Detailed Description

Melling timing chain kits are offered as a service-focused solution for engine timing repair and rebuild work. Part number 3-4SR50SA uses a single roller chain and steel sprockets to provide the timing components needed for stock-level engine service. This kit is part of Melling’s standard replacement line, which is aimed at applications that call for OE-style timing components rather than performance changes.

Fitment includes 1996-1999 Chevrolet C2500, C2500 Suburban, C3500, Express 3500, K2500, K2500 Suburban, K3500, and P30, plus 1996-1999 GMC C2500, C2500 Suburban, C3500, K2500, K2500 Suburban, K3500, P3500, and Savana 3500. For Chevrolet C2500 and GMC K3500 rebuilds, this timing set provides the matched chain-and-sprocket components needed to restore proper engine timing. The 3-4SR50SA is also cross-referenced to Cloyes C-3213 and Dayco 73136, 73137 for the same application.

What It Is Used For

• Replacing worn timing chain components during an engine rebuild
• Restoring correct camshaft-to-crankshaft timing
• Addressing chain stretch, sprocket wear, or timing noise
• Servicing stock engine configurations in Chevrolet and GMC applications
• Updating timing components with a standard replacement kit

Installation Notes and Tips

Verify engine code and application details before installation, since timing sets are engine-specific. Inspect related timing components, including guides and tensioners where applicable, and confirm sprocket alignment during assembly. Follow factory service procedures for timing marks, chain routing, and torque specifications.
