Lil' bit smaller 37's these days. Although the stated revolutions per mile are virtually identical so figure that one out.

those of you with 37s and the appropriate gearing in your diffs, are you able to cruise at 60-70mph safely and still lane change or swerve or stop effectively?

I'm confident to travel at higher speeds down the road with 37s. Most important thing of confidence for me is having the sway bars ON. Braking is effected from of course from 33s or 35s, but not unsafe.

I run 5.29s and cruise 70 to 85 mph no problem, I can lock up the brakes also no problem on 37s, I also don't run the front sway, use castor correction plates.
You wrote that you have 529s.... I'm on the fence of 488 & 529. Will you please give me flat & locked converter rpm at 60 & 70 in Drive & OD.

Thanks

Gearing has nothing to do with lateral stability while turning or making evasive maneuvers. I run both sway bars, and I am very comfortable with my ability to control the truck while making such maneuvers. I am running 37s over 4.88s and my speedo is within 1 or 2 mph of true speed between 50 and 75 mph. I frequently wheel with a whole fleet of 80s on 37s. Some have no sway bars, some have one, some have both. We have all learned to tailor our driving styles to the ability of the rig. The taller it is, the more you need to drive it like a big truck. Because it is.

Because in theory, at least on paper, 37's should be matched with a 4.81 gear ratio. The closest one is, of course, 4.88. You are very slightly over with 4.88 whig not a bad thing at all.
This will keep the engine and tranny with the designed spec by Toyota, in terms of efficient engine power band, fuel economy, torque converter lock up.

4.88 with 37's compared to stock gearing looks good on paper. Factor in the added unsprung weight of larger wheels and tires, and you'll appreciate going with 5.29 more. RPMS at highway speed with 5.29, is not bad at all.

I originally bought the rig with 488s over 315s. I think that is pretty close to 37s over 5.29. IF I was starting from scratch, I might have gone with the 5.29s as I want to be able to pull a trailer occasionally, but it is not enough difference to make the change now. John
