On 1994–1997 OBS 7.3 Powerstrokes, the upper heater hose routing can get sloppy over time. When it droops, it doesn’t just look messy—it can rub on alternator wiring/connectors and create a wear spot that turns into an electrical short. This bracket exists to stop that.

Why use this over the OE bracket

The factory setup is commonly described as flimsy sheet metal (or it’s simply missing on a lot of trucks), which is why owners end up with the heater hose rubbing where it shouldn’t. 

What the Riffraff bracket is

(Part number: RDP-HH-BRKT)

• 6061 aluminum
• Hard anodized for long-term durability
• Stainless clamp hardware included
• Available in multiple colors
• Made in the USA
• What it fixes (the practical benefit)
• Secures the heater hose so it stays off the alternator wiring/connectors (prevents chafing and potential shorts).
• Cleans up the engine bay and keeps routing consistent (owners also mention it holds the hose up and out of the way better than the OEM setup).

Installation:

Loosen the appropriate alternator/accessory bolt, position the bracket, snug it down, route the heater hose through the clamp, tighten the clamp, then verify clearance at the belt, wiring, and boost tube through a full engine rock.

Quick tip: some customers report the bracket works best with a slightly longer bolt (the stock alternator bolt will work, but may feel short).
