5x5 Rear Hub Kit Steel 2.5

The 5x5 Rear Hub Kit Steel 2.5 from Allstar Performance is a precision-engineered component designed for hot rodders and fabricators building custom rear-end assemblies. This steel hub assembly serves as the foundation for adapting modern wheel fitments to classic vehicles or creating fully custom independent rear suspension (IRS) systems. Whether you're restoring a vintage muscle car or engineering a ground-up performance build, this hub kit provides the structural integrity and dimensional accuracy required for safe, reliable wheel mounting.

Manufactured from steel for maximum durability and heat dissipation, the 5x5 rear hub kit features a 2.5-inch axle bore diameter optimized for compatibility with common hot rod platforms. The 5-lug bolt pattern allows integration with standard modern wheel designs, eliminating the need for expensive custom forging or adaptation rings. Steel construction resists warping under sustained braking loads and thermal cycling—critical for performance driving where aluminum alternatives may flex under extreme temperatures.

This hub kit benefits builders tackling rear-end conversions on older vehicles, bracket-racing platforms, and street rods where OEM components are unavailable or unsuitable. Installation requires proper axle alignment and torque specifications to ensure optimal performance. With its precision-machined surfaces, this hub kit ensures true wheel mounting without run-out, which is essential for tire longevity and steering response.
