There's an Allen head screw under a cap on the same side as the pressure line. Next to the pressure line is the pressure relief, and you can adjust the pressure up by going in with the Allen-head. Do not adjust pressure without a pressure gauge. If you turn it up to high, you will blow all o-rings in all hydraulic system!
Negative ghost 👻 rider. When Towing’s 4,000lb Ford Taurus with this 1 ton 3500 with a 12,000lb GVWR minus the 6500lb truck and the 1500lb unit. We are fully in the realm of the GVWR that the truck was designed for. So anytime you tow a vehicle that is the same size or bigger that mentality would be appropriate, but the GVWR of these trucks is so high today you can tow passenger vehicles legally within the gross vehicle weight ratings.
