Diff Ratios


Front diff:
All models: C200.

Rear diff:
Light duty SWB (Europe and Middle East only): C200
Heavy duty SWB (All Australian models), wagon, van (except P40), ute: H233B
Heavy duty ute, P40 van: H260 (rare)

Ratios:
MQ SWB (4 speed):
L28 and SD33 - 4.625

MQ Wagon/Van (4 speed):
L28 and SD33 - 4.625
P40 - 4.11

MQ Ute (4 speed, H233 rear end):
SD33 - 4.625
P40 - 4.11

MK SWB (5 speed):
L28 and SD33 - 4.625
SD33T - 4.375

MK Wagon/Van (5 speed):
L28 and SD33 - 4.625
SD33T - 4.375
P40 - 4.11

MK Ute (5 speed, H233 rear end):
SD33, SD33T and P40 - 4.625

MK Ute (5 speed, H260 rear end)
SD33, SD33T and P40 - 4.88

I have updated the ratios section, it is a bit clearer and I fixed up an error. I have added in a couple of new engine/diff combos. I have never seen a H260 ute with an N/A SD33, but it was a combination that could have been ordered, so I added it.
If anyone has FACTORY diff ratios that are different to those shown above, send me a message with a pic of the build plate (see below) to confirm and I will add it to this post.

To confirm factory diff ratios there is a build plate behind the RH headlight, under transaxle there is a 4 digit code. 2 letters followed by 2 numbers.
HG: C200 front, H233B rear
HH: C200 front, H260 rear
43: 4.375 ratio
46: 4.625 ratio
48: 4.88 ratio

MQ: open front and rear diff
MK: open front and LSD rear diff

All axle and diff assemblies are interchangeable with all models provided the diff ratio is the same, or the centre is swapped so that the ratio is the same.
