Monster Box 3 Speed
Transfer Case
$2699.00
What’s included in our price:
Options:
How the “Monster Box”
is built
The Monster Box Transfer Case
housing is manufactured from cast 356 alloy aluminum and hardened to a
T6
condition. We fully CNC
machine the entire profile and bearing locations ensuring all tight
tolerances are
maintained. Our Housing
utilizes an extremely thick wall to guarantee that case deflection under
heavy
acceleration is not an issue.

The gears of the Monster Box are
manufactured from ASTM Alloy 8620 and heat treated to Rockwell “C” 58-
60. Our gears are
helical cut and very robust in comparison to other factory and
aftermarket transfer cases.
We DO NOT utilize Synchronizers in
our transfer case.
Gear Selection
We offer multiple gear ratios for
the Monster Box Transfer Case. The 3-speed transfer case gear
options are
as follows:
- 5.44:1, 3.05:1,
and 1:1
- 4.33:1, 2.43:1,
and 1:1
- 3.75:1, 2.05:1,
and 1:1
-
0.79:1, 4.33:1, and 1:1
Like our gears, the shafts of the
Monster Box are manufactured from ASTM Alloy 8620 and heat treated to
Rockwell “C” 58-60. We produce our output shafts in the Heavy Duty 32 spline
configuration. This allows you
a wide range of yoke options to fit
your individual needs.

Because we use 32 splines on
our output shafts, a large number of yoke and flange options are
available to
the consumer. We offer the
following:
- 1310
Non-CV
- 1310 CV
- 1350
Non-CV
- 1410 Non
CV
- 1350 CV
Flange
Our shafts will also accommodate
most 32 spline yokes and flanges from the aftermarket 4x4 industry.
Bearings
We use only the highest quality
bearings available. Our transfer case employs tapered roller
bearings on ALL
of the shafts, as well as caged
needle bearings on all internal gear to shaft transitions. We also
use radial
thrust bearings between all of the
gears and shafts as well.
Fasteners
We use in excess of 60 3/8-16
Stainless Steel Socket Head Cap Screws in our assembly to guarantee a
long
and durable life.
Clocking
Our Transfer Case is
clockable in 4 degree increments up to 360 degrees. This allows
the consumer to “fine
tune” the
installation for their particular needs.

We offer two different shifter
configurations. The first is our “Universal Shifter”. It consists of
either two or three
levers, horizontal to the front of the transfer
case. The consumer may pivot, shorten, and modify as necessary
to fit
their individual application. The second option is our “TJ” Style
shifter. This shifter is designed to fit
through the factory hole in a
Jeep TJ. Because of the innumerable variables in vehicles such as
transmissions, long arm suspension
systems, flat skid plates, Etc., slight modification to your floor or
console
may be necessary.

A rear output parking brake is
available as an option on all of our transfer cases. This
kit includes the rotor,
caliper, mounting brackets, rear
mounting flange, and all necessary mounting hardware. You will
need to
supply a handle and cable to
complete the installation. Some driveline modifications may be
necessary. This
kit can be retrofitted after the
time of purchase as well.

Our VSS is a factory
Jeep Rubicon sending unit. It is a direct plug in to 2003-2006 Jeep
Wranglers and is
easily adapted to the 1997-2002 Wranglers. If your
application utilizes a mechanical drive speedometer, then
you will need
to replace your factory speedometer with an aftermarket unit like the
ones from
Auto Meter
or
Dakota Digital. Our VSS sends three pulses
per revolution of the rear output shaft. If you need a different
signal
or pulse count, there are several aftermarket “signal
convertors” available.

4wd Light
We offer an optional “4wd light”
threaded hole in our transfer case. This option is required for
the Jeep
Rubicon as the 4wd light controls
the factory differential lockers. We do not supply the electrical
plunger
switch for this option. These
can be found in all 1997-2006 jeep vehicles with a factory NP231
Transfer Case.
