Installation Notes
Verify rotor dimensions, bolt pattern, and rear brake configuration before installation. This part number 604-48037 is listed for rear applications only, and several fitments require specific notes such as 2 Wheel Steering, 4 Wheel Steering, 1-piston rear calipers, or exclusion of limited slip rear axle configurations. Confirm the vehicle’s brake setup against the fitment notes before ordering.
For Chevrolet Silverado 1500, GMC Sierra 1500, and related GM truck applications, match the rotor to the existing rear brake system and inspect pads, calipers, and hub surfaces during service. Proper cleaning of the hub mounting face helps support even rotor seating.
