Universal Transmission Crossmember - 3.5in Offs

The Universal Transmission Crossmember - 3.5in Offs by COMPETITION ENGINEERING is a heavy-duty chassis component designed for performance builders and restoration mechanics working on custom or modified drivetrains. This crossmember bridges the gap between your transmission mount points and frame rails, providing essential structural support for upgrades to non-original transmission configurations, engine swaps, or significant powertrain modifications.

The 3.5-inch offset design accommodates modern transmission geometries and engine combinations that deviate from factory layouts, allowing builders to achieve proper transmission height and angle while maintaining adequate ground clearance and chassis balance. The substantial weight of 11.9 lbs reflects its solid steel construction, delivering the rigidity required to prevent transmission deflection, vibration, and premature driveline wear under load or high-horsepower scenarios.

This crossmember is ideal for hot rodders, LS-swap enthusiasts, and classic car restorers installing late-model or non-original transmissions into older frames. However, it is important to verify fitment with your specific frame and powertrain pairing to ensure compatibility.
