AC Piston
Detroit Diesel

The piston component used in the vehicle’s air conditioning compressor is designed to deliver reliable compression cycles within the A/C system, contributing to efficient refrigerant handling and consistent cooling performance. Engineered to tolerances that minimize blow-by and maintain steady displacement, this piston supports stable compressor pressure ratios across varying ambient temperatures and engine loads. By preserving sealing integrity and reducing friction through precise manufacturing, the piston helps extend compressor life and maintain peak cooling capacity, which translates to improved occupant comfort and system durability even in demanding climates. The part is associated with the A/C subsystem category and is intended for direct integration into the OEM compressor assembly, ensuring compatibility with the platform’s lubrication, timing, and valve mechanisms. It is a strategic replacement item to restore original performance, protect the compressor from surge-related wear, and reduce the risk of abnormal noise or reduced cooling output during heavy-duty operation.
