      Ross Racing Pistons 3SGTE 86.5mm Bore (.020 over)

      ROSS Toyota shelf stock pistons are made on the same forgings, are the same material, and include the same quality design features as their custom pistons. 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. Our valve pockets are designed to handle most camshaft applications. Our skirt design allows the pistons to work properly under intense heat and tremendous side loads without scuffing or splitting the cylinder walls. All ROSS stocking pistons include aircraft quality pins that are heat treated and end ground to work in full floated or press fit applications.
