Transmission & Driveline Chassis Bracing

OEM Transmission Support Crossmembers & Chassis Braces

Restore proper transmission mounting height, eliminate driveline vibration, and ensure safe tail-shaft support with our heavy-duty OEM replacement crossmembers.

The transmission crossmember is a structural steel brace bolted transversely across the vehicle's frame rails to support and secure the rear of the transmission or transfer case. Road salt corrosion, collision impacts, or torn transmission mount rubber pads allow the driveline to sag, causing severe driveshaft angle changes and heavy vibration. Our replacement crossmembers are precision-formed from heavy-gauge steel and include factory bolt-on slotted adjustable mounting provisions.

A collapsed or torn transmission mount rubber pad allows the gearbox to shift under torque, changing the driveshaft operating angle and causing resonant vibration through the floorboard.

Insert a screwdriver and probe all four frame attachment points. If the steel crumbles, flakes, or penetrates easily, the crossmember must be replaced for safe driveline support.

No. A subframe supports the front suspension and engine. A transmission crossmember is a single transverse brace located specifically under the gearbox tail housing at the rear of the transmission.

Yes. A bent crossmember drops the transmission mount point, changing driveshaft operating angles beyond designed U-joint operating range and causing high-speed vibration and premature universal joint failure.

Most crossmembers are sold without the rubber transmission mount pad. We recommend replacing the mount pad simultaneously as a separate item for best results.

Call our team at +1 (855) 613-4411 with your vehicle's VIN, transmission type (Auto/Manual), and drivetrain configuration (RWD/4WD) for exact fitment verification.
