Kei Truck Hulling
With the proper preparation and attention to these guidelines, you can enjoy a variety of adventures with your Kei truck while ensuring your payload capacity remains safe and manageable.
Kei trucks boast a payload capacity of 771 lbs (350 kg) for speeds up to 63 mph. However, depending on the model's engine and brakes, the payload capacity can be as high as 880 lbs at speeds up to 50 mph and up to 1,000 lbs for models with 45+ HP and acquit brakes at speeds up to 40 mph.

Kei Truck Towing
Kei trucks can tow loads of up to 880 pounds with speeds up to 55 mph. Kei truck models, which boast power outputs of 45+ horsepower and have acquit brakes, can tow up to 1,000 pounds at speeds up to 45 mph.
Safety & Limits
It is essential to highlight that Kei trucks are not specifically engineered for heavy loads. The engines can not handle high pressure at high rpm, and the frames are very light. If you carry over 771 pounds in the bed or tow over 880 pounds, stay away from high RPMs and it is recommended to upgrade the Kei truck brakes or use a modified trailer equipped with its own trailer-breaking system. Additionally, upgrading to wider or larger tires can enhance the truck's suspension, stability, and braking performance.
