Brothers Trucks ECM4759 Tubular Engine Crossmember V8 Swap 3-Piece Adjustable

The Brothers Trucks ECM4759 is a heavy-duty tubular steel engine crossmember engineered to facilitate a classic engine swap — converting from an inline 6-cylinder to a small block or big block V8. Built from heavy-wall steel tubing with a durable black painted finish, this crossmember installs directly to the factory framerails either by bolting or welding for a secure, long-lasting fit.

The 3-piece design features slip-over ends with integrated frame flanges, allowing the crossmember to be adjusted to match your specific frame rail spacing. The trim-to-fit construction accommodates a wide range of frame widths, making it a versatile solution for classic truck engine swap builds.

Key Features:

• Heavy-wall tubular steel construction with black painted finish
• 3-piece design with slip-over ends and frame flanges for easy fitment
• Adjustable width from 27 inches to 37 inches to match various frame rail spacings
• Compatible with side bolt motor mounts

Whether you're building a restomod or a high-output street machine, the ECM4759 provides the structural support needed for a clean, professional V8 engine swap installation. Note: some welding may be required depending on application.
