### Product Details

Engine Timing Set (9-3512X9) by Cloyes®. Keep your engine’s valvetrain in perfect time with Cloyes, the world leader in timing drive systems. No matter whether you need a timing gear or complete timing gear set, Cloyes has the OE quality parts that will fit right and deliver optimal performance. Sprockets are made from high alloy steel, and heat-treated for durability. Chain is pre-stressed and heat-treated for longevity.

The crankshaft drives the valvetrain via timing gears. Gear timing must be precise to ensure the valves open and close at the right time, for optimum engine performance. However, worn gears can cause timing to go astray and cause the engine to not start or run poorly. When it’s time to replace worn timing system components, depend on Cloyes for the OE quality timing drive components that will restore engine performance and reliability. Cloyes has been manufacturing timing components for over 80 years. It’s their only product line, which enables them to concentrate on maintaining the highest quality standards. In fact, Cloyes has achieved ISO/TS 16949 quality certification, the highest level offered for the design/development and production of automotive related products. Cloyes is the only aftermarket timing component manufacturer that is also a Tier 1 supplier to OE vehicle manufacturers.
