Year of production 1991 - 2005

Model: Trooper / Bighorn (1981 - 2002)

Wikipedia (Trooper / Bighorn):

In 1991 for the 1992 model year, Isuzu completely redesigned the Trooper to keep pace with changes in the SUV marketplace, making it larger, more powerful, and more luxurious. These 4,155 lb (1,885 kg) vehicles used a 3.2 L 177 PS (130 kW; 175 hp) (SOHC) petrol engine or 3.2 L dual overhead cam (DOHC) version rated at 193 PS (142 kW; 190 hp). A SOHC 3.2 L engine producing 193 PS (142 kW; 190 hp) was introduced in 1996, replacing the earlier engines. Most models still used a part-time four-wheel-drive system, which required stopping the vehicle to engage and disengage the front axle. Starting with the 1996 SE Limited Troopers came a "shift-on-the-fly" engagement system.

From 1992, the UBS-series was available with a pushrod overhead valve (OHV) 3.1 L in-line 4-cylinder intercooled turbodiesel (designated "4JG2") producing 114 PS (84 kW; 112 hp) at 3,600 rpm, and 260 N·m (192 lb·ft) at 2000 rpm. It was offered as as a more rugged and fuel-efficient option for towing and heavy-duty operation, relative to the standard 3.2-litre petrol. The diesel-powered Jackaroo was available with a five-speed manual transmission and manual front hubs only coupled to a part-time 4wd system with open front and limited slip rear differentials. The 2.283:1 low range can be selected on the move, providing the front hubs are engaged, at up to 15 km/h 1st gear, 25 km/h 2nd gear and 40 km/h 3rd to 5th gears (the 3.2-litre V6 petrol engine version was also available with an optional four-speed auto and auto locking front hubs). The same diesel engine was also available in Great Britain and other markets with a belt-driven overhead camshaft, which developed slightly more power. After 1998, and the introduction of the "4JX1" 3.0-litre diesel engine, a four-speed automatic transmission was made available in addition to the five-speed manual transmission.

The Australian version of the UBS-series was sold as the Holden Jackaroo/Monterey. In July 1993, Holden Special Vehicles also launched 79 HSV Jackaroo models, which were just a cosmetic upgrade to Holden donor powered by the same 3.2 L 177 PS (130 kW; 175 hp) (SOHC) petrol engine. Around the same periodd, Isuzu and Honda established a working relationship that saw Honda sell a rebadged Trooper. The car was thus sold in Japan as the Honda Horizon (1994 to 1999) and in the United States as the Acura SLX (1996 to 1999).

Beginning in 1998, the US-spec Trooper became equipped with a DOHC 3.5 L engine producing 215 hp (160 kW; 218 PS). European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1 L (later superseded by the more problematic 4JX1 3.0 L of 159 PS or 117 kW). A Borg-Warner torque-on-demand all-wheel-drive system was introduced, along with freshened styling. The grille was redesigned again for the 2000 model year.

Transmission options included a five-speed manual transmission, the Aisin AR5  and the electronically controlled4L30E four-speed automatic. The 4l30E was fitted with both a "power" shift feature allowing the gearbox to take better advantage of the engine's power by adjusting the shifting nature and a "winter" mode permitting third gear starts for added stability in slippery conditions. The 2000 to 2002 Trooper included a feature called "Grade Logic" which allowed the transmission to automatically downshift on steep grades in order to slow the vehicle down.

The suspension consisted of a fully independent torsion bar front suspension, and a multilink coil sprung rear suspension integrated with a solid rear axle.

The Trooper LS and S models offered 117.8 cu ft (3,340 L) cargo space, while Limited models had 112.3 cu ft (3,180 L).

While US-spec Troopers came only in the 5-seat models, in Europe and the UK 7-seater version was also offered. Optional on all models was a rear limited slip differential. In the US the 3-door RS model was sold only from 1993 to 1995.

In 2002, the Trooper was discontinued in the United States in favor of the smaller Axiom and the larger GM-produced Isuzu Ascender, a re-badged GMC Envoy.

A Trooper with the 16-valve 159 PS (117 kW; 157 hp) 3.0-liter 4JX1-TC engine was sold in the Philippines from 2002 until model year 2005. Known as the Skyroof Edition, it came in a rear-wheel-drive configuration with anti-lock brakes, a limited slip differential, billet-type radiator grille, and large power moonroof. Other standard options included leather seats, wood trim, and a VCD entertainment system. It was later succeeded by the Isuzu Alterra.
