Cloyes VC137 Engine Variable Valve Timing (VVT) Sprocket - Intake

Engine VVT Sprocket Overview

The Cloyes VC137 is an engine variable valve timing sprocket for intake-side applications on select Chrysler, Dodge, and Jeep vehicles. It is built as a camshaft phaser replacement for higher-mileage engines where timing control, phaser function, and consistent valve timing matter.

Key Features

• Variable valve timing sprocket design for intake camshaft control
• Premium-material construction with function, fitment, and durability testing
• Verified for adjustable angle, leakage, locking pin function, and friction
• Includes new torque-to-yield attachment bolts and valving bolts
• Two timing marks for installation reference
• Part number VC137 for ordering and catalog matching

Detailed Description

The Cloyes VC137 VVT sprocket is engineered for intake camshaft timing service on compatible Chrysler 200, Dodge Journey, Dodge Avenger, Dodge Caliber, Jeep Compass, Jeep Patriot, and Chrysler Sebring applications. This VC137 cam phaser replacement is manufactured and measured to support proper fitment and stable operation, with testing focused on angle adjustment, sealing performance, locking pin operation, and friction control. Cloyes VC137 is a practical choice when servicing the timing system on vehicles that rely on precise variable valve timing.

Cloyes recommends replacing the timing chain, tensioners, sprockets, and guides at the same time as VVT components to help maintain timing system stability. This part cross-references 05047021AB for the same application.

Common Repair Uses

• Restores intake camshaft timing control when the original phaser is worn
• Addresses timing noise or irregular valve timing behavior
• Helps correct leakage or locking pin function concerns in the VVT system
• Supports repair of high-mileage timing system wear
• Replaces a damaged or out-of-spec VVT sprocket

Installation Notes

Install on the intake side only for the listed applications. Follow factory timing procedures and verify camshaft alignment during installation. Cloyes includes new torque-to-yield attachment bolts and valving bolts for proper phaser installation and function. For best results, inspect the timing chain, tensioners, sprockets, and guides during service and replace worn components as needed.
