KUSATEC Timing Chain Kit 3R2Z-6A257-DA for 5.4L SOHC Ford V8 — Complete OE-spec Kit

The KUSATEC 3R2Z-6A257-DA Engine Timing Chain Kit is a complete, OE-spec replacement set designed to restore timing system performance on 5.4L SOHC Ford V8 engines.

When timing chains, guides, phasers or tensioners show wear, engine noise, or timing-related fault codes, replacing the whole timing assembly with a matched kit eliminates guesswork and prevents premature failures. This KUSATEC kit includes sprockets, chains, guides, tensioners and seals manufactured to fit the Ford 5.4L SOHC applications listed, providing a direct-fit solution for technicians and DIY mechanics who need a durable, tested replacement.

• 2 primary chain tensioners and 2 timing chains
• 1 lower double crankshaft gear and 4 timing chain guides
• Front crankshaft seal and front timing cover gasket set included

How does this kit compare to the original equipment (OE) parts?

KUSATEC engineered this kit to OE specifications to ensure fit, form and function match factory components. Each kit is inspected prior to shipping so it arrives ready for direct installation, reducing installation time and alignment issues.

• Replaces OE part numbers including 3R2Z-6A257-DA and TK-FD019-1-S869
• Manufactured to factory tolerances for direct-fit installation
• Each kit is tested before shipment for quality assurance

When should I consider replacing the timing chain components?

Replace the timing chain kit if you experience front-end rattles, noisy timing chains, or timing-related diagnostic trouble codes (DTCs). Proactive replacement during major service prevents collateral damage to the engine and avoids repeat labor.

• Loud or irregular rattling from the timing cover area
• Persistent timing-related ECU fault codes after diagnosis
• Visible chain slack, worn guides, or failed tensioners on inspection

Who is this for: The KUSATEC 3R2Z-6A257-DA Engine Timing Chain Kit is aimed at vehicle owners, fleet managers and professional technicians working on Ford 5.4L SOHC V8 engines who want a full, OE-spec replacement. It’s ideal when you need a single-purchase solution that covers all timing system wear components—especially during engine noise diagnosis, timing repairs, or preventive maintenance. Always confirm VIN and engine details before ordering to ensure fitment.
