With new stock 235/85/r16 tires and a getrag 5 speed in 5th you'll be at 2000 rpm.

4.10 is great for pulling heavy. It puts your shift points close together. Around town you will find it kinda busy and the slow shifting will bug you because you run out of rev's fast. 4.10 won't give you a lot of speed on the highway. I switched mine to 3.54 and have not regretted it. First gear becomes useful, specially when pulling a heavy trailer. The 3200 gov. spring helped make up for the wider gear spacing.
