Neighbor just got a set of 3.8 masher. But I'm afraid stock gearing is going to over heat his truck. What should he be running? He is using both 4s and 6s. Thanks

I'm running 20/54 with badlands.
I'm not krazy. My mother had me tested.
There are many factors, too many to give any good advice. The best advice here is to just get a temp gun, which can be had for <20$, and measure the temp now an then.
