A leak-free seal where the turbo meets the downpipe.

The Ford 6C3Z-5A231-AA V-Band Clamp is a genuine Ford OE replacement for the clamp that connects the turbocharger outlet to the exhaust downpipe on the 6.0L Powerstroke. It's a small part with a big job: holding a tight, leak-free seal at one of the hottest, most vibration-prone joints in the exhaust system.

Why use a new clamp.

V-band clamps endure constant heat cycling and vibration. Over time they can stretch, corrode or lose clamping force, and reused clamps often don't seal as well as new ones. A fresh genuine Ford clamp restores factory clamping force for a secure, leak-free connection.

Key Features

• Genuine Ford OEM part
• Factory fit and function
• Secures the turbo outlet to the exhaust downpipe
• Restores proper clamping force for a leak-free seal

What Problem Does This Solve?

• Exhaust leaks at the turbo outlet. A worn or stretched clamp can let exhaust escape at the turbo-to-downpipe joint, causing a ticking or puffing noise, soot buildup and exhaust smell under the hood.
• A damaged or seized clamp. Clamps often get damaged or seize during turbo removal. Having a new one on hand keeps your turbo job from stalling.
• Installing a new turbo or downpipe. Many aftermarket downpipe flanges for the 6.0L are designed to use the stock-style V-band clamp, so a genuine Ford clamp is the right fit when installing a new downpipe.

Installation Tip

If you're removing or replacing the turbo, it's a good time to replace this clamp along with the turbo installation gaskets and hardware for a complete, leak-free reinstall.
