Vehicle Fitment

• Universal — Compatible with ARB CKMA12, CKMP12, CKMTA12, and CKMTP12 12V Air Compressor systems; confirm your compressor model number before ordering

Fitment Notes

• Universal service part — not vehicle-specific; designed as a direct replacement compressor assembly for compatible 12V ARB single and twin motor compressor models
• 12V only — not compatible with 24V ARB compressor models; the 24V equivalent is PN 320106
• Compatible models: CKMA12 (Single On-Board), CKMP12 (Single Portable), CKMTA12 (Twin On-Board), CKMTP12 (Twin Portable)
• ARB recommends having compressor servicing and assembly replacement performed by a trained ARB distributor or authorized installer
• ARB compressors are designed to be rebuildable — this assembly is part of ARB's comprehensive compressor service parts program

Features

• OEM ARB medium compressor assembly engineered to factory specifications for 12V single and twin motor compressor platforms
• Direct replacement assembly — restores full compressor output and performance when the original assembly fails or wears
• Individually bench-tested at the factory before packaging to ensure correct operation
• Motor is 100% ball bearing equipped with a unique linear brush pre-load system for extended service life, low heat generation, and quiet operation
• Compressor piston equipped with a German-made, high-shock-rated cylindrical roller bearing for durability in demanding off-road conditions
• Constructed from lightweight, high-strength engineering-grade materials including military and aerospace-grade components
• Extends the service life of the ARB compressor without requiring full unit replacement
• Part of ARB's rebuildable compressor design philosophy — spare parts readily available through ARB's authorized dealer network

Product Description

The ARB CKM01SP is the OEM 12V medium compressor assembly replacement for ARB's CKMA12, CKMP12, CKMTA12, and CKMTP12 on-board and portable air compressor systems. When a compressor assembly fails due to wear, overload, or damage, this direct replacement restores the unit to factory specification without requiring full compressor replacement. Each assembly is individually bench-tested at the factory before packaging to verify correct output and performance.

ARB compressors are purpose-built to be rebuildable, and the CKM01SP is one of the core service assemblies that makes long-term field maintenance possible. The motor uses a 100% ball bearing construction with a linear brush pre-load system for extended service life and quiet operation, and the piston assembly features a German-made cylindrical roller bearing for high-shock resistance. This assembly is 12V only — confirm your compressor model before ordering. The 24V equivalent is PN 320106. ARB recommends installation by a trained ARB distributor or authorized installer.
