I've had numerous 3/4 and 1 ton Squares over the years and all of them had 4.10 gears with a 454. My current K30 has 3.73's with a 454. I think I figured about why the others had 4.10's was because they all had the Z82 factory tow package. The person that ordered this K30 for some reason didn't.

My R2500 Suburban (1989/454/TH400) came with the trailer tow package and has the 14bolt full floater setup with 3.73 gears. I'm generally not pulling 5000 pound trailers around so it works out fine.
