If someone has *added* air shocks later, the correct pressure would depend entirely on the brand and model of the aftermarket air shocks installed. The manufacturer's instructions, usually found on the air shock itself or in accompanying paperwork, will specify the recommended pressure range. This pressure will also vary depending on the load you're carrying.
To find the correct pressure, you need to:
1. Identify the brand and model of the air shocks. This information is usually stamped on the shock itself.
2. Locate the manufacturer's instructions. These instructions will give you the pressure range.
Without knowing the specific air shocks installed, it's impossible to give you a safe and accurate pressure. Using the wrong pressure can damage the shocks or compromise your vehicle's handling and safety.
