Ferrea Lightweight Pro Solid Lifter is precisely that weighing in at just 59 grams. Forged from super clean Tool Steel alloy ensures greater molecular density, increased resistance strength and durability to higher levels of compressive stresses. Dyno and track tests have proven with Ferrea Lightweight Pro Solid Lifters plus Ferrea Hollow Stem Lightweight Valves cranks out an additional 500-650 RPM more by reducing approximately a pound of reciprocating mass from the motor. Forged reinforced pushrod seat ensures reliability and pressurized oiling lubrication when using high valve spring pressures at high RPM levels. Critically lubricated through a .025” EDM’d hole for increased oil delivery at all times and extend cam lobe-face to lifter cycle life for today’s sophisticated and demanding Oval Track cam profiles.
