A pressure supply unit for a brake system including a booster body that defines an axially extending cylinder. A piston is slideable within the cylinder. The piston defines a bore that receives a spindle. The spindle is rotationally fixed and axially moveable for providing the axial movement of the piston. A motor is positioned about the spindle and is configured to axially translate the spindle and piston. A ball and socket joint connects the piston and spindle while accommodating pivoting movement of the spindle. The ball and socket joint includes a ball at a front end of the spindle and a socket in the bore of the piston which receives the ball.

A concurrent leveling system includes a pressurized air source. A manifold block, having a body defining an air feed inlet, is disposed between air springs and the pressurized air source. The body includes front and rear suspension valves. Each of the suspension valves defines a suspension valve orifice having a first predetermined diameter. The body includes at least one restrictor valve parallel to and in fluid communication with the front suspension valves. The at least one restrictor valve includes a first check valve and a first blocker valve orifice defining a first orifice diameter. The first check valve and the first blocker valve orifice are disposed parallel to one another and in series with the front suspension valves and in fluid communication with the air feed inlet and the front suspension valves for reducing fluid back flow to allow the vehicle to be lowered in nominal loading conditions.
