The 2000 Tahoe Z71 is the last‑year, off‑road‑oriented special built on the GMT400 platform. It’s not just badging: the package bundles skid plates, 46 mm Bilstein shocks, a locking rear differential, 265/75R16 all‑terrains, brush guard, taillamp guards, and a monochrome look with color‑keyed flares, grille and bumpers. Most trucks also came with AutoTrac “AUTO 4WD” and […]
The 2000 GMT400 Chevrolet Tahoe Limited is the last‑year, RWD‑only special edition that kept the GMT400 alive alongside the new GMT800.

Why this truck matters: The 1992–1994 full‑size, two‑door Blazer is the short‑wheelbase GMT400 SUV that bridged the old K5 era to the later Tahoe nameplate. It brought independent front suspension, 4‑wheel ABS (’93+), and true “shift‑on‑the‑fly” 4WD—yet kept the simple, durable TBI 5.7L V8. In ’94, Chevrolet briefly offered a factory 6.5L turbodiesel, making these […]
Built on the GMT400 architecture, the Suburban 2500 is the three‑quarter‑ton version of Chevy’s long‑roof workhorse. It pairs the classic nine‑passenger SUV formula with heavy‑duty running gear—8‑lug hubs, stout axles, big‑block and diesel options, and serious tow ratings. This guide focuses on 2500‑series (C/K 2500) Suburbans for 1992–1999, with the goal of being your single […]

This guide covers the 1500 (½‑ton) models from the 1992 redesign through the 1999 final year, with powertrains, trims, axle ratios, year‑by‑year changes, […]
Chevrolet’s 454 SS is the poster child of the GMT400 “OBS” era: a regular‑cab, short‑bed C1500 stuffed with a throttle‑body–injected 7.4L big‑block and built to cruise Main Street. Launched for 1990 and produced through 1993, it started with a 230‑hp/385‑lb‑ft 454 and TH400 3‑speed/3.73 gears, then leveled up for 1991–1993 with 255 hp/405 lb‑ft, the […]
The C/K 3500 sits at the top of the GMT400 lineup as the 1‑ton workhorse, offered in SRW (single‑rear‑wheel) and DRW “Big Dooley” forms with 8‑lug running gear, heavy‑duty brakes, and stout drivetrains. Across 1988–1998 (plus 1999 “Classic” run‑out), buyers could spec everything from small‑block gas to 7.4L big‑block and 6.5L Turbo Diesel, backed mostly […]
