Good To Know

Q: Why do some LS engine blocks require a drilling template for the tensioner? A: Many early Gen III blocks were not drilled or tapped from the factory for a timing chain dampener, requiring modification to add one.

Q: What drill bit size should be used with this template? A: You should use the drill bit size specified by your timing chain dampener manufacturer, typically matched to an M8 tap.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
