The DSP40 is a heavy-duty, single‑speed front differential featuring a power divider air lock, commonly installed in Class 8 trucks. It uses a 41‑spline axle connection and a 44‑spline input. Replacing a worn or failed DSP40 restores proper front axle engagement, eliminating driveline noise, vibration, and preventing further damage to related components.
