2025 Ram ProMaster 2500 Service and Repair Manual

Sitting in the middle of the range, the 2025 Ram ProMaster 2500 adds payload capacity and longer body options over the 1500 while keeping the same 3.6L DOHC Pentastar V6, flex-fuel capable, and nine-speed automatic driving the front wheels. Tradesman, SLT and SLT+ trims cover everything from bare work vans to better-equipped crew and delivery builds.
