Timing Chain Kit Overview

The Gates CHK203 timing chain component kit is built for engine timing service where OE-level function and fit matter. It is a fitment-based replacement for a wide range of Chevrolet, GMC, Cadillac, Buick, Oldsmobile, and Pontiac applications, including Chevrolet Express 1500 timing chain kit and GMC Savana 2500 timing chain kit use cases.

Gates CHK203 is part of the Timing Chain Component Kits line, which focuses on timing drive service parts for replacement applications. This kit uses a steel silent chain with steel sprockets for a durable timing drive layout.

Key Features

Steel timing chain construction for strength in engine timing service.
Silent chain design for smooth timing drive operation.
Steel camshaft sprocket material for matched component durability.
Drive sprocket included for a complete timing drive service package.
Fits a broad range of GM trucks, vans, SUVs, and passenger cars.

Detailed Description

The Gates CHK203 engine timing chain kit is engineered for direct replacement service in applications that require a timing chain, sprocket set, and OE-style fit. The chain uses a 12.7 mm pitch and 46 pins, with a 0.61 in. chain width, supporting consistent timing drive engagement. Gates draws on its timing drive systems experience in both original equipment and aftermarket markets, and this kit is built to meet or exceed OE standards in function, fit, and performance. This part cross-references Cloyes C-3017 and SKF VKML71007A for the same application.

What It Helps Fix

Excessive timing chain stretch.
Timing noise from worn chain components.
Loss of camshaft timing accuracy.
Wear in the timing drive sprocket set.
Service needs on high-mileage GM engines.

Installation Notes

Verify engine code and application details before ordering, since this kit fits multiple GM platforms across several model years. Confirm that the existing service setup matches the included timing chain and sprocket configuration. Professional installation is recommended for timing system service because correct cam timing is critical to engine operation.

Quality Assurance

Gates builds timing drive components for original equipment and replacement markets, and the CHK203 is manufactured to meet or exceed OE standards in function, fit, and performance.

This part fits 193 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
