Complete lifter kits for Big Twin models from 1948 thru 1999. Each kit includes lifter blocks, VelvaTouch lifters, pushrods and pushrod covers. The lifter blocks are manufactured with a tough cast iron alloy to closely match expansion rates of the lightweight steel lifters and maintain precision tolerances even when the engine is hot. A patented oiling system provides each lifter with its own independent supply of oil to ensure proper lubrication and enhanced tappet operation. The hydraulic lifters are performance engineered with the use of strict quality control and the highest grade materials available. Lifter wall thickness is optimized to provide both strength and light weight to deliver solid lifter performance with hydraulic lifter quiet and convenience. The pushrods are manufactured from .049" wall, 4130 chrome-moly steel and they provide the ultimate in reliability and performance. Kits are available with stock length pushrods as well as with .250" longer ones for stroker applications. Lifter blocks are available in your choice of black or chrome finish. Each kit is packed in a small case and includes a video tape with "step by step" mounting instructions.
