Product Description

The ARB 320303 is the OEM piston and barrel service kit for ARB's full range of CKSA12, CKMA12, CKMTA12, CKMP12, and equivalent 24V on-board and portable air compressors. When a compressor loses output pressure or exhibits reduced performance due to worn piston seals or a scored barrel, this kit provides all the components needed to restore the unit to factory specification. ARB compressors are purpose-built to be rebuildable, and the 320303 is one of the core service kits that makes long-term field maintenance possible.

Designed to M5/M6 fastener specifications and manufactured to ARB's quality standards, this kit avoids the cost and downtime of full compressor replacement. Confirm your compressor model uses M5/M6 hardware specifications before ordering. ARB recommends having piston and barrel servicing performed by a trained ARB distributor or authorized installer to ensure correct assembly and seal integrity.
