Trans-Dapt 4559 Transmission Crossmember with 3-Inch Drop

The Trans-Dapt 4559 transmission crossmember is a bolt-on mounting solution designed to support custom drivetrain installations with a 3-inch drop. It accommodates frame rail widths from 26 to 36 inches, making it suitable for a range of chassis configurations and transmission swap projects. The bolt-on design simplifies installation and helps provide a secure, serviceable mounting point without requiring extensive fabrication.
The crossmember is constructed from durable steel and finished with black paint for a clean appearance and added protection during installation and use. A rubber pad is included to help isolate the transmission mount, reduce vibration transfer, and support smoother operation. The included configuration is designed for practical installation in performance, restoration, and custom vehicle applications where reliable transmission support is required.
Designed for enthusiasts, builders, and professional installers, the Trans-Dapt 4559 combines adaptable frame coverage with a lowered transmission position to help provide additional clearance for drivetrain components, exhaust routing, or other chassis modifications. Verify frame rail width, transmission compatibility, and mounting requirements before installation. This crossmember is supplied as an individual kit and is intended for applications using compatible mounting hardware and vehicle-specific installation procedures.
