Custom-Bent 3/8″ Round U-Bolts

Our 3/8-inch diameter round U-bolts are custom-bent to your exact specifications. Primarily engineered for suspension, leaf spring, and body mounting, these heavy-duty fasteners are built to be torqued and are not for ornamental use.
We cold-bend our steel U-Bolts on a hydraulic bender to maintain metal grain orientation for maximum strength.

⚠️ Ordering Rules & Pricing

  • Hardware Included: Every price includes Extra Deep Nuts and Hardened Thick U-bolt Washers.
  • How to Price: Select your measurements and the price will be calculated.
  • Non-Returnable: Custom-bent U-bolts are made to order and cannot be returned.

📏 How to Measure Your U-Bolt

Please read these instructions carefully before ordering. Use your product image as a reference:
  • “C” = Inside Width: Measure the exact inside width of the bend.
  • “L” = Inside Length: Measure from the highest point inside to the very bottom of the leg.
  • “T” = Thread Length: Thread lengths are predetermined based on total rod length. (See below Predetermined Approximate Thread Lengths)

💡 Important Length Note: Your delivered “L” measurement may be up to 3/4″ longer than ordered. We calculate total rod length using even numbers (C + (L × 2)) and rounding to the next even length to ensure your U-bolt is never shorter than you need.

🛠️ Fitment & Torque Behavior

  • Spring-Back Notice: Because of the spring-like nature of steel, small-diameter U-bolts (1/2″ and smaller) may measure slightly wider upon arrival.
  • Self-Conforming: When properly torqued, the U-bolt will naturally conform to the shape of the item it fits over.

⚙️ Thread & Rod Specifications

  • Thread Type: We use SAE (fine) threads exclusively.
  • Maximum Strength: Threads are rolled between dies rather than cut for maximum strength.
  • No Re-Threading: The unthreaded stock is slightly smaller in diameter than the threads. They cannot be threaded further by the user.

🔍 Predetermined Approximate Thread Lengths

Use this quick reference chart to find your thread length. If your thread length is a critical measurement, please call us to confirm before ordering.

Total Rod Material Length Thread Length (On Each Leg)
8″ to 20″ 2″ – 3″
22″ to 30″ 3″ – 4″
32″ to 48″ 4″ – 6″
