COMP Cams Hydraulic Lifters A-CRS-CRB

If you're working on an AMC or Jeep 6-cylinder engine from the mid-60s through the late 80s, these COMP Cams High Energy hydraulic lifters are a solid option. They're built to precisely meter oil to your rocker arms, which helps prevent over-oiling at higher RPMs and keeps things running smoothly. This is important because consistent oil flow means better lubrication and longer life for your valvetrain components.

What sets these lifters apart is their patented orifice metering valve design. This system maintains continuous contact with the pushrod seat, which is made from a heat-treated, powdered metal iron alloy for strength and wear resistance. You also get a longer piston than you'd find in conventional lifters, giving you more surface area for load bearing and ultimately increasing how long the lifters last. The lightweight check valve disc inside also allows for quicker response, meaning your engine can rev up faster before experiencing valve float, and it helps maintain control across all engine speeds and loads.
