The 1992 Chevrolet Suburban specs are simple: a 5.7-litre V8 was standard, a 7.4-litre V8 was optional on 2500 models, and a four-speed automatic handled shifting. It is a body-on-frame, 131.5 in wheelbase, 3/4-ton-capable truck that seated up to nine.
Quick answer: 5.7L V8 (about 210 hp in 1500 form), optional 7.4L V8 (about 230 hp and 385 lb-ft) on 2500s, four-speed automatic, 2WD (C series) or 4WD (K series), 131.5 in wheelbase, roughly 219 in long, seating for up to nine. Towing depends on series, axle ratio and equipment, so there is no single rating.
1992 Chevrolet Suburban specs at a glance
The figures below come from General Motors’ 1992 Suburban information kit and Chevrolet’s published history. Treat them as factory references, because the condition and equipment of a 30-plus-year-old truck vary.

Engines and drivetrain
Both V8s were gasoline units with electronic fuel injection, and neither was supercharged. The 4WD K series used a two-speed transfer case, while 2WD trucks carried the C prefix.
Torque for the 5.7L is commonly quoted at 300 lb-ft. Check the VIN and underhood labels, since engine and axle choices varied by order.
Towing capacity
There is no single towing number that fits every 1992 Suburban. Rating depends on 1500 or 2500 series, 2WD or 4WD, engine, axle ratio and whether the factory trailering package was fitted.
That package added a hitch platform, wiring, and extra engine, transmission and radiator cooling. Before towing with an old truck, confirm the GVWR on the door label and the condition of the brakes, cooling system and transmission. For other SUVs, see our SUV towing capacity chart.
Fuel economy
Expect low fuel economy. The EPA’s 1992 Gas Mileage Guide lists a 2WD 5.7L Suburban at roughly 11 mpg city and 17 mpg highway under that era’s test method, which is about 21 L/100 km city and 14 L/100 km highway. Real results depend on condition, gearing, load and speed.
Buying a used 1992 Suburban in Canada
Condition matters far more than the model year. Road salt makes rust the main concern on Canadian trucks.
- Inspect the frame, body mounts, brake lines, rocker panels and rear wheel arches for rust
- Check the cooling system, transmission behaviour and fluid leaks
- On K series trucks, confirm the 4WD engages in high and low range
- Match the engine, axle ratio and GVWR to your planned use
- Check Transport Canada’s recall database, and ask your province about safety inspection requirements
Trims and how it compares with a modern Suburban
Cheyenne was the base trim and Silverado the upscale one. Chevrolet’s information kit does not list an LT trim for 1992, so be cautious if an ad claims one.
A modern Suburban is far larger, safer and more efficient; see our 2025 Chevrolet Suburban specs for the current truck, or the compact Chevrolet S10 Blazer specs if you want something smaller.
