OK back to the gears... My truck is a 2010 ECSB 5.3 2WD. I drive in town and on the highway (no off road). I just want more zip in the trip. :-) I have the G80 now and my truck has less than 24,000 miles on it... Going from 3.42 to 4.10, should I also get a Detroit True Trac at the same time???

 

I went to 4.10's labor was about $1300. I have a 6 speed 4x4. Honestly I dont think the difference was that significant.
