Caterpillar C15 Inframe Rebuild Kits

A Cat C15 inframe rebuild kit puts your Class 8 diesel back in service without pulling the block. These kits bundle the wear parts you replace from the top down: piston and liner assemblies, ring sets, rod and main bearings, and the gaskets and seals to seal it all back up. If your C15 is burning oil, blowing blowby, or down on power with high miles, an inframe is the cost-effective path to fresh compression.

Every kit here is built for the C15 platform. Not sure which configuration you need? Send us your engine serial or arrangement number and we'll match the exact kit.
