Product Description
DIAMOND EYE 529011 is a mandrel-bent 90° L elbow in T409 stainless steel with a 3.5" OD. It’s a universal fabrication piece for clean, low-restriction routing on diesel and gas builds—ideal for downpipes, over-axle sections, and tight-clearance transitions.
FAQ: WILL THIS FIT MY TRUCK?
Yes—if you are fabricating a 3.5" exhaust section. This is a universal elbow (not vehicle-specific). Confirm your tubing size (3.5" OD) and available space before ordering.
FAQ: WHAT MATERIAL IS IT?
T409 stainless steel for durability and corrosion resistance in harsh, high-heat environments.
FAQ: HOW DO I INSTALL IT?
Mock up the system, then weld or use quality band clamps. Maintain clearance from brake lines, wiring, and heat-sensitive components.
