Cloyes 9-3110A Engine Timing Set

Engine Timing Set Overview

The Cloyes 9-3110A engine timing set is built for applications that use a non-factory roller cam engine with Hex-A-Just adjustment. It provides timing control for a wide range of Chevrolet and GMC V8 applications, including classic and heavy-duty platforms.

For buyers searching for a Chevrolet Camaro engine timing set or a GMC C2500 timing set, this part number 9-3110A offers adjustable cam timing and roller-chain construction in one package.

Key Features

• HEX-A-JUST design provides infinite valve timing adjustment within +/-6 degrees.
• One-piece camshaft sprocket uses a billet eccentric camshaft dowel bushing.
• Heat-treated billet steel sprockets add durability under engine load.
• TRUE Roller chain with a 0.250-inch roller diameter reduces friction.
• Captured needle camshaft sprocket thrust bearing helps reduce block thrust surface friction.
• Hand-matched set helps qualify center distance and minimize runout.

Detailed Description

This Cloyes timing set is intended for performance and service applications where precise cam timing adjustment matters. The 9-3110A combines adjustable sprockets, a roller chain, and a thrust-bearing design to support accurate timing control and smoother operation. It is listed for a broad range of Chevrolet and GMC models, including Chevrolet Camaro, Chevrolet Corvette, GMC C2500, and Chevrolet C10 applications with the specified engine setup.

The product line centers on adjustable timing components for builders who need more control than a fixed-index set provides. If you are replacing or upgrading a timing set on a compatible Chevrolet or GMC engine, part number 9-3110A is built around durability, reduced friction, and repeatable alignment.

This part cross-references Monroe Shocks & Struts (e.g., 93110A) for the same application.

What It Is Used For

• Correcting cam timing during engine assembly or rebuild
• Fine-tuning valve timing for performance calibration
• Replacing worn timing components that can affect chain control
• Reducing friction in roller-cam timing systems
• Supporting stable timing alignment in high-use engines

Installation Notes and Tips

Install only on non-factory roller cam engines with Hex-A-Just and standard duty engine timing set requirements. Verify camshaft, sprocket, and chain alignment before final assembly, and confirm the engine configuration matches the listed fitment for Chevrolet and GMC applications. Part number 9-3110A should be checked against the existing timing cover and camshaft setup before installation.

Quality Assurance

Cloyes designs this timing set with heat-treated billet steel sprockets, a captured needle thrust bearing, and hand-matched components to support consistent fit and reduced runout. The included thrust bearing is listed in the product attributes.
