- The GMT400-based Suburbans were introduced in December 1991 for the 1992 model year. The similar pickup truck models had switched to the newer platforms in the 1988 model year. Both 2WD and 4WD models, designated "C" and "K", were offered, as well as half ton and three-quarter ton ("1500" and "2500") models.
- The base engine for all variants was the small-block 5.7 liter (350 cu in) V8. The big-block 7.4 L (454 cu in) V8 was optional for the 2500 series. The optional 6.5 L Turbo diesel was available on all models – though rare on the 1500 series. The 6.5 L Turbo diesel used in the Tahoe was detuned to 380 lb⋅ft (520 N⋅m) torque due to the limitation of the 8.5-inch (220 mm) axle capacity. 1500 Suburbans with the 6.5 L Turbo diesel used the 14 bolt axle from the 2500 series. Ground clearance was 6.9 inches, the approach angle was 18 degrees for the K-1500 (28 degrees for the K-2500) and the break over angle was 18 degrees.
- Transmissions included the 4L60 four-speed automatic in the 1500 series, and the heavier duty 4L80 four-speed automatic in the 2500 series and the 1500 series fitted with the 6.5 L Turbo diesel. The manual transmission option from the previous generation was dropped.
- The GMT400 series introduced independent front suspension. The 2WD models used coil springs and 4WD models used torsion bars in the front suspension. All models used a live axle and leaf springs in the rear.
- 0–60 mph time for a 1995 Suburban was 9.3 seconds. Top speed of a 1995 Suburban is governed on the engine for economy. A maximum of 98 mph (158 km/h) can be obtained. City fuel economy was 13 mpg‑US (18 L/100 km) and highway was 15 mpg‑US (16 L/100 km). The turning circle was 47.8 ft (14.6 m). In 1996, fuel economy had improved to 17 mpg‑US (14 L/100 km) highway.
- Trim options included a base-level version, the LS, and the LT. Interior seating arrangements allowed for either bucket or bench seating in the first row, and optional third row bench. The vehicle could be configured from two- to nine-passenger seating.
- Beginning in 1994, GM began making numerous annual changes to the Suburban, including:
- Revised front clip and center stop lamp (1994)
- Revised interior including a driver-side air bag, revised side mirrors (1995)
- Revised Vortec L31 (350 cu. in.) and Vortec 7400 (454 cu. in) engines with increased power and fuel efficiency, electronic 4WD shifting, daytime running lights, illuminated entry, and some new interior features (1996)
- Revised transmissions, improved steering system and added passenger-side air bag (1997)
- Onstar, PassLock security system and full-time AutoTrac 4WD option added, next generation "depowered" air bags, revised steering wheel, transmissions revised again (1998)
- No major changes upon introduction of redesigned 2000 models (1999)
