase ventilation filter again. Trucks go longer between trips to the garage for scheduled maintenance, and more money goes back to your bottom line. Also on the 2024, the L9 offers advancements in connectivity to help you find, prevent and resolve issues faster.Know more.
