ROSS Racing Pistons are used in high performance and racing engines by knowledgeable engine builders the world over. One of the most important factors in achieving maximum engine efficiency and power, is the critical seal between the piston, rings and cylinder walls. Precise machining of the piston and especially the ring lands leads to improved sealing.
High output engines also put huge loads on the piston, both physical and thermal. Using a forged piston is standard in most all high performance and racing engines these days. Forgings are preferred in order to have the strength and durability required to survive in high output applications.
The compression ratio is another critical factor and one that must be chosen based on many factors such as the intended use, type of fuel and octane to be used. In some cases such as certain restricted racing classes there are limits as to what compression ratios can be used.

All ROSS stocking piston sets include wrist pins, forced pin oilers, pin fitting, lock removal indents and pin lock rings. Sets are balanced to plus or minus 2.5 grams. You can buy replacement parts one at a time as needed. The valve pockets are designed to handle most camshaft applications. The skirt design allows for proper operation under intense heat and tremendous side loads without scuffing or splitting cylinder walls. Most normally aspirated sets are designed to operate at .004 skirt to cylinder wall clearance. The sets also include aircraft quality wrist pins that are heat treated and end ground to work in full floated or press fit applications.
