Enginetech Stock Replacement Camshafts

Enginetech stock replacement camshafts are direct-fit OE specification cams designed to restore original factory performance, idle quality, and drivability during engine rebuilds. They're available in hydraulic flat tappet, hydraulic roller, and solid flat tappet styles. Order the duration specs and other options preferred for your application.

Key features and manufacturing:

* OE specifications: Profiled to match original factory lift, duration, and lobe separation angles (LSA) so fuel economy and torque curves remain unchanged
* Quality control: Manufactured at OE facilities using strict Statistical Process Control (SPC) data and rigorous metallurgy checks, including Rockwell hardness testing
* Application range: Available for a vast array of domestic and import engines, ranging from classic inline-six and pushrod V8 blocks to modern truck applications (such as GM LS/LQ series)
* Installation requirements: Designed for standard rebuilds; proper break-in procedures utilizing assembly lube and zinc/ZDDP additives are heavily emphasized by Enginetech to prevent premature wear
