What is the best way to increase towing capacity in a Toyota Hilux?

I currently have a Toyota Hilux with a towing capacity of 3,500 lbs. Is there any way to increase this without causing damage to the engine or transmission? I occasionally need to tow heavier loads and I don't want to risk damaging my vehicle.

One option is to install a stronger suspension system. This will help distribute the weight more evenly and reduce strain on the engine and transmission.

Another option is to upgrade your towing hitch to a higher weight capacity. This will allow you to tow heavier loads without putting too much strain on your vehicle.

You could also consider getting a bigger engine for your Hilux. A larger engine will have more power and will be able to handle heavier loads more easily.
