Standard Ignition VVT537 Engine Variable Valve Timing (VVT) Sprocket - Intake

Standard Ignition VVT537 Engine Variable Valve Timing Sprocket

Standard Ignition VVT537 is an engine variable valve timing sprocket built for the intake side on select Nissan Sentra applications. It uses a metal gear construction with a single-row design and three timing marks for accurate cam timing reference during service.

Key Features

• Engine variable valve timing sprocket for intake applications
• Metal gear material for durable valve train service
• 42 teeth with one gear and one row
• Three timing marks for alignment reference
• 1.42 in. inside diameter and 3.24 in. outside diameter
• Crankshaft gear type with one mounting hole
• No adjustable mechanism and no hardware included

Product Details

This Standard Ignition VVT537 sprocket is built to restore proper variable valve timing function in the valve train. It is a direct-fit intake sprocket for 2003-2006 Nissan Sentra models and is sized with an 8.128 mm thickness, 9.906 mm lug hole diameter, and 36.068 mm inside diameter. The 42-tooth metal gear design and timing marks support accurate positioning during replacement of a worn or damaged VVT sprocket. This part cross-references ECP1739 and VV5037 for the same application.

Common Problems It Can Address

• Rattling or worn sprocket components in the valve train
• Incorrect cam timing caused by a damaged VVT sprocket
• Check engine light concerns related to variable valve timing operation
• Rough idle or drivability issues tied to timing control
• Timing mark alignment problems during engine service

Installation Notes and Tips

Fits 2003-2006 Nissan Sentra, intake. Verify tooth count, inside diameter, and timing mark layout before installation. Clean the mating surfaces, follow factory timing procedures, and confirm cam timing after the sprocket is installed. Because this is a valve train timing component, precise alignment is important for proper engine operation.

Quality Assurance

Standard Ignition supplies replacement engine management and valve train components for service applications. VVT537 is built to match the listed fitment and dimensional specifications for the intended Nissan Sentra intake application.
