Chevrolet 3.0 Duramax 2025. Looking over the numbers, we see that the maximum weight a 2025 silverado can tow is 13,300 pounds with a ball hitch and the 3.0l i6 lz0 engine. 95 percent of peak torque happened at 1,250 rpm.
Hey everyone, i did search the forum and read over all the existing towing threads and so far it is sounding like the 3.0 duramax is going to fit the bill. The 2025 chevy silverado zr2โs duramax diesel engine has proven efficient, but we werenโt ready for its astonishing best tank of 34 mpg with 826 miles of range!
