The KUSATEC 3R2Z-6A257-DA Engine Timing Chain Kit is a complete, direct-fit replacement set for Ford/Lincoln 5.4L SOHC engines that restores timing components to factory-style specifications.

This kit from KUSATEC bundles all major front-end timing parts needed when replacing worn chains, tensioners, phasers, guides and related seals on 5.4L SOHC V8 engines. Designed as an OE-spec service kit and fully tested before shipment, it targets Ford Expedition, F-150, F-250, F-350, Lincoln Navigator and Mark LT model years that use the 3R2Z-6A257-DA application. The package consolidates components commonly replaced at the same time to reduce downtime and ensure correct timing-system function after installation.

What parts are included in this KUSATEC timing chain kit?

The kit supplies the primary wear items and hardware needed for a full front-timing overhaul so you don’t have to source parts separately. Components are manufactured to meet OE style and fitment and are inspection-tested prior to shipping.

• 2 camshaft phaser sprockets and 2 phaser bolts
• 2 primary chain tensioners and 2 timing chains
• 1 lower double crankshaft gear and 4 timing chain guides
• 1 front crankshaft seal and front timing cover gasket set

How can this kit help when timing noise or faults appear?

Rattling at the front of the engine, timing-related trouble codes, or visible chain slack usually indicate worn chains, guides, phasers or tensioners. Replacing those components together reduces repeat labor and helps restore consistent valve timing behavior when installed correctly.

• Eliminates common sources of front-end timing noise
• Resolves timing-related ECU fault codes when mechanical cause is replaced
• Reduces risk of future premature wear by renewing guides, chains, and tensioners
• Includes gasket and seal to complete the front cover service in one job

KUSATEC manufactures this kit to OE specifications as a direct-fit aftermarket replacement with factory-style appearance and mounting. Each kit is tested before shipment; materials and design aim to deliver durable service life when installed and torqued per factory procedures.

• Replaces OE number 3R2Z-6A257-DA (also TK-FD019-1-S869)
• Engineered for direct-fit installation matching original mounting points
• Quality-checked components to reduce return rates and installation surprises
