3.21 or 3.43 in the 14 bolt both are hard to find used. 3.54 is the highest in a d60. 3.54 with 235-85-16 tires works nicely for me up to 70 mph with a non overdrive trans. BC

The gm large full size cars in the 70's that diesel engines in them used 2.73 gears.
It is 5 bolt 4 4 3/4 I think. I have one behind my v6 with granny 4 sp. It cruises
good at 70. With a overdrive it might be to high geared.

[QUOTE=BarryGMC;47521]For the rear use an Izusu rodeo/Honda passport D44. It has disk brakes. Usually a trac lock 3 series carrier with a thick 4.09 ring gear and six bolt axles. These are 95.00 in the pick and pull yards. These are 1/2 inch narrower than the stock D44 in our GMC's .


Sounds like a way to put rear disks on your truck if you liked the 4.09 gears.

Thanks BarryGMC

I believe 3.54 is tallest I can get for my D60.
Which is fine with me. Just trying to get an idea
of what to look for.
Also lot of talk about change of carrier. Do I need to
do this for a 4.10 to 3.54 swap?
Dumb question department. Is a D70 to D60
compatible?

The carrier is fine for this swap. The d70 is bigger than a 60 not much swaps over. BC

I have a D44 in my truck and would like to speed it up a little as it is it's wound up pretty tight at 50. So what are some of the possibilities to swap in maybe a 3:50 ratio? Is there a carrier break between low & hi ratio's?...Vernski:):)

Re: Rear end parts most dont think of
 
Hi Vernski. 3.73 and higher is the break. Check what you have on the tag or on the ring gear. BTW I live in spokane. I have lots of d44 powerlock carriers and gear sets and a few complete rears. BC

If you have a DANA 44, you can go with Precsion Gears and go as low as 3.23 as I have.
