One of the biggest complaints of the new S550 was that the the 2015 Mustang hoods still used a prop rod instead of hood struts. Luckily, the aftermarket has come to the rescue with hood struts for S550 Mustangs. Follow along as we walk you through how to install hood struts on 2015-2023 Mustangs.

How To Install S550 Mustang Redline Tuning Hood Struts

Tools Needed:

  • 13MM Socket
  • Center Punch
  • Drill
  • 3/8” Drill Bit
  • ¾” Drill Bit
  • Round File or Countersink Drill Bit

Driver’s side:

  1. With the hood up, locate the oval-shaped hole on the driver-side fender close to the strut tower.
  2. Take one of the fender brackets and place the supplied bolts through the bracket.
  3. Thread one of the red inserts onto the bolt just a few turns with the insert and bracket facing the same way.
  4. Tilt and slide the red insert into the oval hole in the fender with the ball stud facing the outside of the car.
  5. Tighten down with the 13MM socket while pulling up on the bracket.

To install the top ball stud bracket:

  1. Locate the first nut on the hood hinge closest to the front of the car and remove that nut with the 13MM socket.
  2. Using the left hand hinge bracket, slide it over the hinge stud and rotate it so that it is against the hinge and the ball stud is facing the engine.
  3. Re-install the factory nut.
  4. Next, using the body end of the hood strut, push the top into the ball stud on the hood.
  5. Release the factory prop rod and install the lower portion of the Redline hood strut and make sure both ends are securely in place.
  6. Secure the factory hood prop back into place to support the hood.

Moving to the passenger side

  1. Install the hood bracket just as you did on the driver’s side and make sure the bracket is securely against the hinge and ball stud is facing the engine and tighten down with a 13MM socket.
  2. To install the lower bracket, the battery cover will have to be removed. Locate and remove the push pin closest to the passenger side fender holding part of the battery cover.
  3. Place the supplied drill guide over the hold and install the push pin to hold the drill guide in place.
  4. Rotate the drill guide where the hook portion is flush against the battery cover. (If you have any questions about the placement, please refer to the video or give one of our experienced customer care representatives a call.)
  5. Hold down the guide and place a small mark using a center punch through the small hold in the guide.
  6. Remove the push pin and guide.
  7. Using a 3/8” bit as a pilot, carefully drill through the battery cover.
  8. Remove the battery cover all the way and clean up the hole using a file or countersink bit.
  9. Now, install the fender bracket the same way you did on the driver’s side with the ball stud facing the outside of the car and tighten down with a 13MM socket.
  10. Re-install the battery cover and hood pins.
  11. Install the hood strut the same as the driver’s side.

Now you can store the factory hood prop or remove it altogether.

What's up everyone. Landan with latemodelrestoration.com. If you've opened the hood on your 2015 Mustang, you're probably scratching your head as to why Ford still uses a prop rod. Because honestly, I'm thinking the exact same thing.

No worries. The folks over at Red Line Tuning offer two great solutions to rid that out-of-date, annoying prop rod. Each kit installs effortlessly, features powder-coated hardware, and are available in a plus or elite option.

The plus offers a black e-coated finish, whereas the elite will be made from type-316L polished stainless steel. Each hood strut will feature a progressive, slow-release system, which uses the gas springs to slow down the extending right, allowing for a fluid lifting process.

Both the plus and elite hood struts will fit all 2015 EcoBoost, V6, and 5.0 mustangs. Now, let's go ahead and show you how to install your Red Line Tuning hood struts onto your 2015 Mustang.

With the hood open, start by locating the oval shaped hole near the top of the fender on the driver's side. Next, slide one of the included bolts into the fender bracket. Then, thread one of the red inserts onto the bolt with the flat end facing toward the bracket. Be sure and leave some room between the bolt and bracket so you can carefully tilt and slide the red insert into the hole in the fender. Make sure the ball stood on the bracket is facing towards the outside the car. Pull up on the bracket and tighten the bolt with the 13 millimeter socket.

Still working on the driver's side, locate the hood hinge and remove the top nut with a 13 millimeter socket. Using the included left-hand hood bracket, slide it over the stud and rotate it clockwise until it touches the outer flange on the hood hinge. Then, tighten down the factory nut.

Next, install the body portion of the hood strut on the ball stud at the hood hinge. Then, release the prop rod and install the lower portion of the hood strut onto the ball stud at the fender. Be sure and remember to secure the hood prop when finished with the driver side.

Moving to the passenger side, start by installing the hood bracket the same way you do on the driver's side. To access the fender hole on the passenger side, the battery cover will have to be removed. Start by removing the push pin closest to the fender. Then, align the included plastic drill guide with the outer edge of the battery cover and reinstall the push pin. Hold down the plastic guide and place a mark through the small hole with a center punch. Since it requires a 3/4 inch hole, I would recommend starting with a smaller but first. We chose to use a 3/8 inch bit as our pilot hole. Be careful not to apply too much pressure on the battery cover when drilling.

Once the hole is drilled, remove the two other push pins holding the battery cover down the same way you did the first one. Remove the battery cover and clean up the drilled hole with a countersink bit or file. Then, install the fender bracket the same way as the driver's side, with the ball stud facing toward the outside of the car. Reinstall the battery cover and push pins.

Install the hood strut the same way as the driver's side, and then you're all finished. Installation should take you about 15 to 20 minutes, and can be done right in your garage.
