General Installation Notes:
- Confirm there is no interference from the tow vehicle, tongue, ground, or other mounted accessories during all operational positions (stationary or in motion).
- Before installation, check for interference in handle swing and swivel positions, if applicable.
- Verify there is no interference after installation is complete.
Bolt-On Rack Jack Installation:
- Place the gear housing on the tongue and insert the supplied bolts into the corresponding holes for the tongue width.
- Position the mounting bracket below the tongue with the flat surface against it.
- Secure with locknuts and torque to 25 ft-lbs.
Snap Ring/Bolt-Through Instructions:

- Place the jack bracket over the mount and fully seat the snap ring into the groove.
- For Bolt-Through Models:
- Insert the jack bracket into the recessed opening on the mount.
- Place the small end of the bushing into the jack bracket and onto the bolt.
- Tighten the locknut until there is little movement in the bushing.
A-Plate Mounting Instructions (Bolt-On or Weld-On):
- Welding must be performed by an AWS-certified welder.
- Align the jack with the coupler (and foot, if equipped) before welding.
