SKU:10008P2
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
Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%
Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons
Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures
The NAMURA NA-10008-2 OEM Style .020 Oversize Piston Kit is designed for engine rebuild and replacement applications requiring a piston matched to a .020 oversize cylinder specification. Built for powersports and small-engine service work, this kit provides a practical replacement solution when restoring engine performance and renewing worn internal components. The OEM-style design supports a familiar fit and installation approach for qualified technicians and experienced rebuilders.
Use this NAMURA piston kit during a properly measured engine rebuild where the cylinder has been bored or otherwise prepared for the applicable oversize piston. Correct piston-to-cylinder clearance, ring end gap, wrist-pin fit, and related component specifications should always be confirmed before installation. Because engine applications can vary, verify the manufacturer’s service information and compare the original component, bore specification, and year, make, and model compatibility before ordering or assembling the engine.
The kit format helps simplify replacement planning by providing the piston assembly as a dedicated service component rather than requiring the piston to be sourced separately. NAMURA is recognized for producing replacement engine components for repair and maintenance applications, and this OEM-style piston kit is suited to rebuilders seeking a direct, specification-focused replacement option. Follow all applicable installation procedures, use the correct assembly lubricant, and inspect the cylinder, connecting rod, wrist pin, circlips, and related parts for wear or damage before final assembly.
This kit is identified by part number NA-10008-2 and is supplied as one kit. It is intended for users who need a NAMURA .020 oversize piston replacement and should be selected only after confirming application details and the required oversize specification. Proper measurement and professional installation are essential for reliable operation, service life, and safe engine performance.
