A CURT 5th wheel wedge is a simple but reliable way to allow a CURT 5th wheel hitch to be used with a rotating 5th wheel pin box. A pin box mounts on top of the 5th wheel head and provides a new pivot point for the kingpin and wider turn radius for the 5th wheel trailer. To keep the pin box from swiveling in its 5th wheel mounting location, a 5th wheel wedge inserts into the hitch head, locking the pin box into place. This 5th wheel wedge is designed to fit any CURT A-series 5th wheel hitch and accommodates select models of the Sidewinder* pin box. It comes with all necessary hardware and features a durable carbide finish for rust-resistance.

CURT part 16992 is designed for A-series 5th wheel hitches. If you have an E-series hitch, you need part 16991 instead. Verify your hitch series before ordering.
You need a ratchet and socket set. The installation is rated as Easy difficulty.
The kit includes one 5th wheel wedge, two 5/8" hex bolts, and two 5/8" lock washers.
Tighten both 5/8" bolts to 150 ft-lbs torque after uncoupling the trailer.
Yes. Apply grease to both sides of the wedge and skid plate during Step 1 of installation.
Before every tow, ensure all fasteners are tight, the 5th wheel jaws are locked around the trailer king pin, the safety pin is installed on the locking handle, trailer lights and brakes work, and the trailer weight does not exceed the hitch rating.
The CURT 16992 is a 5th wheel wedge that attaches to the pin box of an A-series 5th wheel hitch. It is tapped into the skid plate to help secure the coupling between the towing vehicle and trailer.
Attach the wedge to the pin box using two 5/8" bolts and two 5/8" lock washers. Tighten the hardware until the lock washers begin to engage. Do not fully tighten at this stage.
1. Attach the wedge to the pin box with two 5/8" bolts and lock washers, tightening until lock washers engage. 2. Apply grease to both sides of the wedge and skid plate. 3. Couple the trailer following the 5th wheel hitch manual. 4. Tap the wedge into the skid plate as much as possible with a rubber mallet. 5. Tighten one or both bolts if accessible. 6. Uncouple the trailer. 7. Tighten both 5/8" bolts to 150 ft-lbs torque.
Yes. After attaching the wedge and applying grease, couple the trailer following the 5th wheel hitch installation manual. Then tap the wedge into the skid plate with a rubber mallet and tighten accessible bolts. Finally, uncouple the trailer and tighten both 5/8" bolts to 150 ft-lbs torque.
Use a rubber mallet to tap the wedge into the skid plate as much as possible during Step 2 of installation.
Initially, tighten the 5/8" bolts until the lock washers begin to engage. Do not fully tighten at this stage. The final torque of 150 ft-lbs is applied after uncoupling the trailer.
Never exceed the vehicle manufacturer's recommended towing capacity. The manual does not specify a capacity for the wedge itself; refer to your vehicle and 5th wheel hitch documentation for the applicable limits.
No. Do not tow a trailer with worn or damaged parts. Before every tow, ensure all fasteners are tight and all structural components are sound.
Visually confirm that the 5th wheel jaws are locked around the trailer's king pin before towing. Also ensure the safety pin is installed on the 5th wheel locking handle.
Load the trailer so the weight is heavier towards the front of the trailer without exceeding the hitch vertical weight rating. Never load the trailer heavier behind the trailer axle(s). Ensure the load is secured to prevent shifting and centered from left to right.
Before every tow, ensure all fasteners are tight and that all structural components are sound. The wedge and skid plate should be greased during installation. The manual does not specify a maintenance interval for regreasing.
