COMP Cams Hydraulic Lifters Cadillac/Bu

If you're working on a Buick 350-455 V8 or a Cadillac 425-500 V8 from the late 60s through the late 70s, these COMP Cams High Energy Hydraulic Flat Lifters are a solid option. They're built to keep your valvetrain running smoothly by precisely controlling oil flow to the rocker arms, thanks to a patented orifice metering valve. This design helps prevent excessive oiling at higher RPMs, which is key for engine longevity and consistent performance.

The pushrod seat is made from a heat-treated powdered metal iron alloy, giving it good strength and wear resistance for the long haul. You'll also find these lifters have a longer piston than standard ones, which means more surface area to handle the load and extend their lifespan. The lightweight check valve disc inside helps the lifters respond quicker, allowing your engine to reach higher speeds before the valves start to float, and it maintains control across all engine speeds and loads.
