Katech VVT and DoD Delete Billet Covers
As you know by now, all Gen.5 LT engines are equipped with VVT “variable valve timing” and DoD “Displacement on demand”. Although both are great at extending fuel economy… both features add unnecessary weight and complexity to the LT4 valve train, which is why they are so commonly deleted during a standard head and cam package upgrade.
Although there are a few other ways to get this done, we feel that the Katech solutions are by far the most elegant, well engineered, best fitting and durable. Which is why they were used on our own shop car build found HERE.
Katech Gen. 5 LT VVT-Delete Billet Front Cover Kit - Wet Sump #KAT-A6914
The Katech VVT Delete front cover eliminates the heavy VVT cam phaser which can become problematic when installing an aftermarket cam kit. Designed for use with single bolt camshafts, the front cover includes a new 1 bolt sprocket, front main seal and cam bolt.
The first thing you will notice when you open the package is the extreme attention to detail found in the billet machining. Katech went to great lengths to make design this cover to look as well as it performs. Black anodized and made of billet aluminum in the USA by Katech.
NOTE: Customers installing this front cover on L82/L84 applications without the oil pump solenoid will need to plug the hole for the solenoid wiring passthrough. We recommend a Dorman 555-101 expansion plug with epoxy around the circumference of the plug, and staking the hole from the inside to lock in the plug.
Katech Gen. 5 LT4/LT5 AFM Delete Valley Cover #KAT-A6851
Although there are a few other ways to get this done, we feel that the Katech solutions are by far the most elegant, well engineered, best fitting and durable. Which is why they were used on our own shop car build found HERE.
