The Mittler Bros. Grand National Floater Rear-End Narrowing Kit is the complete precision tool kit for fabricating a custom Ford 9″ Grand National (GN) floater rear-end housing. Rather than narrowing a conventional rear end, this kit is designed specifically for building a precision floater housing using Mittler Bros. GN snouts — a popular choice for serious drag racing and high-performance street builds where a full-floater axle configuration is required.
The 72″ alignment bar passes through the housing assembly to ensure everything is aligned accurately, squarely, and true before welding. Includes inner blocks for the Ford 9″ floater bore, tube alignment rings to square the housing tube to center, GN snout alignment rings, and a pinion centering plate. Everything you need for a precision floater housing build in one kit. Made in the USA.
