These cylinders are cast of a specially-formulated iron alloy that s charged with a much higher chromium content than is typically used. This results in improved ring compatibility and much better wear resistance. The RevTech® cast iron alloy demonstrates greatly increased strength at elevated temperatures and resists thermal shock loads 2.4 times greater than conventional cast iron. The RevTech® cylinder design strengthens the casting s foundation and its greatest weak point ... the base. Even the cooling fins have drawn the attention of RevTech® engineers they have been re-designed for greater heat dissipation. There is an attention to detail and ease of assembly that isn t commonly found in high-performance products. The special design base nuts offer greater strength while the cylinder base nut reliefs are fully machined to insure clearance for both the nut and a normal closed end wrench, so they can easily be tightened to the correct torque specifications. RevTech® cylinder head bolts are forged from 4140 chromemoly steel, then heat-treated. Even the gaskets are of a special design and material that is formulated to adhere under the most extreme heat and pressure. Sold in pairs.
