Pro Magnum Hydraulic Lifters
COMP Cams® Pro Magnum™ Hydraulic Lifters are specifically designed
to perform at higher engine speeds. When engines are equipped with a
hydraulic lifter, high rpm is limited by the improper position of
the internal piston as the lifter inevitably “pumps up”. This
improper location results in open valves and therefore leads to lost
power or sometimes even engine failure.
COMP Cams® Pro Magnum™ Hydraulic Lifters offer a distinct advantage
over standard high performance hydraulic lifters, especially in race
applications where a hydraulic lifter must be used. When tested in a
Chevrolet 468c.i. Big Block, the power increase was significant (see
chart to left).
Note: Adjustable valve train required, preload to .002”-.004” w/
