Ford Adapter 13/16in - 20 Thread

The Ford Adapter 13/16in - 20 Thread (LONGACRE 52-78412) is a precision measurement adapter engineered for wheel alignment technicians and suspension specialists working on Ford vehicles. This adapter bridges the gap between standard caster/camber gauge equipment and Ford's unique spindle geometry, eliminating the need for expensive alternative gauge systems or workarounds. Built for professional service shops, alignment bays, and dedicated enthusiasts, it ensures accurate toe, camber, and caster readings on Big Ford spindles without modification to either the gauge or the vehicle.

Manufactured from durable aluminum and finished with black powder coat, the Ford Adapter 13/16in - 20 Thread converts a standard 5/16-18 inch gauge bolt to the 13/16-20 inch thread specification required by Ford Big Spindle applications. The precision threading and aluminum construction minimize deflection under measurement load, maintaining gauge accuracy across repeated alignments. At just 0.32 lbs, the compact design—measuring 4.2 x 1.3 x 5.55 inches—fits seamlessly into tight spindle mounting areas without obstructing sight lines or interfering with gauge probe placement.

This adapter is essential for anyone conducting wheel alignments on Ford trucks, SUVs, and performance vehicles equipped with Big Spindle suspensions. Professional alignment shops benefit from having a dedicated Ford adapter on hand to eliminate setup delays and ensure consistent, repeatable measurements across different gauge brands and models. Installation is straightforward: thread the adapter onto the gauge bolt, then attach to the Ford spindle using the 13/16-20 thread. Compatible with all major caster/camber gauge systems that feature standard 5/16-18 inch bolt connections, this single-piece adapter delivers reliability and precision for alignment work that demands accuracy.
