That’s what I did. My first Ranger had a 7.5” with 3.73 open. I went to 8.8” with 3.73 limited slip. I ran 30” tires.
My 92 has 3.73 gears with 30” tires. My green Ranger I swapped to 3.73 gears. Not exactly sure what tire size it’s going to settle on but I’m looking at 28-29”.
Choptop has 4.10 and I’m debating 4.56, it needs it with the bigger tires. I’m also debating 4.10 in my 88 which currently has 3.73 because I’d like to run 31” tires on it and it will likely be happier with the deeper gears. Even with the 5.0 in the green Ranger it’s not real happy with 3.73 gears and 31” tires, but that’s what I had so that’s what’s on it.
My F-150 has 3.55 gears and 31” tires and it works well like that. I’m inclined to go 4.10 and 37-44” tires on the rebuild though because that’s the direction I want to take the truck. It’s done well in its current configuration but the way I use it, I’d like to take a step up. I know a lot more now than when I originally put it together and I’d like to use that knowledge. Plus 31” tires aren’t exactly cheap anymore so there’s no real incentive to want to stick with those and I want 1-ton axles on the rebuild.
So long way around of saying to match gears and tire size. There’s a chart in the tech archives that works for RBVs. Full size stuff seems to react differently a bit because ever RBV I’ve owned was a dog with 3.55 or 3.08 around here but my F-150 is perfectly happy. Of course it does have the 300, lol. One of the most IDGAF motors ever made.
