The maximum weight that GMC Sierra 3500HD is allowed to tow. The maximum trailer weights listed are only applicable for altitudes up to 3280 ft (1,000 m) above sea level. With increasing altitude the engine power and therefore the car's climbing ability are impaired because of the reduced air density, so the maximum trailer weight has to be reduced accordingly. The weight of the car and trailer must be reduced by 10% for every further 3280 ft (1,000 m) (or part thereof).
This is the maximum amount of weight GMC Sierra 3500HD is rated to carry (engine, chassis, fluids, passengers, cargo, load - everything). It is often determined by the manufacturer and is indicated in the owner's manual or on the inside of the drive's door panel.
This is how much GMC Sierra 3500HD weighs sitting on the curb with no driver, passengers, no cargo and no load with all standard options.
Payload is considered all the extra stuff you put inside your vehicle, whether it be passengers or a pile of rocks, that weight is all considered payload. You can increase it by:
The higher the power of your engine, the more weight your car can pull.
It is the same for all trims.
High torque is essential for towing because it allows you to pull the trailer at a lower RPM, reducing the strain on the engine.
It is the same for all trims.
The higher the axle ratio, the more power your vehicle produces, and as a result, the more weight this car can tow.
All-wheel or rear-wheel drive vehicles are best suited for towing, while front-wheel drive vehicles can haul much less weight.
Do not overload your vehicle while towing, as this can cause the transmission to overheat and fail. If your transmission has "Towing mode" - be sure to turn it on.
Turbocharged engines produce more power, so if you need a vehicle for towing, choose the one equipped with a turbo.
The longer your vehicle's wheelbase, the less likely the trailer you tow will push down on the rear axle and lift the front end.
It is the maximum allowable weight that can be placed on a front axle of your GMC Sierra 3500HD.
It is the maximum allowable weight that can be placed on a rear axle of your GMC Sierra 3500HD.
When planning exhilarating outings outside, you will need to bear in mind the 2008 GMC Sierra 3500HD towing capacity, which is the key characteristic for such adventure. The towing capacity in reality is the vehicle's maximum amount of weight that it may safely tow. This info can generally be found on a sticker located within the driver's front door next to the door latch. The gross vehicle weight rating (GVWR) will be the optimum operating weight (including freight and passengers) and really should not be exceeded. Typically, the body weight of the trailer being towed is advised to be kept within 10-15 per cent of the GVWR.
Below, you may check out the info on the towing capacity of the 2008 GMC Sierra 3500HD with all trims and generations. You should be aware the maximum towing weight may vary depending on the braking system of what is being pulled. If your trailer features its own brakes then it is "braked capacity". If not, it is unbraked capacity. When buying the future RV, you must remember that its weight and ranking is provided by the the trailer's producer plus all of the additional payload you are likely to put in it needs to never surpass the 2008 GMC Sierra 3500HD towing capacity. Violating this important guideline will have an impact on your ability to handle and stop in time and can eventually bring about long-lasting problems for your automobile or even cause accidents on the roads.

The Society of Automotive Engineers (SAE) has developed the J2807 set of recommended practices. The tow test procedures designed by the big brains at the SAE consist of a series of rigorous real-world challenges to determine the Gross Combined Weight Rating (GCWR) of a vehicle and trailer combination.
