Ross Small Block Chevrolet Flat Top Piston Standard Features

ROSS pistons feature forced pin oilers when applicable, anti detonation grooves, lock removal grooves and come complete with wrist pin retention lock rings. The pistons 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 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.

Custom 17 Degree and 18 Degree Valve Angle Pistons

If you do not see a set here with the specifications that you need we also offer pistons from many other manufacturers as well as custom forged pistons for most any engine project. Please contact us if you need help locating the pistons you need, or if you would like to discuss a set of custom forged pistons and we will be happy to work with you to make sure you get exactly the parts you need.
