Revitalize your Cummins ISX DOHC engine with the IPD Inframe Overhaul Rebuild Kit KIF1878/96, a comprehensive solution designed for the grueling demands of heavy-duty trucking.

Crafted to exceed OE specifications, it promotes smoother operation, extended engine life, and reduced maintenance for those endless highway miles or rugged off-road jobs without the failures of worn parts. Note: IPD does not include the oil pan gasket as per Caterpillar guidelines deeming it reusable; add it for an additional $149 if desired.
