Detailed Description

Cloyes 9-4311S is an engine timing chain kit for front-mounted timing service on select Buick and Chevrolet models. It is engineered around the timing drive system requirements of the application and uses a roller chain with a steel crankshaft sprocket for consistent engagement and durability. This kit is listed for 2020-2021 Buick Encore and 2020-2021 Chevrolet Trax, as well as earlier front timing applications including Chevrolet Sonic, Chevrolet Cruze, Chevrolet Cruze Limited, Chevrolet Volt, and Cadillac ELR. For fitment-specific service, note that some applications require separate VVT sprockets and camshaft sprockets, which are excluded from this kit.

Installation Notes

Confirm engine code, timing cover configuration, and OE component requirements before installation. Because this kit excludes VVT sprockets and camshaft sprockets on listed front applications, compare the existing timing system to the service parts needed for the repair. Proper cam and crank timing alignment is critical during installation, especially on Chevrolet Cruze, Chevrolet Sonic, and Buick Encore timing chain service.
