Notes

• Download the installation instructions (PDF)
• Please confirm your vehicle has the 2014-2018 body style (USA).
• The secondary piece that blocks the 3rd catalytic converter does not fit the regular cab (2-door).
• A heavy-duty threaded rivnut tool with a 5/16"-18 mandrel and a Dremel tool are required for installation — you are simply opening up holes for rivnuts. All other tools required are common.
• Fitment is confirmed for original OEM applications; fitment on lifted, raised, or modified vehicles is not guaranteed.

Pro Tip: Have a quality rivnut tool ready before you start — it is the one specialty tool that makes this installation quick and painless.
