Pistons & Cylinders

pISTONS & CYLINDERS for Porsche 356 - 912

Pistons are one of the most important components in engines. All our pistons are modeled and designed exactly according to the 3D CAD models of the JPS Aircooled cylinder head.

 

Complete CNC machining of the piston on the outside and inside. So we are able to reduce the piston weight to an absolute minimum without reducing the stability or durability of the piston.


Kolben sind eine der wichtigsten Komponenten in Motoren. Alle unsere Kolben werden exakt nach den 3D-CAD-Modellen des JPS Aircooled Zylinderkopfes modelliert und konstruiert.

 

Komplette CNC-Bearbeitung des Kolbens auf der Außen- und Innenseite. Somit sind wir in der Lage, das Gewicht des Kolbens auf ein absolutes Minimum zu reduzieren, ohne die Stabilität oder Haltbarkeit des Kolbens zu beeinträchtigen.
