ROSS includes forced pin oilers and double spirolox on all of their stocking pistons. Pistons are balanced to plus or minus 2.5 grams throughout the set. You can buy replacement pistons one at a time as needed. The valve pockets are designed to handle most camshaft applications. The skirt design allows the pistons to work properly under intense heat and tremendous side loads without scuffing or splitting cylinder walls. Most normally aspirated pistons are designed to operate at .004 piston skirt to cylinder wall clearance. All ROSS stocking pistons include aircraft quality pins that are heat treated and end ground to work in full floated or press fit applications.

Molnar Technologies H Beam rods are machined from billet 4340 steel, and then heat treated to provide improved strength. To make the rods even stronger, they are shot peened to which also increases fatigue life. All Molnar connecting rods are fitted with highly durable premium bronze bushings for use with floating pin type pistons. Each rod set includes ARP fasteners, moly lubricant and installation guidelines.
All Molnar rods are finished in the United States at the Molnar Technologies shop in Michigan. Critical rod dimensions are are held to very precise tolerances of +/- .0001 of an inch, which is the tightest tolerance you will find in the performance and racing aftermarket.
