What This Rotor Set Helps Address

• Brake rotor wear on high-mileage vans and trucks
• Rotor replacement during brake service on front and rear axles
• Brake pulsation caused by uneven rotor surfaces
• Reduced braking consistency from worn disc brake rotors
• Fitment-specific replacement needs on SRW and axle-configured vehicles

Installation Notes

Verify axle configuration, rear wheel setup, gear ratio, and rear disc center hole details before ordering. This part number 4004-48048 is listed for front and rear positions, but the correct application depends on the exact vehicle configuration shown in the fitment data. Compare the existing rotor dimensions and mounting points to the vehicle listing before installation.
