Jeep: Locking diff question

A lot depends on which rear axle you have, what size tires you have, and
what you are trying to do. Except for serious off roading, a limited slip is
usually better than a locker.

Limited slip units are much tamer on the street, and fare a little better in
the snow. Lockers are also called "low side finders" in the snow.

The standard rear axle (Dana 35) will not last long with a locker and large
tires (over 33") with any kind of abuse. The Dana 44 will stand up much
longer.

I am searching for an alternative to 4WD, primarily pulling boats up wet
boat ramps. If I can lock both rear wheels, I would have the same effect
as a regular 4WD, sort of. In both cases 2 wheels have to be spinning to
be stuck, on a locked 2WD rear axle it would be both rear wheels. On a 4WD
it is one front and one rear wheel spinning. Limited slip is very useless
for the most part, I have been stuck on ramps with LS rear ends on 2WD and
you thought you were running an open diff.

Since my application is pretty specific, I could use a ARS (sp?) locker
that would not engage until I wanted it to. I was just wondering if the
locker is something you add to the existing diff, or do you have to
replace the whole rear end.??

Respectfuly, his logic is flawed. A measure of the total traction possible
is not proportional to the measure of how many wheels spin when you are
getting NO traction. In a 4X4 with open diffs, when no wheels are slipping,
all 4 wheels exert the exact same energy towards propelling the vehicle. If
one of your rear wheels slips, then both front wheels will still be
propelling the vehicle until the rear wheel stops slipping.
 

I have only driven one vehicle with an LSD. I felt no slipping even when I
tried to make it slip (way fun!). But then again I wasn't trying to drive up
a wet hill under load either. In that instance a locker may be more
effective than LSD. But I still say 4X4 with open diffs will be far superior
to 2WD with a locker. And aren't lockers noisy when they're unlocked?

I missed a key..

This is supposed to say: "Respectfuly, this logic is flawed."

For what it's worth ... it's not my 4WD that I find so useful for pulling
the boat up certain ramps ... it's the 4WD LOW. I've tried 4H on some ramps
.... and the wheels spun ... but not when in 4L ... Jeep Command-Trac ...
beauty, eh

Actually both wheels with a open diffs always propel vehical equally.
They alway recieve same torque (though RPM may be different, the torque
is the same) as a open diff can do it no other way
