The boyz at the Mopar Underground have surfaced and they've premiered a fascinating collection of vehicles that they've been working on behind the scenes.

What follows is a brief rundown of the Psychotic Six.  We'll have a detailed overview of these rigs in the August issue of Four Wheeler and the coverage will include off-the-hook photography of these rigs going psycho in the sand.  You won't want to miss it.  For now, feast your eyes.  

Hemi JK: This black JK is called the "JKL" and it has a 110-inch wheelbase, 37-inch tires, a 4-inch suspension lift and a lusty 6.1L Hemi V-8.  Can you say POWER-TO-WEIGHT ratio?

Dana 60 JK: Called the "All-access," this JK premiered at the '07 SEMA show, but it's being trotted out again to highlight a new mod; the upcoming "MILITARY-SPEC" and "performance-upgraded" Dana 60 rear axle that will be available through Mopar Performance.

Diesel TJ: This rig is an engineering mule that has been fitted with the 2.8L 4-cylinder DIESEL engine.  It was built to explore the feasibility of integrating a diesel engine kit in the TJ vehicle system.  It has an Aisin 5-speed and an NV241 t-case.

Cummins Power Wagon: Yep, they FINALLY built one!  It's sporting the 6.7L Cummins diesel along with 40-inch tires, a KORE suspension and all the usual smokin' PW goodies.  Drool.

J8 Sarge: Oh man, where to start?  This  ULTRA-COOL non-combat military support vehicle has a 116-inch sheelbase; Dana 60 rear axle set on leaf springs; a 2.8L turbodiesel engine; hood-mounted air intake snorkel; and much more.  It's made in Cairo, Egypt.

Liberator II:  A Liberty like no other, this KK has a rear ARB Air Locker, rock rails, brushguard, cat-back exhaust, 33-inch tires and a 2-inch lift.  Will the Liberty now get some RESPECT?

Mopar trotted these vehicles out to gauge consumer reaction, so hey, feel free to react.  Don't hold back.  Weigh in with your thoughts on Mopar's latest design exercises.
