Product Information

An engine timing chain is a crucial component in an internal combustion engine that synchronizes the rotation of the crankshaft and camshafts. It ensures that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes, maintaining optimal engine performance. Timing chains are typically made of metal and are designed to last for the life of the engine, though they can wear out or become damaged over time. Damaged or stretched chains can impact the timing on an engine and overwork the tensioner, failures in this system can cause catastrophic engine failure and costly repairs.

• Noise: A common symptom of a failing timing chain is a rattling or slapping noise coming from the engine, especially during startup or acceleration. This noise may be more pronounced at idle or startup
• Poor Engine Performance: If the timing chain is stretched, it can lead to decreased power, acceleration problems, or sluggish performance

About Iwis

Iwis was founded in 1916 by Bavarian businessman Johann Baptist to manufacture chains for two-wheeled vehicles, but by 1939 Iwis was making the precision chain solutions for engine and drive systems for companies like BMW and Skoda. Today Iwis is headquareted out of Munich, Germany with a workforce over 1150. The Iwis goal is "100% repeatability across 30 million parts manufactured each day" meaning their manufacturing process goal is perfection across every link they manufacture, be it the first or 30,000,000th link. With attention to detail like that it is no wonder Iwis is a worldwide leader in high-quality chain solutions.
