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.
