5in Steering Hub Extension

The 5in Steering Hub Extension by Chassis Engineering is a precision-engineered steering column spacer designed for hot rod builders, classic car restorers, and custom vehicle fabricators who need increased clearance between the steering wheel and dashboard. This extension addresses a common fitment challenge when installing oversized steering wheels, relocating engine components, or modifying firewall positioning in tight engine bays. Whether you're working on a street rod, restomod, or custom fabrication project, this hub extension provides the offset necessary to achieve proper ergonomics and clearance without compromising steering geometry.

This steering hub extension features a robust design that maintains concentricity and steering column alignment while adding 5 inches of longitudinal offset from the original hub mounting point. The compact dimensions (4.3 x 3.4 x 7.9 inches) and lightweight construction at 0.85 lbs make installation straightforward without adding undue mass to your steering assembly. Chassis Engineering's manufacturing standards ensure precise tolerances that prevent binding, wobble, or play in the steering column—critical factors for maintaining responsive handling and safety in high-performance or custom applications where steering feel directly impacts driver control.

This extension works best for builders upgrading to larger diameter steering wheels (14 inches and above) or those repositioning engine components that encroach on the original column space. Installation requires basic mechanical skill and compatible with most aftermarket steering columns and U-joint assemblies that use standard hub connections. Fabricators often pair this extension with custom column brackets and adjustable column support kits to maintain proper column angle and reduce steering effort while preserving the vehicle's handling characteristics. Verify your specific steering column manufacturer's recommendations before installation to ensure compatibility with your build.
