Four Seasons 4057R A/C Compressor Replacement Service Kit

The Four Seasons 4057R is an A/C replacement service kit designed to provide the essential components needed for a complete and reliable air conditioning compressor replacement. Four Seasons, a division of Standard Motor Products and the largest aftermarket climate control parts supplier in the industry, engineers these kits to ensure a thorough system repair—not just a compressor swap.

Replacing the compressor alone is not sufficient for a lasting repair. Debris and contaminants from a failed compressor can circulate throughout the A/C system, damaging the new unit prematurely. This kit includes the supporting components necessary to restore proper refrigerant flow and system integrity alongside a new or remanufactured compressor.

Key Features:

• Designed to accompany an A/C compressor replacement for a complete system repair
• Components engineered to meet or exceed OEM specifications for proper fit and function
• Manufactured in a TS16949 / IATF16949 certified production environment for consistent quality
• Helps prevent premature compressor failure by replacing wear-prone ancillary components
• Part of Four Seasons' trusted PAC-Kit replacement kit lineup
• Backed by over 45 years of automotive air conditioning engineering experience

Four Seasons 4057R is the dependable choice for technicians and DIYers who want to perform a thorough, warranty-conscious A/C repair. Always flush the system and replace supporting components simultaneously to protect your investment and ensure long-lasting, ice-cold performance.
