• Standard replacement grade for rebuild and service work
• Made in the USA with individually tested oil pump performance

Detailed Description

TOPK-1000HV is a Melling engine timing set engineered for applications that use variable valve timing components and a stock-style replacement layout. The kit is designed around a roller chain and steel sprockets, with the timing marks needed for accurate installation. Melling also includes an oil pump in this product line, giving rebuilders a practical way to refresh the timing drive and oiling system at the same time. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with Chevrolet Express 2500, Silverado 2500 HD, Silverado 3500 HD, Suburban 3500 HD, and other listed Chevrolet and GMC applications, TOPK-1000HV is a fitment-based solution for stock engine service. It is also listed for Chevrolet Tahoe, GMC Yukon, and GMC Sierra 1500 applications in the specified years. Use TOPK-1000HV when replacing worn timing components on supported Chevrolet Silverado and GMC Sierra engines.

What It Is Used For

• Replacing stretched or worn timing chain components
• Restoring camshaft and crankshaft synchronization
• Addressing timing noise from worn chain or sprocket wear
• Refreshing the oil pump during an engine rebuild
• Servicing stock VVT-equipped GM truck and van engines

Installation Notes and Tips

Verify engine code, VVT configuration, and the exact model-year listing before installation. Confirm sprocket alignment with the timing marks during assembly, and inspect related guides, tensioners, and oiling components for wear while the front cover is open. Professional installation is recommended for engine timing service.

Quality Assurance

Melling manufactures this timing set in the USA and tests each oil pump for pressure and flow under conditions that simulate actual engine operation. The components are built to standard replacement specifications for rebuild work.
