Size Over Standard: +0.01mm
Note: Kit Includes Both Pistons
- Includes pistons, rings and top end gasket sets (and needle bearings when needed)
- Machined smooth piston crown (unless otherwise noted) to reflect combustion heat while reducing carbon buildup
- Hard anodized piston crown with a hardness of HRB 105
- MOS2 coating to draw heat through piston walls and out the bottom
- Minimized piston expansion and contraction
- Pistons are more resistant to wear and scuffing, expand less with heat and are stronger
- Higher Performance piston without a higher price
Provides you with all the necessary components to complete your rebuild: these include a top-end gasket set, pistons, rings, wrist pins, circlips and silver coated SCM415 high strength chromoly needle bearings where needed.
Piston:
MOS2 (Teflon/Molybdenum) Coated Skirts: A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures.Gaskets:
Namura gaskets are manufactured to OE-specs, which means no trimming or fitment issues. Our materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities as well as tested using ASTM standards. Each design is evaluated against rigid quality-control standards to ensure each set meets or exceeds OE performance. Clutch gaskets are available for certain applications.Brand: Namura
