Timing Chain Dampener LS2

The Chevrolet Performance Timing Chain Dampener LS2 (part number 12588670) is a factory-engineered plastic dampener engineered specifically for GM LS-series engines, particularly LS2-equipped vehicles. This component manages timing chain oscillation and noise during engine operation, protecting the critical timing chain assembly from premature wear caused by harmonic vibration at varying RPM ranges.

The dampener's plastic construction reduces weight while maintaining the stiffness required to absorb harmonic energy from the timing chain. At idle and low RPM, timing chains experience lateral movement that can accelerate wear on the chain itself and surrounding components. The LS2 timing chain dampener addresses this by limiting that oscillation, extending service life and reducing noise transmission into the engine bay. Proper dampener function becomes increasingly important in modified LS engines running higher valve springs or aggressive cam profiles, where chain movement increases substantially.

This OEM Chevrolet Performance part is essential for LS2 engine builders, performance technicians, and LS-platform engine swap builders who require factory-specification timing components. Whether performing a complete LS engine rebuild, replacing a worn original dampener, or assembling a crate engine installation, this timing chain dampener maintains the integrity of the timing drive system. The black finish matches other LS engine bay components. Weighing just 0.21 lbs, it installs quickly without tools and is a straightforward replacement during timing cover service.
