Gen 2 LS gear ratios, motor and other questions

[scrubber3]

94-96 would be the DOHC 3.0L in the LS. There's probably a unicorn, but most that I've seen in my search had the 4.875 axle ratio. Would make sense since the more powerful 3.5L DOHC got the 4.63.

The LS has a 3.0 SOHC which is the only option for the 2nd gen LS. The LS also has the same gears as the SR in nearly all cases. 4.62---.

I have an LS that I've done front and rear diff swaps with an SR. I've done much work to my rig. See my build thread.

You're right, the 24V 3.0L is still SOHC. I forgot about that.

It's not often a 24 valve V6 has only a SOHC per bank....

So to answer your question accurately, the highest percentage of 94 LS models came with the 4.62 gearing, and the 3.0 SOHC. The DOHC was in the SR models. I always wondered how misinformation came out, now I understand.

Whew! That was a trip. 3.0 sohc and 4.62 gears. Ultimately it seems a gen 2.5 winter would not make an ideal parts donor (engine and axles) for an ls, unless it was a 97.

Thanks, this definitely helps.

It would be a perfect donor for an early LS, your 98 has stronger axles and the locker plus more hp.

I've been lazy (actually a seemingly unfortunate side affect of the Montero accident) and was thinking of small potatoes peripheral parts swaps rather than vital organ transplants...but your point is dully noted.

This crappy air is certainly not helping anyone's motivation either, aside from a slight chance of rain for Sunday there seems no end to it for another week.

Older LS models will have the 3.0, I believe all with the 4.88 gearing. You can confirm the gearing and engine with the placard in the engine bay.

I havea 96 LS, been trying to figure out what gearing it has, what on the placard would tell me what gearing it has? I dont see anything pointing me in the right direction. Thanks!

Cannot remember the proper text
But I think it "axle trans" and should have numbers like 4.63 or 4.88
The numbers are the diff ratio for the vehicle

Should be 4.63 gears. But because is LS and not SR has smaller diameter gears.... At least in the front, probably rear too... So I don't think you can just swap with SR. But you should be a LR to pull the front axle housing and axles from an SR.

But best to check the sticker on the front and rear diff housings

I think the FSM for the gen 2 also has a page on the ratios and gear sizes. I might have posted a photo of the relevant section in 2014 when I swapped my gen 2.5 gears with gen 2 SR.... Moved me from 4.29 to 4.63

Just checked my 3.0 95 LS, gears are 4636

 

[SD_Montero]

Thanks for your help, looks like they are 4.636 gears. No problem running 31"s then? And is there a straight forward LSD I could install in this? Thx

I run 33s on my 463 gears on my 99. No issues
