Important Fitment Note
Air compressors can look similar but may vary by mounting pattern, pulley drive setup, shaft length, discharge style, and port orientation. Please compare your original compressor tag number and physical configuration before ordering. If your compressor tag is missing, contact us with your truck make, model, engine information, and VIN so we can help verify the correct unit.
Why Choose a Remanufactured Compressor?
A properly remanufactured TF-500 compressor allows you to replace the failed unit while keeping the correct original-style configuration for your air brake system. This helps avoid unnecessary changes to mounting, plumbing, belt alignment, or air line routing when the original compressor style is still the best match for the vehicle.
Core charge applies. Please retain your old compressor core for return when required.
