Description

INA ZC0147 Premium Secondary Timing Chain – Ford Falcon XR8 FPV Boss 260 290 5.4L DOHC 32V

The INA ZC0147 Premium Secondary Timing Chain is a high-quality 44-link camshaft timing chain manufactured by INA / Schaeffler, one of the world’s leading manufacturers of OE timing, valvetrain and precision engine components.

This chain is designed for selected Ford 5.4L DOHC 32-Valve 4V Modular V8 engines, with this listing specifically targeted toward Australian Ford Falcon XR8 and FPV Boss 260 / Boss 290 applications.

The chain itself is physically marked INA, providing confidence that the actual component has been manufactured by INA rather than being an unidentified generic chain supplied under an aftermarket brand.

Important – 2 Chains Required Per Engine

The Ford 5.4L DOHC 32V / 4-Valve V8 uses two secondary timing chains.

• 1 x secondary chain per cylinder bank
• 2 x INA ZC0147 chains required per complete engine
• This listing is for 1 x chain unless otherwise stated

For a complete engine timing-system rebuild, order quantity 2.

Secondary Timing Chain Function

The Ford 5.4L DOHC 4-Valve V8 uses a multi-chain timing system operating four camshafts.

The secondary timing chains form part of the camshaft drive system, with one secondary chain used on each cylinder bank.

Maintaining correct secondary-chain dimensions is critical for:

• Accurate camshaft timing
• Consistent valve events
• Stable engine performance
• Reduced timing variation
• Correct relationship between camshafts
• Reduced timing-drive noise
• Consistent performance throughout the RPM range

As the engine uses two cylinder banks, two secondary chains are required for a complete engine.

Why INA Is a Premium Choice

OE-Level Manufacturer

INA is part of the Schaeffler Group, one of the world’s major manufacturers of automotive bearings, timing-drive systems, valvetrain components and precision engine parts.

INA components are widely used in OE and professional automotive applications.

This provides an important advantage over generic aftermarket timing components where the actual chain manufacturer, materials and manufacturing process may not be clearly identified.

---

INA Marked Directly on the Chain

The ZC0147 supplied here is physically marked INA.

This means the engine builder can identify the actual manufacturer of the timing chain rather than relying only on the branding printed on external packaging.

For a critical internal engine component, this provides substantially greater confidence in the part being installed.

---

Reduced Timing-Chain Elongation

Timing-chain “stretch” generally occurs through wear between the chain pins, joints and associated bearing surfaces rather than the steel links simply stretching.

As this wear accumulates, the effective length of the chain increases.

Excessive chain elongation can contribute to:

• Retarded camshaft timing
• Increased timing variation
• Reduced engine performance
• Increased timing-drive noise
• Additional guide wear
• Increased tensioner extension
• Inaccurate camshaft positioning

Premium manufacturing, controlled heat treatment and accurate tolerances help reduce this wear.

---

Ideal for Boss 260 / Boss 290 Engine Rebuilds

The Australian Ford / FPV 5.4L Boss V8 is a relatively complex and increasingly valuable engine.

Timing-chain quality is therefore not an area where we recommend selecting the cheapest available replacement component.

The INA ZC0147 is particularly suitable for:

• Standard Boss engine rebuilds
• Performance engine rebuilds
• Modified Boss 260 engines
• Modified Boss 290 engines
• Cylinder-head rebuilding
• Camshaft upgrades
• Timing-system restoration
• Preventative timing-chain replacement
• Complete engine overhauls

For engine rebuilding, we generally recommend replacing secondary chains as a pair where replacement is required.

Recommended Installation Practice

When rebuilding the timing system on a Ford 5.4L DOHC engine, inspect the complete timing drive and replace components where required, including:

• Primary timing chains
• Secondary timing chains
• Chain guides
• Hydraulic tensioners
• Camshaft sprockets
• Crankshaft sprockets
• Camshaft timing components
• Timing-cover components
• Oil-pump drive components
• Front crankshaft seal

Worn sprockets, guides or tensioners can reduce the service life of a new chain.

Always follow the correct Ford workshop timing procedure before rotating or starting the engine.

---

Important Fitment Information

Ford manufactured multiple versions of the 5.4L Modular V8 with different cylinder heads, sprockets and timing-system configurations.

Before installation, confirm:

• Link count
• Chain pitch
• Chain width
• Sprocket tooth profile
• Chain construction
• Engine model
• Production year
• Original component specifications

This listing is specifically focused toward selected Ford / FPV 5.4L DOHC 32V 4-Valve engines.

It should not be assumed compatible with Ford 5.4L SOHC 2-Valve or 3-Valve engines unless compatibility has been independently confirmed.

Bullet Performance Racing Recommendation

For Ford Falcon XR8, FPV Boss 260 and Boss 290 5.4L DOHC engine builds, timing-chain quality is not an area where we recommend compromising to save a small amount on component cost.

The INA ZC0147 Secondary Timing Chain combines premium construction with the confidence of being manufactured by one of the world’s major OE automotive component suppliers.

With INA identification physically marked on the chain, premium manufacturing quality and excellent resistance to pin and joint wear, it is an excellent choice for professional Ford 5.4L DOHC engine rebuilding.

BPR Chain Quality Rating: 9.5/10

Important: 2 x ZC0147 secondary timing chains are required per complete 5.4L DOHC engine.
