Many owners just can’t let go of their truck, and by installing these mods, the old vehicle gets a new life. As GMC Sierra and Chevy Silverado trucks are equally popular in the U.S., GMC and Chevy trucks hood swap is the most popular.

Let’s take a look at how we can interchange the hoods of GMC Sierra HD and Chevrolet Silverado.

  • Step 1:First, remove the bolt and chips that hold the stock grille of the GMC Sierra HD. Be careful while removing that because many people mess things up.
  • Step 2: Then remove the headlights and park lights. Removing these parts are very important for the GMC Sierra hood swap.
  • Step 3: You must remove the front bumper from the framer. Use a proper tool for this purpose. Remove the bumper from the frame and also remove the outer brackets. Without removing the outer brackets, you can’t install a new hood.
  • Step 4: After removing the front end, you must clean the area properly. Spray a coat of good quality rust that encapsulates paint on the radiator support. Make sure the paint covers every bit of radiator support.
  • Step 5: Then, remove the hood and put it on the work table. Mark it with a tie strap to indicate the body lines of the hood.
  • Step 6: Use some tape and heavy paper to mark a template. This step is very important to align the template with the Silverado hood. Use the same tie strap to compare the GMC hood and Silverado hood.
  • Step 7: Use the template you made from the GMC hood. Transfer the entire pattern to the Silverado hood.
  • Step 8: Flip the hood to check if you need to make a patch. You may need to make a patch to ensure the integrity of the leading edge of the wood. Make a paper pattern, fill the gap and double the hood edge.
  • Step 9: Cut the pattern from 18-gauge steel. Trim it until it fits perfectly and weld it in the right place.
  • Step 10: If you need to maintain a consistent leading edge of the hood, you can use a metal coat hanger. It may sound odd, but it gets the job done.
  • Step 11: After welding the rod, find the leading edge in the right shape and install it open the truck. Use primer and self-etching polymer on the work area to prevent any sealant leakage. Check if everything fits properly and install the hood on the GMC.
