So I was pulling a 8x16 enclosed trailer and first off the truck really didn't seem to like that haha but this got me thinking. I have 33s on my truck now and it seems to now be searching for gear. The truck would kick down back to 3rd with the slightest head wind. I feel like if I had a few more RPMs in the truck it would be much better. I have 3.73s now and what I want to know, hopefully guys that have regeared can chime in, is a 4.10 gear worth the effort? I feel like it would give me the smallest bump in RPMs and keep me more in the power when trying to do 55-60 with a large trailer. I feel like a 4.56 would be too big of a jump but if I'm wrong let me know! I think I see a 4.30 gear for the 9.75 rear end so I wonder if I could get one in the 8.8 as well?
