Specifications

The New Tek 55173 Front Rotor (both sides, 2003-2009) is a direct-fit rotor set designed to restore braking performance to trucks built in those model years. Manufactured from premium cast iron, the rotors are heat-treated and machined to meet strict tolerances for thickness, lateral runout, and parallelism. Each rotor is tested to ensure correct lateral balance and minimal vibration. The dual-side package includes both left and right rotors, allowing full front-axle rotor replacement in one order. With corrosion-resistant coating and precision machining, these rotors are engineered to match or exceed OEM braking characteristics, delivering smooth stops, long rotor life, and reliable performance under demanding driving conditions.
