These mounts are designed to mount an LS Series Engine where an early 3 Bolt motor was previously installed. The large Metal Plates bolt to the LS engine and allow for the typical 3 bolt mount to connect to your new LS engine. The 3 Bolt Mount that connects to the adapter plate will then connect to your OEM frame side mounts.

In order to determine which set you need you will simply measure your frame side bracket.

Energy Suspension Motor Mounts

If they haven't already, rubber factory mounts on your ride will soon wear out and tear away from their mounting brackets and create a big problem. Once this happens, you can expect a lot of rocking to be coming from your motor and a lot of dangerous engine movement. The cure: Energy Suspension's Hyperflex Motor Mounts. With Energy Suspension's polyurethane motor mounts, you can provide firm support for your engine, while still enjoying the benefits of a smooth ride.

Stronger Polyurethane Mounts

Energy Suspension manufactures these mounts to limit unwanted movement of the motor. With these new polyurethane mounts installed, you can achieve more power to the wheels with an almost indestructible mount, gaining an edge on the street or on the track. Energy Suspension's mounts are very durable and are resistant to oil, chemicals and other road contaminants that would normally deteriorate a rubber mount. These mounts are engineered specifically for each vehicle, matching OE specifications and adding performance. Also, where applicable, most of the mounts feature a "Polylocked Run-Safe" interlocking design that allows the mounts to have interlocking steel inserts to add to the durability and performance.
