Melling 5.4L V8 Upgraded Timing Chain Tensioners & Dampers – BA BF FG Falcon XR8 / FPV Boss 260 Boss 290

Premium Melling timing chain tensioners and dampers to suit Ford Australia 5.4L DOHC Boss V8 engines, including Boss 260 and Boss 290 applications.

These Melling components feature a high-quality cast-metal OEM-style construction that closely matches the design, finish and operation of the original Ford factory timing components. The overall quality of manufacture makes them an excellent choice for customers wanting an OEM-style replacement for worn or ageing factory timing-chain components.

Designed for timing-system servicing, engine rebuilds and performance engine preparation, this kit helps maintain correct primary timing-chain tension and control while reducing excessive chain movement and timing noise.

Why Replace the Timing Components?

Age, mileage and repeated heat cycles can cause original timing-chain tensioners, guides and dampers to wear or lose effectiveness. This may result in excessive chain movement, timing noise and reduced control of the camshaft drive system.

Replacing worn timing components during an engine rebuild or major service helps restore correct timing-chain control and improves long-term reliability.

Recommended During Installation

We recommend inspecting or replacing the following components at the same time:

• Primary timing chains
• Secondary timing chains
• Chain guides and dampers
• Camshaft sprockets
• Crankshaft sprocket
• Oil pump and oil-pump drive components
• Front timing-cover seals and gaskets

Important Fitment Notice

Ford used several timing-component revisions across different 5.4L Modular V8 applications.

Please confirm the existing timing configuration and engine application before ordering.
