The high performance flat top pistons for Datsun L-series everyone has been waiting for. We had these pistons made to handle twice the chamber pressure allowing you to build a engine over 300HP using our Hypopeutectic Pistons. Unlike Hyperpeutectic pistons our pistons will not crack under extreme stress. We added an accumulator groove to increase ring seal and increase power. Our pistons come with ceramic coated crowns and Teflon skirts. We positioned the top compression ring higher in order to increase complete fuel burn. We went with modern ring thickness of 1.2 1.2 and 2.8 to increase engine efficieny. Piston wall thickness is 4mm and crown thickness is 12mm. Pistons come with our light weight wrist pins and performance ductile iron rings. These pistons will be heat pressed onto your existing stock rods. Not made for bushed rods.

Compression Height is 38.1mm SAME AS OEM FOR L-Series

Casted from very strong ADC12 Japanese Aluminum Alloy
