LS4 Excalibur Camshaft is now available separately!

At the heart of every Excalibur DOD Delete Kit, you will find our extremely popular camshaft. It is hard to say which aspect you will enjoy more, the choppy idle or the aggressive boost in horsepower. Beyond the proven performance associated with this grind, you can expect phenomenal drivability, even with the tight OE torque converter.

2007 Model Year Note: Starting in 2007, GM made the transition to a 1-Bolt camshaft as well as a new style chain dampener. To facilitate the camshaft installation on 2007 and newer LS4 engines, you will need a 3-bolt conversion kit.

Installation of this component will require a tune. Do NOT try to operate your vehicle after installation without consulting a competent tuner.
