Brake Rotor Hub Inboard Splined Black Aluminum

The Ti22 PERFORMANCE Brake Rotor Hub Inboard Splined Black Aluminum (TIP4025) is a precision brake adapter engineered for high-performance vehicles requiring reliable rotor mounting conversion. This inboard splined hub translates 2.910 x 46-spline axle interfaces to an 8 x 7.000-inch rotor bolt pattern, enabling seamless drivetrain compatibility across custom builds, race applications, and specialty vehicle platforms where OEM brake geometry requires adaptation.

Constructed from black-anodized aluminum, this hub delivers the rigidity necessary for consistent brake engagement while maintaining a lightweight profile—critical for applications where unsprung weight directly impacts suspension response and vehicle dynamics. The 2.07-pound spec reflects the material efficiency that aluminum provides over steel alternatives, without compromising the structural demands of inboard rotor mounting. The spline design ensures positive engagement with no slip or play during acceleration, braking, or cornering events where lateral forces could otherwise introduce drift or inconsistent pad contact.

This adapter serves drivers and fabricators building custom drivetrains, off-road recovery platforms, sand rails, and performance vehicles where factory brake architecture must be reconfigured to match non-standard axle diameters or bolt patterns. Ti22 PERFORMANCE components are recognized in motorsports and serious enthusiast circles for dimensional accuracy and repeatability—specifications that matter when brake systems demand zero tolerance for misalignment.

Brake rotor adapters are essential components in custom drivetrain work; unlike generic spacers, a purpose-engineered hub maintains the thermal transfer path and centering geometry that modern braking systems depend on. The 46-spline to 7.000-inch bolt circle conversion is a specialized dimension set—verification against your specific axle and rotor specifications is essential before installation.
