Diffuser (the black part under the rear bumper) Same as in the picture It was installed on my truck with the 5.3 engine, I removed it and installed a diffuser with 4 exhaust cutouts for the 6.2 engine, so I no longer need it > (This is the solid diffuser without exhaust cutouts) In good condition, nothing wrong with it, just some residue inside from where the exhaust was previously installed; I had a sport exhaust installed which was slightly raised, not visible when parked, and everything else is fine Price not set yet, but everything is in good condition I recommend it to you instead of buying a new one because it's expensive, and what I have is original factory made > Reply here to the advertisement or private messages
