The kit uses a single roller chain with timing marks and steel sprocket construction to support accurate cam and crank synchronization during engine service. Melling also designs its timing components and oil pumps to production standards, making this kit a practical choice for engine rebuilds where dependable timing hardware is required. Part number TOPK-1017 is listed for multiple Buick, Chevrolet, and GMC models across 2009-2017 coverage, including Chevrolet Malibu, Chevrolet Impala, and Buick LaCrosse applications.

What It Is Used For

• Replacing worn timing chain components during engine rebuilds

• Addressing timing noise caused by aged chain and gear components
• Refreshing matched timing hardware when service marks are needed for setup
• Supporting repair work on Buick, Chevrolet, and GMC engines with stock-style parts

Installation Notes and Tips

Verify engine code and application details before ordering, since fitment varies by model and year. This kit is listed with a note that the S911 water pump sprocket is not included and must be ordered separately as needed. Follow factory timing procedures carefully and confirm all timing marks before engine start-up. TOPK-1017 is also referenced for Chevrolet HHR, Chevrolet Cobalt, and Pontiac G5 applications.

Quality Assurance

Melling manufactures timing components using quality materials and workmanship, and its oil pumps are individually tested for pressure and flow under conditions that duplicate engine operating conditions. Part number TOPK-1017 reflects that same production-focused approach for stock replacement engine service.
