Take Your Duramax Build Beyond Factory Limits

A serious engine build deserves pistons that are ready for more than ordinary driving, and the Industrial Injection 44B111 Coated and De-Lipped X-Series Piston Kit is built with that goal in mind. Designed for 2001-2016 6.6L Duramax engines requiring a .030 inch overbore, this complete matched piston set gives your rebuild the premium components needed for dependable performance. Every kit includes pistons, rings, wrist pins, and retaining clips, so you can spend less time sourcing parts and more time assembling your engine. The thermal barrier coating helps protect the piston crown from intense combustion heat, while the anti scuff skirt coating reduces friction to support long term durability. Furthermore, the de-lipped piston design is intended for applications that see elevated boost and increased cylinder pressure, making it an excellent choice for performance focused diesel builds. Whether your truck is built for towing, competition, or everyday driving with added power, this kit delivers the confidence needed to handle demanding conditions. It is a smart investment for anyone looking to build a stronger and more capable Duramax engine.

Engineered To Support High Demand Diesel Performance

The Industrial Injection X-Series Coated and De-Lipped .030 Piston Kit is precision engineered for 2001-2016 GM 6.6L Duramax LB7, LLY, LBZ, LMM, and LML engines that have been machined for a .030 inch overbore. Each piston is manufactured as part of a matched set to promote balanced engine operation and consistent performance across all eight cylinders. Additionally, the premium PVD ring pack provides excellent cylinder sealing while standing up to the increased demands of elevated boost, heavy towing, and high cylinder pressure. The thermal barrier coating on the piston crown helps manage combustion heat, while the low friction anti scuff skirt coating minimizes wear during cold starts and extended engine operation. The de-lipped piston profile is specifically intended for more demanding diesel applications where durability under load is critical. Because the kit is designed as a drop in replacement for properly machined engine blocks, installation remains straightforward while maintaining precise fitment. When combined with quality machine work and careful assembly, this piston kit provides the durability and reliability needed for a high performance Duramax rebuild.
