The 9th generation of Suburbans was introduced in 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 5.7L V8. The big-block 7.4L V8 was optional for the 2500 series. The optional 6.5L turbo diesel was available on all models, though rare on the 1500 series. The 6.5L turbo diesel used in the Tahoe was detuned to 380 lb·ft torque due to the limitation of the 8.5-inch (220 mm) axle capacity. 1500 Suburbans with the 6.5L 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 4-speed automatic in the 1500 series, and the heavier duty 4L80 4-speed automatic in the 2500 series. 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.
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 3rd row bench. The vehicle could be configured from 2- to 9-passenger seating.
