* Engine: The 5.7L V8 had a higher towing capacity than the smaller engines.
* Axle Ratio: Higher axle ratios (like 4.10) allowed for greater towing capacity.
* Transmission: The type of transmission (automatic vs. manual, and the specific transmission) impacted towing ability.
* Equipment: Options like a towing package significantly increased capacity. This package often included a heavier-duty cooling system, transmission cooler, and other components.
Therefore, there's no single answer. To find the *precise* towing capacity for your specific 1996 GMC Suburban K1500, you need to:
1. Check the sticker on the driver's side doorjamb. This sticker lists the vehicle's specifications, including towing capacity *if it was originally equipped for towing*.
2. Consult your owner's manual. This will provide the towing capacity for your specific configuration, assuming you have the original manual.
3. Check the glove compartment. Sometimes a supplemental sticker detailing towing capacities was located here.
Without this information, providing a number would be inaccurate and potentially dangerous. Always check the vehicle's documentation for the correct towing capacity before attempting to tow anything. Towing beyond the rated capacity is extremely unsafe.
