    Not for 2002 Chevy 1500HD
  

*by P***  on Reviewed in the United States on May 23, 2023*

They are not for a Checy 2002 1500HD!!! I made the mistake of installing them go to turn the truck on and it makes a big bang and a fire started. Thank God my neighbor saw this and came to my rescue.  I removed them and put the old ones back and it turned on but my truck didn't catch on fire again and need more work done to get it back to the way it was before installing this item.  I do not recommend this product.  I almost burned my truck installing these on it.
