Features:
If you’re rebuilding your 6.6L Duramax and want a piston set that blends proven reliability with performance-ready upgrades, the Mahle De-Lipped Cast Piston Set is the way to go. These aren’t your average cast pistons, they’re engineered to go the distance and built to handle the kind of abuse that comes with towing heavy, hauling hard, or chasing big power. With a de-lipped design that helps reduce stress in the combustion bowl, you get a smoother, more durable piston that’s ready to take the heat. The dry film lubricated skirts help protect during startup and break-in, while the phosphate coating works to prevent ring micro-welding and pin galling, two common failure points in high-compression applications. This kit includes everything you need: eight coated pistons, Mahle rings, wrist pins, and circlips, all ready to drop in. Whether you're freshening up a daily workhorse or building something that hits the rollers on the weekend, this kit brings confidence to your bottom end. It's a smart upgrade that works as hard as your truck does.
The Mahle 930036055 De-Lipped Cast Piston Set is engineered specifically for 2001 to 2016 GM 6.6L Duramax engines, offering improved reliability through precision design and advanced coatings. Each piston is cast from high-strength aluminum alloy and features a steel top ring land for added protection under high cylinder pressures. The de-lipped combustion bowl helps reduce stress risers, which in turn minimizes the risk of cracking under intense thermal loads. These pistons come equipped with phosphate coatings to prevent ring micro-welding and pin galling during early engine operation. Additionally, the skirts are treated with a dry film lubricant that reduces friction and promotes smoother motion during cold starts and break-in cycles. The kit includes a complete set of eight pistons, Mahle piston rings, wrist pins, and circlips, everything needed to complete a high-quality rebuild. This setup is ideal for performance builds, heavy-duty use, or anyone looking for a durable, OE-replacement piston with upgraded engineering. Mahle’s reputation for OE-quality and motorsports-proven components ensures this set delivers both performance and longevity.
