I have a 2005 z71 with stock 3.42 and 33's. All I ever tow is a 19' boat, and a pretty light camper, but it still doesn't like to shift into overdrive. Recently purchased cognito UCA's and 3" torsion keys, so I plan to put 35's on it, and I know it will definitely be awful towing then, so my question is, with just the torsion keys and 35's, do I need to go all the way up to 4.56, or will 4.11 be enough for what I need to do?  Also, what are some good posi lockers that would pair well with the new gears?
 
Go to at least 4.56's

My buddy runs 35's on his Tahoe with 4.56's and wishes he had gone to 4.88s!
