Hi pinion front diffs

Jafa · Post by **Jafa** » Tue Mar 21, 2006 1:11 pm

Okay boys, tell me what years, models, and ratios etc landcruisers have high pinion front diffs?
Will they fit the standard hilux housing,
I'm after a 4.88 High Pinion for my junk, I think out of a 80 series?
Cheers for any info

I can tell you that the 80 series does have a high pinion fornt diff. Most have 4.1 ratio though.

Would be a good way to get a factory cruiser locker into your truck though.

prados aswell, but as jungle said 4.1s are the most commons for the simple reason most of them are driven by diesels :oops:

,but you can get 4.88 ring and pinion kits............

but why you goin hp?have you a mega lift?or you using a prado housing with the reversed idler arm.......

My KZJ71 Prado SX & KZJ78 SX Prados 3lt has a 4'88 High Pinion Diff in the front with small side bearings ( reverse rotation gearing)

Not a mega lift, 100mm, but teh HP helps with driveline angles

I don't know if the HP Landcruiser diff head will fit a Hilux housing, but if you are going for a HP Landcruiser diff and plan to give it a bit of abuse, then make sure you get the later model double skin diff head. If you plan on giving it serious abuse then add a bit more strengthening.

that also is the one with the big cvs(if im correct),isnt it 93 onwards?........

A mate of mine fitted the complete front axle unit from a >1990 PZJ70 (5 cyclinder) in to his Hilux . It was a NZ spec model so the diff ratio was the same as his Hilux. This gave him Hi Pinion , Bigger CVs, & larger side bearings

i was led to beleive that all cruiser and hilux cvs are all the same size except the 80series

This may be of some use.

L/C from 91 on including Prado's 93 on have the larger CVs and run the 8"diffs

The diff head (Carrier Sub-Assy, differential, front) part number changed 08/1992. The CVs (Shaft Sub-Assy, Front Axle Outer) changed 08/1992, 04/1994 and 01/1995. I don't know what the significance of the changes are.

MU Front HILUX axle with 4.88 high pinion front fitted... direct bolt-in replacement for the standard 8" diff.

The 2.4TD Prados ran a 4.88 high pinion front... virtually everything else is 4.1 or 4.3 from memory.

Hope that helps

hmm that link dosent say anything regarding cv sizes (or i may of mis-read)

any body got any pics of the different sizes?

4wdnuts/i wonder if those part numbers are regarding the size difference just because in the early 90s they fitted a ring gear to the outter bell for the speed sensor to run on for the abs system :wink:

pics,pics ,pics.............

Thats exactly what I'm after....now do you have one to sell, or know of one :shock:

SupraLux · Post by **SupraLux** » Wed Mar 22, 2006 3:29 pm

Yep, you can have mine... $12,000... comes with a MU

Other than that, no... I had to search high and low (pinion :lol:

) to find that one... it was a lucky score when I got it... and I had to have it shipped down from up north somewhere...

Keep an eye on trademe, as there was a guy wrecking a 2.4 prado on there a while back... palmy nth or thereabouts from memory...

He needs a 4.88... that one is waaaay too high geared. By the time you re-gear it you'll have spent too much on it I think... better option, use that diff but get a fully worked 454 big block with blower

Just 1000 or so HP

Then you don't need to worry about ratios at all

I thought he could reuse his current R&P (dont know if its compatible).

Still worth shouting about, be pissed if it was okay but didnt know (I know I would be). ;-)
