Liners

Add years to your engine’s life with induction-hardened cylinder liners. It’s not a magic trick.

IPD offers a full range of induction-hardened cylinder liners. IPD was the first aftermarket company to develop Induction Heat Treated cylinder liners. IPD liners became known as the “hard liners” and have a track recorded of extended durability. One of our IPD patented products is our original IPD Crevice Seal Style liners for Caterpillar® 3400 Series and C15 engines. These crevice seal liners offer a wider rectangular seal in addition to the two o-ring seals reducing the amount of cylinder liner movement and decreasing o-ring failure. IPD’s cylinder kits are available for Caterpillar, Cummins and Waukesha engines and include: pistons, rings, pins, retainers in addition to the cylinder liner.
