Cross Member

The TRANS-DAPT transmission crossmember (SKU TRA4539) is a bolt-on chassis component designed for custom vehicle builds and frame modifications where transmission support and alignment require precision adjustment. Built for builders, restoration specialists, and fabricators working with chassis spanning 26 to 36 inches in frame rail width, this crossmember delivers the structural rigidity necessary to support transmission weight while accommodating engine bay geometry variations. The 3-inch drop design lowers the transmission mounting point, a critical specification when clearance conflicts arise during engine swaps or frame modifications.

Manufactured from welded steel and finished in durable black paint, this crossmember resists corrosion while maintaining structural integrity under dynamic loads. The bolt-on design eliminates the need for welding, allowing field installation without specialized equipment—a practical advantage for technicians working in mobile or shop environments. Weighing 10.5 pounds, the component balances material thickness with weight efficiency, ensuring adequate load capacity without introducing excessive unsprung mass. The 37.75-inch length and 9.25 x 3.75-inch cross-sectional profile accommodate standard transmission bellhousing patterns while the adjustable frame rail width compatibility (26 to 36 inches) provides flexibility across multiple chassis platforms.

This transmission crossmember suits hot rod builders, classic car restorers, and engine swap specialists who require repeatable, code-free support solutions. Installation compatibility extends across multiple transmission types when frame geometry permits, making it invaluable for mid-engine swaps, LS conversions, and rear-engine applications where stock crossmember geometry no longer functions. Proper torque specifications and alignment verification during installation ensure maximum load capacity and component longevity.
