FAQs
Will this fit my truck?
This is a universal 3" mandrel-bent elbow for custom fabrication. Verify your tubing OD (3.0") and available clearance before ordering.
Is one end flared or slip-fit?
Yes—these elbows are commonly offered with a flared end to simplify mock-up and assembly. Always dry-fit before final welding or clamping.
Aluminized vs. stainless—what should I pick?
Aluminized is budget-friendly with solid corrosion resistance; T409 stainless is best for harsh climates and long-term durability. See the 3" stainless version: 529006.
How should I install it?
Mock up the run, cut to length, deburr, then weld or use high-quality Torca band clamps (e.g., BC300A, BC300S409). Maintain clearance from wiring, lines, and heat-sensitive components.
