How much can a 1991 S-10 4.3 tow?
A typical 1991 Chevrolet S-10 with the 4.3-liter V6 can tow roughly 4,000 to 5,500 pounds, depending on equipment and drivetrain. The exact limit depends on whether the truck has the factory tow package, whether it’s two-wheel drive or four-wheel drive, and other factory options. For the precise rating, check the vehicle’s data plate, owner’s manual, or a dealer VIN lookup.
What factors determine the towing capacity
The S-10’s ability to haul a trailer is not a single number. It depends on several interrelated factors, including the presence of a tow package, the transmission, axle gearing, brake setup, cooling capacity, payload, and the truck’s gross vehicle weight rating. In 1991, the 4.3L V6 was offered with different transmissions and drive configurations, which influenced the maximum trailer weight the truck was officially approved to tow.
Before looking at specific numbers, it helps to understand the typical configurations seen on 1991 S-10 pickups. The following ranges reflect common factory specifications for this model year when equipped with the 4.3L V6 and the relevant towing options.
- 2WD with tow package: up to about 5,500 pounds
- 2WD without tow package: up to about 4,000–4,500 pounds
- 4x4 with tow package: up to about 5,000 pounds
- 4x4 without tow package: up to about 4,000 pounds
These figures are the manufacturer’s maximum trailer weights for typical configurations of the era. Real-world towing should also consider payload, hitch rating, braking, and overall vehicle condition. Always stay under the combined limits to maintain braking and handling safety.
How to verify your truck’s exact rating
Because exact numbers can vary by trim, options, and any upgrades since new, confirm the precise rating for your specific truck before towing. Start with these sources.
- Door jamb data plate: Look for the Gross Vehicle Weight Rating (GVWR) and any stated towing capacity or GCWR (gross combined weight rating) shown on the plate. This is the official anchor for your truck’s limits.
- Owner’s manual: The manual typically lists the recommended maximum trailer weight for different configurations and hitch classes.
- VIN-based confirmation: If the data plate is missing, a GM dealer or a trusted online VIN decoder can pull the original factory specs for your exact truck and options.
- Hitch and brake system: Ensure the hitch class, receiver size, and trailer brakes (if required) are rated to handle the intended load and are compatible with the truck’s braking system.
After confirming the official rating, compare it to the trailer’s GVWR and hitch rating. The safe, legal towing limit is the smallest of the vehicle’s GCWR, hitch rating, or the trailer’s gross weight, minus any cargo and passengers.
Safety notes and practical guidance
With an elderly, light-duty truck like the 1991 S-10, towing safety hinges on more than memory of a number. Use an appropriate hitch, verify cooling capacity (radiator and transmission cooler if towing heavy loads), ensure your brakes are in good condition, and distribute payload properly between the truck and trailer. Drive conservatively, especially on hills and in inclement weather, and plan for longer stopping distances when towing.
Summary
In summary, a 1991 S-10 4.3 can typically tow around 4,000–5,500 pounds depending on whether it has the factory tow package and whether it’s 2WD or 4WD. For any trailer you plan to tow, verify the exact rating on the data plate and in the manual, and ensure all towing components (hitch, brakes, cooling) are appropriately configured. When in doubt, consult a qualified dealer or mechanic to confirm safe towing limits for your specific truck and setup.

How much can a S10 tow?
A Chevrolet S10 can tow between 3,100 and 6,000 pounds, depending on the specific model, engine, and configuration. The 4.3L V6 engine generally offers higher towing capacities, with some 2WD automatic models rated up to 6,000 lbs, while 4-cylinder engines are limited to lower weights. It's crucial to check your truck's specific owner's manual and the sticker on the driver's side door jamb for the exact maximum towing capacity for your vehicle.
Towing capacity by configuration
- 4-Cylinder Engine: The 2.2L 4-cylinder engine models have lower towing capacities, ranging from 1,600 lbs to 3,100 lbs depending on the transmission and axle ratio.
- V6 Engine: The 4.3L V6 models offer higher towing capacities.
- With a manual transmission, the capacity is around 3,900 lbs.
- With an automatic transmission, the capacity can be up to 5,900 lbs, especially with the ZR2 package.

Important considerations
- Check your specific vehicle: Always verify the maximum towing capacity for your exact S10 by checking the owner's manual or the sticker on the driver's side door jamb, as it can vary significantly.
- Don't exceed weight limits: Be mindful of the total weight, which includes the trailer and its contents.
- Safety first: When towing at or near the maximum capacity, it's recommended to add a transmission cooler and use a weight-distributing hitch to ensure a safer tow, as towing with an S10 can be challenging due to its shorter wheelbase.
- Brakes: The stock brakes on S10s can get hot under heavy load, so be sure to brake early and often.
