Even if you don't know much about Mustang mods, an S197 strut tower brace install is easy. Follow our step-by-step instructions to see how to install a strut bar in your 2005-2014 Mustang.
Engine Strut bar Install Instructions
For this installation, we chose Ford's Boss 302-style strut brace. It fits all 2010-2014 V6 and GT Mustangs, as well as 2012-2013 Boss 302s. If you have a 2011+ 5-liter and are using a Boss 302 intake, you'll want to perform this exact Mustang strut tower brace install.
Your strut bar might be different from the one we chose, but the installation should be similar for all 2004-2014 Mustangs. Just make sure the brace fits with your engine configuration, and always read the manufacturer's instructions before you install it.
Parts and Tools Needed:
- ⅜” Ratchet
- ⅜” Torque Wrench
- 13 mm Socket
Step 1: Remove Strut Mount Nuts
Open up your Mustang's hood to access the engine. Remove the four strut mount nuts on either side of the engine using a 13 mm socket.
The left strut mount is just in front of the battery. The right strut mount is in the same location on the other side of the engine.
Step 2: Face Strut Brace Forward
Position the strut brace so the arrow is facing the front of your Mustang. Follow the manufacturer instructions that came with your strut bar if you're installing a different brace than ours.
Step 3: Position Strut Tower Brace
Place the new strut brace over the four studs on the strut mounts.
Step 4: Tighten and Torque Down Strut Tower Nuts
Place the strut tower nuts back on the mount and tighten them down with a ratchet.
Next, torque the nuts down to 26 lb-ft with a torque wrench. Repeat this process for the opposite side.
