6-14K Hitch L-Bracket Installation For Pole Tongue Trailers

Equal-i-zer® hitch 6K, 10K, 12K, 14K models

This guide covers the installation of standard Equal-i-zer® hitch sway brackets on a pole tongue trailer.  The Equal-i-zer hitch will work with surge brake systems.  If you are installing a 4K hitch model, please refer to the 4K specific installation guide. If this installation method will not work for your particular application, refer to the Equal-i-zer Installation Guide, “Pole Tongue Adaptor.”  You may also contact a customer service representative for support with your installation at 800-478-5578, M-F 8:00am to 5:00pm Mountain time.

Requirements:

  • Clear space along both sides of the tongue from coupler back 38”.
  • Trailer tongue jack must not be mounted closer than 40” from the center of the coupler ball cavity.
  • Additional Hardware:
    • (2) 1/2” x (1-1/4” longer than beam width) – grade 5 hex bolts.  These are only needed if your trailer frame is wider than 2-1/4”.  Otherwise, the 1/2” bolts provided with your hitch will work for this method.
    • Angle grinder or hack saw.

Installation:

Measure and mark 32” back from the center of the coupler ball cavity along the tongue on both passenger and driver sides.  This is the centerplacement mark for the first link plate (second link plate will go in front of this one). See Figure 1. Start with the outside link plate on the passenger side. Insert two 1/2” x 1-1/2” bolts through the outside link plate from the back side.  The head of the bolts should fit completely inside the pocket on the back.

Insert one 1/2” x 3-1/2” bolt through the single hole on the outside link plate, and the single hole on the inside link plate. See Figure 2.

The head of the bolt should fit into the pocket of the outside link plate. Slide on a split washer, and then thread on the 1/2” nut.   Make sure that the bottom bolt is in the hole closest to the bottom of the trailer tongue. See Figure 3.

Pinch the link plates flat and tight to the frame. See Figure 4. Hand tighten both nuts, then use a torque wrench to tighten them to between 50 and 70 ft-lbs torque. Follow the same steps to install the brackets on the driver side. Mount the driver side brackets just in front of the passenger side brackets. See Figure 5.

Place the L-bracket on the two studs through the two middle holes in the L-bracket and check whether the end of the bottom frame bolt sticks out past the L-bracket. If so, grind or cut off just enough of the end of the bolt to prevent interference with the spring bar that will rest on the L-bracket. See Figure 6.

Use the standard Equal-i-zer hitch owner’s manual (LINK) to complete the setup and adjust the height of the L-brackets for proper weight distribution. Once weight distribution setup is complete the L-bracket nuts should be torqued to between 65-75 ft-lbs torque.
