are there any different diff ratios you can put in a 1200 ute so it runs on the
highway a bit better.

so she doesnt rev her tits off

thanks guys

the diff cetre from a blue bird (TRX) fits into the 1200 ute housing. the ratio is either 3.9 or 3.7 where as the ute is 4.1. You could go the whole hog and fit the
rear disc brakes(sick).

thanks for that mark, i think its time to go looking for a trx diff!

A better option is to keep the standard diff ration and get an overdrive 5 speed if you can get one, but they're usually too expensive. The 1200 ute diff is shorter than a standard
1200/120Y diff - you can use these but if the motor is worked then you'll probably break the diff.

I think the bluebird and 200SX diffs (both disc brake and drum) are significantly wider than the 1200 one, but I dunno. Everyone I know who's bought one to fit has given up on it
in disgust.

The diff centres should fit though, and so should swapping the drums for bigger rear brakes.

Certain Bluebird models got a 3.9 and 3.7 ratio diff that fits straight in a ute diff housing.

I'd love a 3.7 ratio. I'd be able to use 1st gear for something. With the CA18 with a 3.9 I generally just use 2nd and 4th around town, and 5th if
going onto a freeway.

keep the ute diff. it has bigger axles than the stock sedan and coupe diffs. get hold of a series 3 blue bird 3.9 or 3.7:1 centre and bolt that straight in as the axles and
bearings are exactly the same. better yet, get hold of a complete diff with one of those centres and swap the disc brakes over as well coz they are a bolt on job same as the
diff centre.

that way you've got a good ratio, and disc brake arse end to boot.

i've got an overdrive 5 speed sitting in my shed for sale with a complete hydraulic brass button clutch setup to go with it.

$1000 take away as it is in top condition.

You wouldnt happen to have a left hand side axle lying around would
you?

right or left both the same

nah

only a spare ute diff housing itself with no axles or face plate
