Jaguar TCK Bulletin

FAI have issued a technical bulletin for our TCK89 (Jaguar AJV8 Models) due to a number of customer queries regarding the construction of the tensioner. The AJ-V8 engine was originally fitted with plastic chain tensioners which were prone to fractures.

To combat the original design flaw, Jaguar manufactured the tensioner with a metal construction from 2005. As we follow OE specification, our kits also contain the metal chain tensioners.
