Does anyone think 4.56s would be to much gear for a 08 Silverado with 4L60E

Forgot to mention truck will soon have 33/12/17 tires and 3.5 rc lift

Ok boys, 5 months later and I'm calling the shop Monday for an installation appointment. I've got all my parts needed including both 3.73 & 4.11gear sets, front& back. Any last words of persuasion for either gear? I'm planning 4.11, hope I don't regret the decision but I'm thinking all of that will wash away the first time I leave a stop light with the new gears!

well i got a crew cab with 3.73 and 265/70/17 (31.7")and it seems pretty peppy. im spinning around 2k at 70 and i kinda like the balance between them. these tires were on the truck when i got it but when it gets time to get new ones i plan on getting some that are a tad smaller in diameter (~30.5") so it would lean more towards the 4.11.

edit i would mainly lean to the 4.11 if i had a choice as ls engines love their rpms. the 200rpm deference shouldn't be that bad but would help lugging the heavy truck around better.
