How do ya'll think a Tahoe with 4:10s, 4WD, and the 4.8L and Auto Combo would do? It's a pretty high ratio, but it should help out the smaller motor. I'm worried about too high of RPM out of OD. How would the tranny hold up in Drive in Tow/Haul mode, pull a tandem trailer with a full-size jeep on it??? Does anyone else tow with a 4.8L and 4:10 combo???
i believe mine are 3.73s. Power has never been the problem, just the short wheelbase (mines regular cab short box). Its no cummins, but it does the job. Your 4.10s should make it pull better than mine, so you shouldnt have to worry.
4.8 tow i have towed way over the limt with my 06 4.8 5 speed RCSB it tows fine on the flats uphill is lacking had to drop it to 3rd , the revs are fine but what will hurt you is lack or real stiff rear springs and brakes , sorry for posting a old thread. pss gears are 353 and i hate them.
