Comp Cams Hi-Tech Hydraulic Lifters


  • Greater bleed rate increases vacuum
  • Increases throttle response for extremely hot street and racing applications
  • Pre-load can be set between .030"-.060"
  • Not recommended for extended street use
The variable duration Hi-Tech™ Lifters from COMP Cams® were designed primarily for extremely hot street machines or racing applications where a vacuum rule is in place or where you must run a hydraulic cam. They have a greater bleed rate, which greatly increases vacuum, throttle response and noise. Hi-Tech™ Lifters are not recommended for extended periods on the street.
