KM 4BT Billet Valve Cover – Notched for Stock Lines (032513-1N) fits Cummins w/stock lines
$472.45
The KM 4BT Billet Valve Cover 032513-1N is a one-piece billet aluminum upgrade for Cummins 4BT 8-valve engines running stock injection lines. Notched for OEM line clearance, the KM 4BT Billet Valve Cover 032513-1N stands 3.25″ tall to clear most aftermarket studs and helps stabilize rocker pedestals under higher spring pressure. Sealed with individual O-rings, it delivers durability, proper fitment, and a clean billet appearance.
KM 4BT Notched Billet Valve Cover 032513-1N
The KM 4BT Notched Billet Valve Cover 032513-1N is engineered for Cummins 4BT 8-valve engines that retain factory injection lines. This one-piece billet aluminum design features precision notching to properly clear stock fuel line routing while delivering the strength and rigidity serious diesel builds demand.
Unlike universal billet covers, this version is specifically machined to accommodate OEM line positioning without modification. That means proper fitment, cleaner installation, and no interference concerns when maintaining factory fuel configuration.
Designed for Cummins 4BT with Stock Injection Lines
This billet valve cover is notched to fit directly over stock injection lines. If your engine runs aftermarket lines that route over the top or around the cover, a non-notched version is available separately.
With a total height of 3.25 inches, the cover sits taller than stock and clears most aftermarket head studs. The additional height also improves internal clearance for upgraded valvetrain setups.
Billet Construction with Functional Strength
Beyond appearance, this aluminum valve cover adds structural rigidity across the rocker pedestal area. The one-piece design helps reduce flex under higher spring pressures and increased RPM, making it a strong choice for performance-focused 4BT applications.
Each unit seals to the cylinder head using individual O-rings for consistent sealing and simplified service compared to traditional gasket systems.
The top surface is engraved with the Keating Machine logo. Custom engraving or a non-engraved version is available upon request. A -12AN breather port can also be added if desired — contact before ordering for custom configurations.
