Brake Rotor Adapter for 2-7/8in Smart Tube Hub

The Brake Rotor Adapter for 2-7/8in Smart Tube Hub (Model CRC-2057A) is a precision-engineered conversion component designed for operators who need to interface non-standard brake rotor bolt patterns with 2-7/8-inch smart tube hub assemblies. This adapter solves a critical compatibility gap in custom vehicle builds, military fleet maintenance, and law enforcement tactical vehicle configurations where OEM rotor mounting patterns don't align with aftermarket or specialized hub architectures.

Manufactured from hardened steel with black paint finish by Diversified Machine, this adapter converts a 5 x 5.00-inch bolt pattern (common on many truck and Humvee platforms) to an 8 x 7.000-inch rotor bolt pattern, enabling secure rotor mounting without drilling or hub modification. The adapter weighs 1.33 pounds and measures 7.7 x 0.3 x 7.75 inches, positioning it as a lightweight yet rigid solution that maintains brake system integrity under high-stress tactical operations, pursuit driving, and heavy off-road use. The multi-bolt design distributes clamping force evenly across the mounting surface, reducing stress concentration and extending rotor life in demanding conditions.

This adapter is essential for armored vehicle technicians, custom tactical vehicle builders, and military motor pool personnel tasked with retrofitting brake systems on specialized platforms where standard rotor mounting cannot be used. Installation requires removal of the hub assembly and careful alignment of both the adapter and rotor bolt holes; torque specifications should follow your vehicle manufacturer's recommendations for the 2-7/8-inch hub system. Operators and mechanics familiar with brake system service will find this component straightforward to install, though professional installation is recommended to ensure proper rotor runout and braking performance, particularly on high-duty vehicles where brake failure is not an option.
