We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It uses compressed air to reduce the pedal effort required to disengage the clutch, making driving easier and reducing driver fatigue. The cylinder is typically replaced when it develops air leaks, the clutch pedal becomes stiff, or the assist function fails completely. It is an OEM-quality component suitable for repairs on Mack vehicles with mechanical (cable) clutch linkages that incorporate air pressure assistance.
