Husky Fifth-Wheel King Pin Stabilizers: 33162 vs 33163

A fifth-wheel kingpin stabilizer sits beneath the trailer's front kingpin to help reduce rocking while the RV is parked. Husky makes two closely related tripod models: the 33162 standard stabilizer and the 33163 adjustable stabilizer with a lockable kingpin cup. Both have a 5,000-lb vertical load rating, but their cup arrangement and height ranges are different.

What changes with the adjustable locking cup?

The standard 33162 uses the conventional upper cup. After setting the tripod height using the S-hook chains, its adjustment allows the stabilizer to bear against the parked trailer's kingpin without lifting the trailer.

The 33163 adds a lockable kingpin cup and a separate fine-adjustment feature, with approximately 4½ inches of cup adjustment in Husky's catalog. The locking feature helps deter unauthorized coupling while the trailer is stored. It does not replace the trailer's normal kingpin lock or other security measures unless the manufacturer approves that use.

How to measure before ordering

1. Park and level the fifth wheel on its wheels and landing gear. Chock the wheels.
2. Measure the distance from the ground to the underside of the kingpin where the tripod cup will sit.
3. Compare that measurement with the specified working range: 33–55 inches for 33162 or 34–56 inches for 33163.
4. Ensure the tripod legs have a firm, level surface and clearance around the pin box. Avoid soft ground where the feet can sink.
5. Follow Husky's assembly and adjustment instructions for the chain, S-hook, cup and leg pins. Use the stabilizer for steadiness, not for changing the trailer's level.

Kingpin stabilizer, landing gear or kingpin lock?

These parts serve different jobs. A tripod stabilizer limits movement while parked; the trailer's landing gear carries and raises the trailer for hitching; a kingpin lock helps block unauthorized hitching. Husky's 33161 kingpin lock is a separate security product, not a jack or a replacement for a 33163 adjustable cup.

A tripod's 5,000-lb vertical rating is not the trailer's permitted towing capacity. Do not use either stabilizer to lift the trailer, raise its wheels, replace landing gear or work underneath it. Remove the entire tripod before coupling the tow vehicle or moving the fifth wheel.

For compatible trailer-frame stabilization options, see our Husky RV scissor-jack guide. Scissor stabilizers have different mounting and operating requirements and cannot replace a kingpin tripod directly.
