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.
