PRO-TEK HIGH PERFORMANCE HYDRAULIC LIFTER - HL-1817HP

Pro-Tek lifters feature premium grade/high strength material and an ultra-strong steel retainer to precisely limit plunger travel and allow the valve train to perform as a mechanical system for high RPM performance and stability.

Engineered and manufactured to the highest quality standards, these lifters’ oil metering valves are tailored to the specific Chevrolet engine application to deliver precise lubrication of the overhead valve train components. The ball design check valve provides outstanding response and reliability. Plunger and check ball springs are precisely balanced to allow uniform operation at high speeds.

Hydraulic lifters require the proper pre-load to be set.

High Performance lifters require adjustable rocker arms.

Designed for Chevrolet 112-454 CID – 1955-86 engines.
