Crane Cams Hi-Intensity ''Fast Bleed'' Hydraulic Lifters

Product images may differ from actual product appearance.

Crane Hi Intensity lifters produce a "variable duration effect". At lower RPM this can reduce running duration by 6-10° and decrease valve lift by .020-.030". Hi Intensity lifters work best with a cam that requires more compression ratio than the engine actually has. Hi Intensity lifters restore vacuum, cylinder pressure and bottom end performance. As RPM increases, these lifters act more like a normal hydraulic lifter. At 2500 to 3000 RPM they will transmit the full duration and lift of the cam. Use only if the engine's compression ratio is below the minimum recommended on the application page for the cam you have chosen. Hi Intensity lifters can cause *low speed detonation* if compression is too high. Slightly more noisy than standard lifters (NOT as noisy as a mechanical cam) and can trigger knock sensors. Maximum RPM Potential: 6500 to 7000 RPM.
