Just like the title says
Just looking for personal opinions here
Didn’t feel like searching anything.
Blew my rear diff I want to go 4:88s but 5:29s are inviting.
I just don’t know if I’d like it with 5:29s as a dd.

If it's a DD I would go with 4.88, and if you still want further reduction after that maybe think about a different t-case

I'd say it all depends on how big of tires you have, how much time you spend on the freeway, if you care about your mileage, etc...

4.88 seems like the best compromise for my truck, since the 4.30 just isn't great with 33s and all the weight I added. I'd only consider 5.29s if I was running 35s, because if I did it with 33s I'd be cruising at nearly 3k rpm on my commute.

Tire size is an important factor here.
I am leaning heavily towards 5.29. 4.88 is such a small difference over 4.30. Remember your new tire/wheel package also weighs more, so a ratio calculator is not the whole story

Tire size and transmission?

I dd mine on 35's with 5.29 and it's perfect. Can still do highway speeds, yet I can just roll on the throttle to get up less steep hills. It's nice to not have the trans shifting all the time.

Running 35's, I am very glad I went 5.29. At 80mph I'm around 3,000rpm and it's still plenty happy. I don't do 80 often so I usually cruise around 70 and the RPMs are mid 2,000's. Great for city driving and very helpful in the hills.

Wheels soooooo much better with the 5.29's, way more control.

Info on the size of tires your running and /or 5spd/automatic transmission to determine what gear ratio you want to run. I ran 33’s with the stock 4.30 gears in my 98 limited automatic trans with the 3.4. If I stayed with those size tires I would of regeared to the 4.88s. I now have a straight axle in the front and running 5.29s on 37s.

Tire size AND transmission type (manual vs auto) are the 2 important factors.
With an auto trans you need to go one step lower (numerically higher).

For example, a 4 cylinder 22R with a 5 spd comes with 4.10 ratio.
Same engine with an auto comes with 4.30 ratio.

I’m an auto on 33s and want to go 35s but won’t happen anytime soon.
I feel like I have 4:10s not 4:30s for some reason
00 limited factory e-locker
I do all my driving on the hwy
My work commute is only 15min not a big deal
I have driven a truck on 4:88s and 35s and drivability was great even for a 3.0 felt like it had plenty of power until the steep grades.
I want to go 5:29 because I know the trail benefits but I don’t want to hate my truck until I get the 35s
I have a heavy foot and cruise at 80mph on the way to the trails

If you have a factory e-locker then you have 4.30 gears.

All of my calculations and plans are based on tire size, first gear trans ratio, and rear gear ratio.

The 4ECT automatic transmission has a 2.804 first gear. The 5-speed manual transmission has a 3.830 first gear.

Here are my opinions and some basic math,:

4.10 or 4.30 and 31.5 in tires are optimal with either transmission, the bigger tire you go, the more the lower first gear ratio on the 5-speed becomes attractive, IMO.

4.88 and 33-inch tires (this is my next step)

5.29 and 35 inch tires

The other factor you need to take into consideration is the rim diameter v overall tire height, meaning sidewall profile/ratio.

The smallest rim with the tallest tire will give you the most advantage off-road allowing you to air down and get the most sidewall flex. If you do a majority of highway driving however, a larger rim minimizes the sidewall flex and creates a more stable ride with less unsprung weight.

Make your choices based on your purpose, and math.

Aight ima thread jack this real quick.. I’m ready to go 5.29 but what’s the consensus on gear installation? Just buy the ring and pinion by itself, 3rd members ready for drop in? What’s the best route? And where are y’all getting them?

Ima go through East coast gear supply.
Everyone local wants an arm and a leg

This really got me thinking because my brother in law bought a factory elocker runner for his son and when he was getting ready to sell it
He swapped the rear end into his sr5 base model
He’s been running it like that for about 4 years now with no issues.
Either the small difference from 4.10 front to his now 4.30 rear is ok
Or it’s just a ticking time bomb

Small difference, and people don't drive in 4WD often, nor on pavement, so it's unlikely he'd notice on loose ground.

Also, I've seen e-lockers with 4.10 gears on the used market. Easiest thing to do is time the wheel to drive shaft rotations, or count the ring and pinion teeth (requires disassembly)

Apparently 4.88s are on BO
So I went with 5.29s
I guess I’ll just have more of an excuse to get the 35s on sooner rather than later.
