INA ZC-9-4221 Engine Timing Chain

INA ZC-9-4221 Timing Chain for Toyota 2TR-FE

INA ZC-9-4221 is an engine timing chain built for Toyota applications using the 2TR-FE engine. This roller chain uses 124 links and is manufactured with heat-treated plates and pins to support consistent timing performance and durability.

Key Features

• Engine timing chain for valve train service
• Roller chain design with 124 links
• Heat-treated plates and pins for controlled hardness
• OE-quality replacement from INA
• Cross-reference: 5530510100

Product Details

This INA timing chain, part number ZC-9-4221, is made for Toyota Tacoma and Toyota 4Runner models equipped with the 2TR-FE engine. It is a primary timing chain application for 2005-2020 Toyota Tacoma and a primary timing chain application for the 2010 Toyota 4Runner. The roller chain construction and 124-link count are important specifications for matching the original engine timing setup.

INA timing chains are engineered to meet or exceed OE quality and performance expectations, with chain plates and pins heat treated to precise hardness levels. That focus on material control helps maintain timing accuracy in demanding engine service conditions. If you are replacing a worn Toyota Tacoma timing chain or servicing a 2TR-FE timing drive in a Toyota 4Runner, ZC-9-4221 provides the correct chain specification for the listed applications.

Common Uses

• Replacing a stretched or worn timing chain
• Addressing engine timing noise from chain wear
• Restoring camshaft and crankshaft synchronization
• Correcting timing-related drivability or fault-code concerns
• Servicing the primary timing drive on 2TR-FE engines

Installation Notes

Verify engine code, chain type, and link count before installation. This part is listed for primary timing chain applications on 2005-2020 Toyota Tacoma and 2010 Toyota 4Runner models with the 2TR-FE engine. Follow factory service procedures, inspect related timing components during service, and confirm proper timing alignment during assembly.

Quality Assurance

INA manufactures this timing chain to OE-quality standards using heat-treated chain components for durability and performance consistency. Part number ZC-9-4221 also cross-references 5530510100 for the same application.
