2382701PK Piston Kit Fits Caterpillar Models

One New Aftermarket Replacement Piston Kit for Caterpillar (Cat) C9 Diesel Engines

This aftermarket replacement piston kit fits the Caterpillar C9 8.8L six-cylinder diesel engine. The C9 is a common power plant used across a wide range of Caterpillar construction and on-highway equipment. Piston kits for the C9 typically include the piston crown, skirt, rings, pin, and retainers -- everything needed to restore compression and upper-end performance during an engine overhaul or inframe rebuild.

Important Engine Serial Number (ESN) Restriction

This piston kit is compatible with Caterpillar C9 engines with ESN prefix 9DG, as well as prefix variants CKP, MTB, SRB, THY, and THYX for industrial and on-highway applications. Verify your engine serial number prefix before ordering, as multiple piston designs were used across C9 production runs and mismatched pistons will cause fitment and performance issues.
