⚙️ Step 1 – Preparation

  1. Park the trailer on a level surface and ensure it is secured (wheel chocks recommended).
  2. Verify all parts are included with the bracket kit.


    • 1 – Trailer Bracket (2 parts)
    • 2 – 5/16” bolts x 1.5”
    • 2 – 5/16” bolts x 4”
    • 2 – 5/16” washers
    • 2 – 5/16” nylon lock nuts
    • 1 – 3/8” bolt x 4”
    • 1 – 3/8” washer
    • 1 – 3/8” nylon lock nut


  1. Identify the mounting location on the trailer frame, ensuring adequate clearance for the bracket function.
    • This location should be on the rear cross member of the trailer.

✏️ Step 2 – Mark Mounting Location

  1. Using the tape measure, measure and mark the exact location for the bracket holes.   
  2. Use the tape measure to find the center of the rear crossmember.
  3. Place Trailer bracket in desired location and mark holes.  Confirm alignment so the bracket will sit level and square on the frame.
  4. Confirm trailer backet will operate how it is intended.  If there are any questions, consult with us for proper installation.
  5. Use a marker or center punch to mark drill points.

🔧 Step 3 – Drill Mounting Holes

  1. Select the 3/8” drill bit.
  2. Drill through the trailer frame at the marked locations.
    • Drill slowly and apply steady pressure.
    • Wear safety glasses and gloves.

🔩 Step 4 – Position the Bracket

  1. Place the bracket against the trailer frame, aligning the holes.
  2. Insert bolts through the bracket into the drilled holes.  Use 5/16” hardware here.  1.5” length for I-Beam Trailers.  4” length for Box frame Trailers.

🪛 Step 5 – Secure Fasteners

  1. Use the #3 Phillips screwdriver (for the bolts securing trailer bracket) or socket & ratchet (for bolts/nuts) to tighten the hardware.
    1. Use the 5/16” hardware to fasten trailer bracket to trailer crossmember.
    2. Use 3/8” hardware to fasten Female Threaded piece to trailer bracket.  Ensure the angled cut on the bottom of the Female Threaded piece is facing up.
  2. Ensure all fasteners are tightened evenly and the bracket sits flush against the frame.

 

✅ Step 6 – Final Check

  1. Verify the bracket is securely attached and does not shift under hand pressure.
  2. Inspect all fasteners for proper torque.
  3. Clean up the work area and store tools safely.

⚠️ Safety Note: Always wear safety glasses when drilling. Periodically check fasteners during routine trailer maintenance to ensure the bracket remains secure.
