Put on an electric fan.
No electric fan can move as much air as the stock clutch fan on these trucks. That's why they use them.
As of 2021 all domestic 1/2 tons come with OEM e-fans. The much smaller fan to shroud clearance has a decent increase in efficiency, hence Ram gets away with 900 - 1000 watts instead of the 5 - 10 hp mechanical fan.
But in the OP's case, something is not right. Even a 10 hp parasitic draw shouldn't decrease speed from 50 to 40 mph, that's closer to a 50 hp draw.
Furthermore, the e-fans used on autos for the last 15-20 years typically outlast the radiators, hoses, etc.
I agree with RoyJ. Something's not right. If the fan clutch is kicking in often and you can't maintain speed, you have other problems.
