SBF Univ. Motor Mount Crossmember Kit

The SBF Univ. Motor Mount Crossmember Kit (Model 4849) is a precision-engineered tubular K-member designed for small-block Ford engine swaps and frame modifications. Built for automotive enthusiasts, restoration shops, and performance builders who demand structural integrity during engine repositioning or drivetrain upgrades, this crossmember kit provides the rigid foundation necessary to support engine weight and drivetrain loads while maintaining proper frame geometry. Whether you're undertaking a complete engine swap, upgrading to a modern powerplant, or restoring a classic platform, a quality motor mount crossmember is non-negotiable for safe, reliable operation.

Fabricated from high-strength steel with a protective black powder-coat finish, the SBF Univ. Motor Mount Crossmember Kit accommodates frame rails spanning 24 to 37 inches wide, with an engineered 17.250-inch center distance for precise small-block Ford alignment. The tubular construction distributes engine and transmission loads evenly across multiple contact points, minimizing stress concentration and vibration transfer to the chassis. This universally-rated design includes pre-drilled mounting pads that eliminate guesswork during installation, allowing builders to achieve consistent, repeatable fitment across varying frame platforms without custom fabrication or modification.

Fabricators, restoration shops, and serious DIY builders performing small-block Ford engine swaps will find this kit essential for maintaining chassis integrity and engine bay geometry. The adjustable frame-rail compatibility (24–37 inches) makes it suitable for applications ranging from vintage hot rods and street machines to modern restorations where OEM motor mounts are incompatible with engine relocation. Proper installation requires accurate frame measurement and alignment; the 37.75-inch overall length ensures clearance in most engine bays while the 17.95-pound weight reflects the robust steel construction needed for long-term durability under load and vibration.
