Diesel Engine Rebuild & Inframe Kits

Rebuild your heavy-duty diesel right the first time. This collection covers inframe overhaul kits and major rebuild kits for the engines you run every day — Cummins, Caterpillar, Detroit, Paccar, Mack, Volvo and International — built around quality PAI Industries components. An inframe kit gets you pistons, liners, rings, bearings and gaskets to overhaul without pulling the block; complete-engine builds belong in our Dominator complete kits.

Not sure which kit fits your engine, serial range, or an OEM part number you already have? That's our specialty. Cross-reference your number or request a quote and we'll confirm the exact kit before you order. Ships same-day from Colorado.
