Timing Chain Dampener LS2

The Chevrolet Performance Timing Chain Dampener LS2 (part number 12588670) is designed specifically for GM LS-series engines, particularly those equipped with the LS2. This component is essential for managing timing chain oscillation and noise during engine operation, thereby protecting the timing chain assembly from premature wear due to harmonic vibrations at various RPMs. It is particularly beneficial for engine builders and performance technicians working on LS-platform engine swaps or rebuilds.

Constructed from durable plastic, the dampener effectively reduces weight while providing the necessary stiffness to absorb harmonic energy from the timing chain. At idle and low RPM, timing chains can experience lateral movement that accelerates wear on the chain and surrounding components. The LS2 timing chain dampener addresses this issue by limiting oscillation, which extends service life and minimizes noise transmission into the engine bay.

This OEM Chevrolet Performance part is crucial for those performing complete LS engine rebuilds, replacing worn dampeners, or assembling crate engines. Its compatibility with modified LS engines running higher valve springs or aggressive cam profiles makes it a valuable addition for performance enthusiasts. The dampener's design ensures that it maintains the integrity of the timing drive system, making it a reliable choice for any LS2 engine project.
