Valve Covers

Trick Flow® Billet Aluminum Valve Covers for GM LS

Trick Flow® billet valve covers are precision CNC machined in the USA from 6061-T6 aluminum and finished in durable black anodizing for a clean, high-end appearance. Designed with added clearance for shaft mount roller rocker arm systems, they are compatible with stock and aftermarket GM cylinder heads. An integrated oil drip rail helps reduce leaks while also aiding alignment during installation and removal. Driver and passenger side -12AN O-ring ports provide flexibility for crankcase ventilation systems, including catch cans and vacuum pump setups, while the included dyno-tested high-flow baffle system promotes efficient crankcase ventilation and minimizes oil vapor escaping through the PCV system. The baffle system is shipped uninstalled, allowing for additional valvetrain clearance or alternate PCV configurations when required. Each set includes a billet oil cap, stainless steel hardware, and uses factory-style gaskets for a secure, reliable seal. Optional universal coil mounting brackets fit GM LS and many aftermarket coils, or allow for remote mounting for a cleaner engine bay.
