One of the biggest areas of unwanted movement in the Pontiac G8 and Chevy SS rear suspension comes from the factory-mounted rear cradle. Under hard acceleration, aggressive cornering, and rapid weight transfer, movement within the factory cradle bushings can allow the entire rear suspension assembly to shift rather than immediately transferring that energy into the tires.

The Street Slayer Cradle Lock-Out Kit was developed to address that movement while avoiding one of the biggest compromises associated with traditional solid cradle bushings: increased noise, vibration, and harshness (NVH).

Rather than replacing the factory mounting system with a completely solid connection, these lock-outs use a specially developed proprietary polyurethane blend to control and significantly reduce cradle movement. The material provides the rigidity needed for performance driving while retaining enough compliance to keep the vehicle comfortable and enjoyable on the street.

Put the Power Where It Belongs

During a hard launch, minimizing movement between the chassis and rear cradle allows the suspension to react more consistently and helps transfer power more effectively to the rear tires.

For drag-oriented G8 and SS builds, that can mean more predictable launches and improved 60-foot consistency. On the street or through the corners, reducing cradle movement creates a more connected feeling between the chassis and rear suspension, improving responsiveness and driver confidence.

The benefits aren’t limited to dedicated race cars. Even mildly modified street cars can benefit from a rear cradle that remains more securely located during acceleration, braking, and cornering.

Performance Without the Solid-Bushing Compromise

Solid cradle bushings can provide excellent control, but that additional rigidity can also transfer significantly more drivetrain and road noise into the chassis.

The Street Slayer Cradle Lock-Out Kit was developed specifically to bridge that gap.

After extensive testing and development, the proprietary poly blend provides the additional cradle support demanded by performance enthusiasts without completely eliminating the isolation that makes the G8 and SS such capable street cars.

The result is a rear suspension that feels tighter, more planted, and more responsive without unnecessarily sacrificing everyday drivability.

Whether you’re trying to improve your 60-foot at the drag strip, put down more power on the street, or simply eliminate unwanted movement from the rear suspension, the Street Slayer Cradle Lock-Out Kit provides a purpose-built solution for the Pontiac G8 and Chevy SS.

Lock down the cradle. Put the power to the pavement. Keep the street manners.
