Gates CHK131 Engine Timing Chain Kit

Timing Chain Kit Overview

Gates CHK131 is an engine timing chain kit built for interference-engine applications that require precise valve timing and durable chain-drive components. It is a fitment-based replacement for select Toyota trucks and SUVs, including Toyota 4Runner, Toyota FJ Cruiser, and Toyota Tundra applications.

Key Features

• Steel roller timing chain construction for consistent chain drive operation.
• Includes chain guides, tensioners, and drive sprockets for a complete timing service.
• Camshaft sprocket material is steel for added durability in the valvetrain.
• Built to meet or exceed OE standards in function, fit, and performance.
• Gates CHK131 supports timing service on select Toyota 4Runner, FJ Cruiser, and Tundra engines.

Detailed Description

The Gates Timing Chain Component Kits line draws on Gates’ experience in original equipment and aftermarket timing drive systems. CHK131 is engineered as a component kit for engine timing service, combining steel chains with matched guides, tensioners, and sprockets to restore proper chain control and timing accuracy. This part cross-references Cloyes 9-0924S and 90924SX for the same application.

For fitment-focused searches, this kit fits 2010-2021 Toyota 4Runner, 2010-2014 Toyota FJ Cruiser, and 2012-2014 Toyota Tundra applications. It also fits 2011 Toyota Tundra, Oct. 2010 & newer, for the listed interference-engine application. CHK131 is a practical choice when the timing drive shows wear, noise, or timing-related drivability concerns.

What It Is Used For

• Timing chain stretch that affects camshaft and crankshaft synchronization.
• Worn guides that can create chain noise or unstable chain tracking.
• Weak tensioners that allow slack in the timing drive.
• Damaged sprockets that can disrupt timing accuracy.
• Timing service on interference engines where precise valve timing matters.

Installation Notes and Tips

Confirm engine code and application details before ordering, especially for the 2011 Toyota Tundra Oct. 2010 & newer listing. Replace related timing components together when wear is present so the new chain system operates as a matched assembly. Follow factory timing marks and service procedures during installation.

Quality Assurance

Gates is a global supplier of timing drive systems in both OE and replacement markets. CHK131 is backed by Gates’ OE-focused engineering approach and is built to meet or exceed OE standards in function, fit, and performance.
