Dress up that old 12 valve with our billet aluminum individual valve covers! With extra clearance for valvetrain and studs, they will fit perfectly on your daily driver or hotrod! They are roughly .250 taller than the factory covers. We have tested these to fit without grinding or milling on ARP and A1 studs applications. One of the best features that we have incorporated is the O-ring seals to eliminate the messy factory valve cover gasket! Includes all-new stainless socket head bolts.
Our Duramax LBZ, LMM, LML billet aluminum intake crossbridge will help you get the horsepower you need. If you are looking for more power, increased airflow, and perfect fitment every time, this high flow bridge is what you need. Available for all year model Duramax Engine from 2001-2015. Each intake features 2 – 1/8″ NPT threaded holes to connect a boost gauge and or injectables. The center hole is tapped for the factory IAT sensor.
