5.13 or 5.38's

[Pete]

Found a guy on pirate that has awesome prices on Yukon stuff so I'm going to order from him, should I go 5.13 or 5.38's? Tires will be 37s

[HitItWithSomeSpeed]

I went with 5.38's planning on going to 37"s.

It was a tough call, but I was on the fence and I figured I'd rather be over geared than undergeared.

Cant tell you how they are tho, still sitting in a box in my garage

5.38's

I don't know of many people who complain about being overgeared in the axles. Now taking into consideration other variables(engine, trans, transfer case) might sway what gears i would go with.

For example. If i was building my Xj (4.0/aw4/231) For 35's if i was building mine I would go at least 4.88's but i would probably spring for 5.38's just because i like low gear... and it is less strain on the drive train. But if i had plans for 4:1 transfer case or a v8 i would go with Numerically lower gears.

My friend at school has 35's on a 4.0/ax15/231(4:1) and he absolutely hates it. WAYYYY too low of gears. He says he wants to re-gear to 4.10 it is so low. But i imagine that is because everything else has a lower gear.



In all of that talking i don't think i answered your question... just things to consider.

sam runs 5.38's on 35's with a 4.0 auto and loves it. i've been in it and it runs great even on the highway. just food for thought

i'm gonna be running 5.38's on 39's with a 3.8 tcase. i'll tell ya how it is in 2 years lol.

everything i have heard though between 5.13 and 5.38 is that it is such a minimal difference, that your just better off going alittle lower.

I went with 5.38's. Got a smoking deal, both gear sets, Yukons, both install kits, Yukons again, spool, Spartan locker with shipping for $1,100.

On the contrary... i heard that since there is such a minimal difference that it is better to go with 5:13 because of the slightly larger pinion... I would still go 5:38.

Im 5.13s on 35s, wish I was at 4.88s

I don't think you will feel much difference between 5.13s or 5.38s one way or another to be honest, so I wouldn't sweat it, you got a smokin deal.
