19 Spline Powerloc

PowerLoc DANA 44 Differential 4.09 - 4.55 Ratios (1968-1985)

 

"Will fit:
Jaguars 1968-1985 Model XJ62.8 with Ring Gears 4.09 - 4.55
Will also fit Jeep 3/8 Ring Gear using spacers 4.10 - 5.38"

Is this correct?

 

I don't know, but doesn't the case break go 3.56 or so to 5.38?

 

I don't know about the case break, but I've dealt with this guy before and he seems quite knowledgeable.

 

Most Jaguars with IRS from the early 1960's though the late 1980's have D44 powerloks. They are 19 spline, and commonly are 3.07, 3.31, 3.54 or 3.77 ratio. The later XJ6's can has 2.88 or 4.09 ratios, so both 3 and 4 Series Powerloks are found in Jags, though the most common are 3 Series.
Does anyone have an "alternate source" besides Bronco for the D30 powerloks? I'm still looking for one for a 3.73 ratio.

I think early Scouts used D30 rears. Did they use powerloks?

 

27 rear end, with powerlok
There's one of those in the front of my Jeep

 

So were saying this won't work for an ECJ D44?

 

Volvo 1031 axles used them. Late model 240s and any 740s might have them.

 

I guess I will start posting powerlocks here as I am happy to get $250 for one.

 

4 series 30 spline? $old!

 

Jeep never used a 4 series 30 spline though. Some Fords did but I don't buy anything Ford unless it is a GPW cause they weren't really a Ford, just built in a Ford factory. Better to go Detroit or selectable if a newer 30 spline. If still running old 19 spline stuff, a powerlock is great.

 

If you're asking if the Jag Powerloks will work in a Jeep, I'm 99% sure it will, I just haven't actually done one yet. I have several Jag rears with the Powerloks, and they even have a "PL" tag on them. They used to be pretty common in the U-Pull yards, but they are a real pain to pull apart in the junkyard. You pretty much have to drop the whole rear suspension to get the diff out.
