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-liter (SOHC) petrol engine. Around the same period, General Motors, Isuzu and Honda established a working relationship that saw the two-box design of the 5-door Trooper designed by GM with Honda providing petrol engine options and Isuzu providing diesel engine options. Under this partnership the Trooper was thus sold in Japan as the Honda Horizon (1994 to 1999), in Europe as the Opel Monterey, in the United Kingdom as the Vauxhall Monterey (1994-1998), in Australia as the Holden Jackaroo (1998-2002), and in the United States as the Acura SLX (1996 to 1999). The Trooper received a mid-life facelift in 1998 with new grille, bumper, headlamps, and front fenders. The rear received a body-colored, hard spare-tire cover. The 1998 Australasian and US-spec Trooper became equipped with the DOHC 3.5-liter engine from the Isuzu/Holden Rodeo producing . European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the 4JX1 3.0-liter of ).

Transmission options included a five-speed manual transmission, the Aisin AR5 and the electronically controlled 4L30E 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. While US-spec Troopers came only equipped with five seats, elsewhere in the world a seven-seater version was also offered. Optional on all models was a rear limited slip differential. In the US the three-door RS model was sold only from 1993 to 1995. The Trooper LS and S models offered cargo space, while Limited models had .
