Interior
The "deluxe" interior comes in gray or tan (gray only in XLC2).

adjustable up/down, forward/back, tilt forward/back, and reclining seat back.
The rears are fixed. Power door locks and windows are standard.
The "fleet" interior is available for XLC2 only - gray interior,
crank windows, and no radio.
The standard radio is a Delco Sound System with AM/FM/Cassette. The Monsoon
Sound system with CD changer is available for HMC4 and HMCS models.
Powertrain/Suspension
The 6.5L non-turbo is standard (NA in CA). The improved 6.5L turbo diesel
is available as an option (required in CA). The 4L80E 4-speed automatic is
still the only transmission option.
The differentials still come with the Torsen torque biasing units. A
Detroit Locker is available as an option for the rear for a true locked
performance (fleet only). Turbo diesels have the 2.56 ratio while the N.A.
diesels retain the 2.73. The Goodyear Wrangler MT 37x12.50/16.5 tires are
standard.
The 10,300 lbs GVW is standard. For fleet use, a 10,800 lbs and 12,100 lbs
GVW packages are available. The 10,800 is just spring upgrade. The 12,100
changes the springs, shocks, brakes, halfshafts, and some reinforced
suspension members.
Optional Equipment
B02: Heated Windshield Electric heating elements embedded in the front windshield like a rear
defroster.
A04: Central Tire Inflation System (CTIS) The HUMMER's unique tire pressure control system that allows
tire pressure to be adjusted while moving. The system consists of an underhood
air compressor and various valves, tubes, and gauges. This option is factory
only (very difficult to add later). Requires A89 Beadlock or A83/B83 Runflat Tire System w/Beadlock.
A09: Cruise Control
A30: 12,000 lbs Winch Adds a 12,000 lbs Warn Mil-12000 electric winch to the front for
vehicle recovery.
A32: Driveline Protection Consists of 5 shields to protect the underbody from damage off-road. 3
tubular steel cages protect the front and rear differentials and brakes and
the engine and transmission. 2 plates protect the fuel tank and transfer case.
A33: Brush Guard The brush guard can be added to a vehicle with or without a winch and
is intended for protection from brush only.
A59: Body Colored Wheels The wheels are painted the same color as the body instead of gloss
black.
A73: Trailer Towing Unit Adds a Class 3 hitch and electrical connections.
B74: Rear Defrost XLC2 (2 door) and HMC4 (4 door hard top) only. Adds an electric
defroster for the rear window.
B75: Rocker Panel Protection Adds aluminum plates to protect the body under the seats from the
front to rear wheels. It also protects the sides from the doors down. The
plates extend to the drivetrain tunnel but do not extend into it (see A32 Driveline Protection).
A83: Runflat Tire System w/Beadlock Adds a spacer inside the wheels that perform two functions. It holds
the inner bead to the rim flange to prevent sudden tire deflation from side
loads off-roading, esp. under reduced tire pressure (see A04 CTIS), i.e.
includes A89 Beadlock. The second function is to support the tire after losing air
pressure, allowing the vehicle to be driven slowly (30 mph) for a short
distance (20 miles) without any air pressure. Runflat operation may damage the
rim, tire, and runflat spacer. A83 is for vehicles without the 1GA package
(see B83).
B83: Runflat Tire System w/Beadlock (for 1GA) Same system as A83 Runflat tire system. This option is for vehicles that have the 1GA package
that contains A89 Beadlock. The runflat spacer is substituted for the beadlock
spacer (credit given for A89).
A89: Beadlock Provides the beadlock function described in A83 Runflat Tire System without the runflat capability. Included in A83/B83 Runflat Tire System w/Beadlock
A93: Highway Touring Tires Replaces the Goodyear Wrangler MT radials with Goodyear Wrangler GS-A
radial tires. The GS-A has a less off-road tire intended for better highway
performance.
A96: Power Mirrors Driver and passenger mirrors electrically adjustable for tilt and pan
from a control on the dash.

10,300 to 10,800 lbs for extended high GVW operation (fleet). XLC2 (2 door)

Requires the turbo diesel engine.
A35: Fuel Tank Shield Adds the fuel tank shield from A32 Driveline Protection.

rear axle. The Detroit is an automatic locker so some artifacts may be felt on

X42: Delete Standard Radio/Power Windows (XLC2 w/
Std. Interior)
