• Drivetrain — Full-time shaft-driven 4WD with 6 mm stub axles, steel front CV driveshafts, hardened steel rear axle shafts, remote locking steel gear differentials (cable-actuated), and a steel gear transfer case.
• Transmission — Two-speed high/low range with remote shifting, dual horizontal shafts, twin friction-plate slipper clutch, and easy serviceability.
