DJ Rock TK4170 Engine Timing Set

Engine Timing Set Overview

This engine timing set is built for Ford applications that require accurate crankshaft and camshaft synchronization. The TK4170 uses a silent timing chain design with steel sprockets and timing marks to support precise valve timing in demanding service.

Key Features

• Silent timing chain design for smoother operation.
• Steel camshaft sprocket and crankshaft sprocket construction.
• Timing marks included for accurate alignment during service.
• Premium-grade kit built to meet or exceed OEM quality standards.
• Sprockets included for a complete timing service solution.

Detailed Description

The DJ Rock TK4170 engine timing set is engineered for Ford E-150, E-250, E-350 Super Duty, E-450 Super Duty, Excursion, Expedition, F-150, F-150 Heritage, F-250 Super Duty, and F-350 Super Duty applications listed in the fitment data. It is also a fit for Ford E-150 Econoline, E-150 Econoline Club Wagon, E-250 Econoline, E-350 Econoline Club Wagon, and E-450 Econoline Super Duty models shown below. This timing set is intended to restore proper synchronization between the crankshaft and camshaft, which is critical for accurate valve operation and consistent engine timing. The TK4170 part number is useful when matching the correct timing kit for Ford truck and van service, and the TK4170 reference also aligns with Cloyes 9-0391SB for the same application.

What It Helps Address

• Timing chain stretch that can affect camshaft and crankshaft synchronization.
• Worn sprocket engagement that can lead to timing instability.
• Incorrect valve timing caused by degraded timing components.
• Noise from worn timing components in the valve train.
• Service replacement needs on Ford engine timing systems.

Installation Notes and Tips

Verify engine code, timing marks, and cam gear configuration before installation. Follow factory service procedures for alignment and torque specifications to ensure correct timing set-up. Confirm the application against the TK4170 part number and the vehicle fitment notes before ordering.
