Cloyes 9-3673TX9ZR Engine Timing Set

Engine Timing Set for Specific Applications

This Cloyes engine timing set is built for specific high-performance applications that require precise cam timing control and durable chain drive components. Part number 9-3673TX9ZR includes a billet crankshaft sprocket with nine keyways for adjustable timing, plus a TRUE Roller Z chain for reduced friction.

Fits 2007-2015 Chevrolet Corvette, N/A. Fits 2007-2015 GMC Sierra 1500, N/A. Fits 2007-2015 Cadillac CTS, N/A. This timing set also fits additional Chevrolet, GMC, Pontiac, Buick, Saab, Hummer, and commercial applications listed in the fitment data.

Key Features

• Billet crankshaft sprocket with 9-keyway adjustability for timing correction
• Heat-treated billet steel sprockets for added durability
• TRUE Roller Z chain with 0.250-inch roller diameter for lower friction
• Press-fit center link design for improved load distribution
• Captured needle camshaft sprocket thrust bearing to reduce thrust surface friction
• Hand-matched 3-piece set to help maintain correct center distance and minimize runout

Detailed Description

Cloyes 9-3673TX9ZR is a specific-fit engine timing set engineered for applications with a .390-inch raised cam, 1-bolt/4-sensor configuration, and race billet requirements. The adjustable billet crankshaft sprocket provides +/- 8 degrees of timing adjustment, while the heat-treated sprockets and Z chain are built for demanding valvetrain use. The chain design increases overall strength compared with standard high-performance chain construction and uses pre-stressed, processed links to improve fatigue life.

For buyers searching for a Chevrolet Corvette timing set, GMC Sierra 1500 timing set, or Cadillac CTS engine timing set, this part number 9-3673TX9ZR matches the listed engine configuration and fitment notes. This part cross-references 93673TX9ZR for the same application.

What It Is Used For

• Correcting cam timing in performance engine builds
• Replacing worn timing components that can affect valve timing accuracy
• Reducing chain friction in high-load valvetrain operation
• Addressing timing instability caused by chain stretch or sprocket wear
• Supporting engines that require adjustable timing setup

Installation Notes and Tips

Verify engine configuration before ordering, including the .390-inch raised cam requirement and the 1-bolt/4-sensor note shown in the fitment data. This is a specific-fit timing set, so confirm application details against the vehicle and engine build. Part number 9-3673TX9ZR should be matched to the exact listed application before installation.

Quality Assurance

Cloyes manufactures timing components for engine valvetrain applications with attention to fit, strength, and dimensional control. The hand-matched set construction and heat-treated sprockets support consistent assembly quality for the specified applications.
