4QK4003A is a Mack rear spring assembly from the suspension group, built as an aftermarket replacement for Mack suspension applications.
A heavy-truck spring assembly is a main load-carrying part of the suspension: it carries the load of the truck and its cargo and keeps the axle positioned under the chassis. When a wheel hits a bump the spring flexes to soak up the shock, then rebounds so the tires stay in contact with the road. A tired spring shows itself as a truck that sits low or leans, bottoms out over small bumps, or squeaks, rattles and clunks, and cracked leaves call for prompt attention.
It is sold as a single unit (1 each) by Pro Gear and Transmission.
