55-57 Chevy Pivoting Floor Mount

The 55-57 Chevy Pivoting Floor Mount from BORGESON is a precision steering column bracket engineered for builders and enthusiasts restoring or customizing classic Chevrolet full-size cars from 1955 to 1957. This deluxe swivel mounting solution addresses a critical need when fabricating custom steering geometries, upgrading to modern steering boxes, or repositioning the column to accommodate engine bay modifications. Whether you're executing a frame-off restoration, installing a rack-and-pinion conversion, or adapting a non-original steering system, this pivoting floor mount delivers the adjustability and structural integrity required for safe, reliable steering operation.

Constructed from high-grade aluminum in a polished finish, the 55-57 Chevy Pivoting Floor Mount accommodates a 2-inch diameter tube, allowing integration with standard chromoly or DOM tubing steering columns commonly used in hot rod and restomod builds. The swivel design grants pivoting adjustment around the mounting axis, enabling fine-tuning of column angle and fore-aft positioning without requiring full structural rework. The rigid mounting plate bolts securely to the vehicle's floor pan, distributing side loads and feedback forces evenly to prevent steering column whip and vibration—critical factors for both street and track use. At just 0.72 pounds, the aluminum construction minimizes unsprung weight while maintaining the durability expected in high-performance driving scenarios.

This bracket is ideal for vintage Chevy restorers, custom hot rod builders, and fabricators tackling steering system upgrades on 1955–1957 full-size models. The pivoting action simplifies mock-up and final fitment during the build phase, reducing time spent on trial-and-error column positioning. Installation is straightforward for builders with basic welding and mechanical skills, though floor pan reinforcement may be necessary depending on the total steering load and driving conditions. The polished aluminum finish integrates seamlessly with period-correct or modern aesthetic builds, and the compact footprint (6.05 x 1 x 8.8 inches) fits snugly in tight engine bays typical of mid-1950s Chevy architecture.
