Performance Level 4Level 4 camshafts are designed for heavily modified engines.

A higher lift rate will RPM less, needs more spring pressure and lighter valve train components.

HFTCs & lifters require less maintenance than mechanical camshafts.

Hydraulic lifters operate with an internal cushion of pressurized oil.

Intended for performance hot street/strip and performance marine applications, these profiles have a moderate lope at idle and offer an extended rpm range with emphasis on upper bottom to top end power and a strong mid-range.

These higher lift, longer duration camshafts demand close attention to rear end gearing and tire diameter combinations.
