Crane Cams Anti-Pump Up Hydraulic Lifters:
Crane Cams performance hydraulic lifters provide precise oil metering control using Crane's exclusive check ball internal valving. The bleed rate of these lifters is maintained by microtolerances that prevent pump-up, which limits your rpm potential. After proper preload has been set, these lifters seldom need maintenance. Sold in sets of 16.

Both Crane's standard design and their ultra-lightweight Pro series are available.
