Product Details
COMP Cams is well-known for performance valvetrain components, and these Pro Magnum hydraulic lifters are a prime example. If you're working on a Buick 181-252 V6 engine, these lifters are built to handle higher engine speeds than stock units. They are specifically designed so the internal piston stays in the proper position, preventing the lifters from 'pumping up' excessively at higher RPMs, which can cause issues.
This unique design can lead to a notable power increase over standard hydraulic lifters. They have a .842-inch diameter and a seat height of 2.01 inches, weighing in at 94 grams each. Keep in mind that an adjustable valve train is required for proper setup, and you'll want to set the pre-load between .002" and .004" with the engine warm.
These lifters fit a wide range of vehicles, including many Buick models like the Skylark and Special from the 60s and 70s, as well as some Jeep Cherokee, Comanche, and Wrangler models from 1991.
