    Fits LS2 LS3 L99 LS4 LSA LC9 L92 L96 LY6 L94 L9H L76 L77 | Replaces GM 12588670 | Chain Stabilizer Upgrade

    Improve timing stability and extend timing chain life with the Michigan Motorsports LS2 Timing Chain Dampener. This LS2-style dampener is engineered to reduce chain whip and minimize timing fluctuations, helping maintain consistent valve timing under both daily driving and performance conditions. Designed as a direct replacement for GM part number 12588670, this dampener is also a popular upgrade for replacing the failure-prone spring-style tensioners found on many 2007+ LS engines. Whether you're refreshing a high-mileage engine or upgrading your valvetrain, this bolt-in dampener provides improved reliability and peace of mind for your LS build.

    Key Features & Benefits

    • Reduces Timing Chain Whip: Helps stabilize the timing chain to reduce slack, improve timing accuracy, and extend chain life.

      Nice part! If it helps save C5-R chain life with the new REDHOT cam and chain sprocket well buy in!
