Our complete listing of all available Ross Pistons products is here > Ross Racing Pistons Catalog |
ROSS dome top pistons feature forced pin oilers when applicable, anti detonation grooves, lock removal grooves and come complete with wrist pin retention lock rings. They are pin fit and balanced to plus or minus 2.5 grams throughout the set. Intake and, or exhaust valve pockets are radius machined and designed to handle most common high performance camshaft applications. The precision skirt design allows the pistons to work properly under intense combustion heat and tremendous side loads without scuffing or splitting cylinder walls.
If you do not find the set here with the specifications that you need we also offer pistons from many other manufacturers as well as custom dome pistons for most any engine project. Please contact us if you need help locating the parts you need, or if you want to discuss a set of custom pistons and we will be happy to work with you to make sure you get exactly the parts you need.
