DJ Rock TK4198 Engine Timing Set

Engine Timing Set Overview

DJ Rock TK4198 is a premium engine timing set built to synchronize crankshaft and camshaft movement for accurate valve operation. It is a fitment-based replacement for select Ford, Lincoln, Mazda, and Mercury applications, including Ford Flex, Ford Taurus, and Mazda CX-9 models.

Key Features

• Single roller timing chain design for controlled chain engagement.
• Steel camshaft and crankshaft sprockets for strength and accurate tooth engagement.
• Timing marks included to support correct component alignment during service.
• Premium-grade construction built to meet or exceed OEM quality standards.
• Designed for applications that require a timing set with sprockets.

Detailed Description

The TK4198 timing set is engineered for engine service where precise cam-to-crank synchronization is critical. DNJ timing chain kit construction uses heavy-duty steel chain materials, hardened alloy steel sprockets, and wear-resistant components selected for durability under thermal and mechanical load. This makes it a practical choice for timing service on Ford Taurus, Lincoln MKS, and Mazda 6 applications listed in the fitment data. Part number TK4198 is also referenced as 3-1047S for the same application.

Depending on the vehicle configuration, the listed fitments include premium kit variants with or without gears and primary tensioner requirements. Confirm the exact engine configuration and notes before ordering, especially for 2010-2011 Ford and Mazda applications with 202-link lower primary chain requirements.

Common Issues This Part May Address

• Excessive timing chain stretch.
• Worn or noisy chain guides and sprockets.
• Incorrect valve timing from aged timing components.
• Service needs after timing system wear or teardown.
• Loss of synchronization between crankshaft and camshaft.

Installation Notes and Tips

Verify the engine code, timing configuration, and fitment notes before installation. This set is listed for applications with roller-type primary chain requirements and, in some cases, without VVT cam gears or without a primary tensioner. Use the timing marks during assembly and follow the service procedure for the specific vehicle to maintain correct valve timing.

Quality Assurance

DNJ timing chain kits are manufactured to exact tolerances and built to meet or exceed OEM quality standards. The TK4198 uses premium materials and precision-machined sprockets to support long service life in demanding engine applications.
