Namura provides high-quality piston options to suit a wide range of applications, including direct OEM replacements, high-compression variants, and multiple oversizes. B (0.01 mm) and C (0.02 mm) oversizes are also available, helping to extend the service life of expensive plated cylinders. Select applications are supported with big-bore piston kits. With the addition of MOS2 coating and hard anodising, Namura delivers improved performance and durability, without the premium price.

Features:

  • MOS2 (Teflon/Molybdenum) Coated Skirts: Applied using a rolled-on process for a bond up to 10 times stronger than typical spray coatings. Improves heat transfer, reduces friction, and helps prevent cold seizures.
  • Machined Smooth Heads: Reflect combustion heat and minimise carbon build-up, protecting the piston crown. Testing indicates potential gains of up to 6% in horsepower and fuel efficiency.
  • Anodised Domes: Enhance heat resistance and durability, with up to 75% greater strength compared to non-anodised pistons.
  • Hypereutectic Casting Process: Increases silicon content to reduce expansion, improve wear resistance, and withstand higher cylinder temperatures.
  • 0.50 mm oversize up to 100.47 mm, with a 9.2:1 standard compression ratio.
  • Includes piston (individually wrapped), OEM-quality rings (boxed separately), wrist pin, and circlips.

Great plates for the holidays and family gatherings!
Size: Extra Large (Pack of 1), Size: Extra Large (Pack of 1)
These plates are sturdy and designed to hold even the heaviest of meals without bending or folding, which is a huge plus when you're serving barbecue or pasta dishes. One of the standout features is their size; they’re large enough to accommodate generous portions, making them perfect for parties or picnics. I also appreciated the attractive design, which adds a nice touch to the table setting. Cleanup was a breeze, as they are disposable and save me from the hassle of washing up after the event. Additionally, they don’t soak through easily, so I didn’t have to worry about any leaks or messes, even with saucy foods. Overall, I highly recommend Dixie Ultra Large Paper Plates for anyone looking for a reliable and stylish disposable plate option. They combine functionality with aesthetic appeal, making them a perfect choice for any occasion!

Sturdy and Reliable Plates for Any Occasion!
Size: Extra Large (Pack of 1)
The Dixie Ultra Large Paper Plates are truly impressive in quality and design. They feel incredibly sturdy, living up to the promise of being 3X stronger than standard paper plates. I love the 11-inch size — it’s perfect for big, heavy, and messy meals without worrying about leaks or spills. The soak-proof coating and microwave-safe feature make them super convenient. The design is also bright and festive without being too flashy. These plates are now a must-have in my kitchen for family dinners and parties!

Strong Enough for BBQ Ribs, Pasta & Everything in Between!
Size: Extra Large (Pack of 1)
These Dixie Ultra paper plates are truly the heavyweight champs of disposable dinnerware. I grabbed them for a backyard BBQ, expecting the usual paper plate struggle—but these held up like actual dinner plates. We piled on ribs, baked beans, coleslaw, and even mac & cheese, and not a single plate buckled, soaked through, or leaked. At 11 inches, they’re large enough for full meals (and seconds!), and the cut-resistant coating means no forks poking through. They're also microwave-safe, which is great for leftovers. Whether it's dinner with kids, hosting guests, or avoiding dishes during busy weeks—these are now my go-to. Totally worth it!
