COMP Cams Hydraulic Lifters Cadillac/Bu

If you're rebuilding the top end of your Buick 181-252 Odd-Fire V6 or 198-225 Even-Fire V6, these High Energy Hydraulic Flat Tappet Lifters from COMP Cams are a solid option. They're designed to ensure precise oil delivery to your rocker arms, thanks to a patented orifice metering valve that maintains continuous contact with the pushrod seat. This design helps prevent excessive oiling at higher RPMs, keeping things controlled.

The pushrod seat itself is made from a heat-treated powdered metal iron alloy, built for strength and wear resistance. You'll also find these lifters have a longer piston than conventional designs, which means more surface area for load bearing and ultimately, increased longevity. The lightweight check valve disc is another key feature, allowing for quicker response and better control at all engine speeds and loads, helping to increase engine speed before valve float occurs. These lifters fit a range of vehicles, including many Buick models like the Century and Skylark, as well as select Oldsmobile and Pontiac applications from the 1970s and 1980s.
