Housing

 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.

Gears

 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:

• 5.22:1, 2.97:1, and 1:1
• 4.29:1, 2.44:1, and 1:1
• 3.78:1, 2.15:1, and 1:1

Shafts

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.

Yokes and Flanges

 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 30 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.

Shifters

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.

Parking Brake

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.

Vehicle Speed Sensor

 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 converters” available.
