Hi Steve,
Where do you get this information telling you the Rubicon's 4.11
Tru-Lok is on the 3.73 size carrier? If so that would be right up there
with their "C" clip idea.

Hi Bill,

My best information is the Tru-Lok sitting on my bench beside an open
carrier that I pulled from an XJ D44 with 3.54 ratio. Same flange depth.

Read this blurb from Randy's R&P:

( http://www.ring-pinion.com/about/aboutyukondana.html )

"Randy's Ring & Pinion, a leading supplier of truck and off-road
differential parts, announces their distribution of the new Yukon Dana
44 4.88 thick gear sets for the 2003 Jeep Wrangler Rubicon"

"Yukon Gear engineered the 4.88 thick gear to mesh seamlessly with the
existing Rubicon lockers, the top-of-the-line Tru-Loc ™ air lockers.
With the computer-designed 4.88, Rubicon owners can push beyond the
limits of the standard 4.10 gear and can move from the 31" stock tires
up to beefy 37" tires. The thick ring gear set, made from high-quality
8620 steel, also works well in older Dana 44 rear-ends with a 3.73 &
down carrier case, eliminating the need for a new carrier case or locker."

The only disadvantage I can see with the need for a thick ring gear is
that they cost a bit more new and are harder to find used. Hassle factor
aside, I don't think there are any performance concerns that rank with
the C-clip.

Hi Steve,
Well, I'm still not believing Daimler would be so stupid. If this
Tru-Lok: http://www.----------.com/TruLok.jpg really is for the 3.73,
then I wouldn't want it because there would be too much leverage just to
one side of the housing causing it to crack like an egg. And the bones
of the Rubicon will litter the trail.
