Receiver Rating: 4,000 lbs
Tongue Weight Rating: 600 lbs
Installation Time: Up to 1 hour

The fourth-generation RX hitch uses six factory attachment points beneath the rear frame. Installation requires removal of the driver-side tow loop and several frame plugs before the receiver can be raised around the dual exhaust and aligned.

1. Removing the Tow Loop and Frame Plugs

We remove the factory tow loop from the driver-side frame rail and return it to the owner. Protective plugs are removed from both frame rails to expose the threaded mounting points.

2. Inspecting the Factory Threads

All six weldnuts are checked and cleaned before installation. This is especially important on older vehicles where road film or corrosion can prevent the structural bolts from threading smoothly.

3. Positioning Around the Exhaust

The receiver is raised between the dual exhaust outlets and aligned with the underside of both frame rails. Two-person support keeps the hitch controlled and prevents contact with the bumper or exhaust trim.

4. Even Hardware Installation

All frame bolts and conical-toothed washers are started by hand before any one side is tightened. This allows the hitch to seat evenly across the factory mounting surfaces.

5. Torque and Appearance Verification

Each mounting bolt is torqued to specification. We confirm receiver alignment, exhaust clearance, secure mounting, and a centered finished appearance beneath the rear bumper.
