Isky's patented anti-pump-up hydraulic Superlifters outwardly appear similar to standard hydraulic lifters, but there's a world of difference. The design of the lifters allows the use of a more radical cam, without loss of compression and horsepower from valves being held off their seats. Because they don't bleed down completely, they are also far more durable and reliable than any other lifters on the market. Power Hydraulics are premium-quality stock replacement hydraulic valve lifters.
