The Cloyes 9-3172A engine timing set is built for performance-focused valve timing control in select 2006-2007 Cadillac CTS and 2006 Chevrolet Corvette applications. It uses a HEX-A-JUST adjustable cam sprocket design to fine-tune cam timing by up to 6 degrees advance or retard for engine setup and output optimization.

Key Features

• HEX-A-JUST adjustable cam timing with +/-6 degrees at the camshaft
• One-piece camshaft sprocket with billet eccentric camshaft dowel bushing
• Heat-treated billet steel camshaft and crankshaft sprockets
• True roller single roller chain with 0.250-inch roller diameter for reduced friction
• Captured needle camshaft sprocket thrust bearing to reduce friction
• Hand-matched set for correct center distance and reduced runout
• Steel sprockets and performance-grade construction

The 9-3172A is a direct-fit timing set for 2006-2007 Cadillac CTS and 2006 Chevrolet Corvette applications listed with a 3-bolt, 4-sensor hub and HEX-A-JUST configuration. This part number, 9-3172A, is also referenced as 93172A.

What It Helps Address

• Cam timing that needs advance or retard adjustment during engine tuning
• Timing chain friction in performance engine builds
• Runout concerns from mismatched timing components
• Wear concerns in high-load valve train operation
• Fitment needs for 2006 Cadillac Corvette and 2006-2007 Cadillac CTS timing set applications

Installation Notes and Tips

Verify engine configuration, hub style, and sensor setup before installation. The timing set is listed for 2006-2007 Cadillac CTS and 2006 Chevrolet Corvette applications with a 3-bolt, 4-sensor hub and HEX-A-JUST setup. Follow factory service procedures for cam timing alignment, chain indexing, and torque specifications. Because this is an adjustable performance timing set, final cam timing should be checked during assembly and confirmed with the engine combination in use.
