LS1 MTR MOUNT CLAMSHELL INSERT

The LS1 MTR Mount Clamshell Insert from Energy Suspension is a precision-engineered component designed for LS1-equipped vehicles undergoing performance modifications or restoration work. This insert addresses vibration isolation and powertrain mounting challenges that are common in high-displacement, high-revving LS1 engine swaps and upgraded applications. It is suitable for builders looking to enhance their engine mounts without the need for extensive modifications.

The clamshell insert design fits within factory motor mount brackets, providing a straightforward replacement for worn or damaged OEM rubber isolators. Its engineered elastomer compound balances compliance and stiffness, helping to maintain driveline integrity while dampening vibration peaks typical of aggressive cam profiles and forced induction setups. The insert is designed for easy installation without the need for full engine removal.

This mount insert is ideal for LS1 engine swap applications, including fourth-generation Camaro and Firebird platform conversions, truck-based LS1 projects, and standalone crate engine builds. By restoring proper engine geometry and reducing transmitted noise, vibration, and harshness (NVH), it enhances the overall driving experience for performance enthusiasts.
