Shop Holland, JOST or Fontaine 5th Wheel Products

Replace and upgrade your fifth wheel top plate assembly with sturdy aftermarket parts. Filter by popular 5th wheel brands like Holland, JOST, or Fontaine. It’s easy to restore clunk, slack, and vibration with relevant 5th wheel accessories. Add more security with kingpin locks or grab a slider and hinge hardware for better accessibility.

Add Quality 5th Wheel Top Plates & Replacement Hardware

- Lube plates: Reduce friction between the kingpin and hitch plate. - Kingpin locks: Protect your trailer when left unattended. - Pins, clips, and wedges: Keep parts tight and properly aligned. - Rotating pin boxes: Improve turning radius and eliminate harsh angles. - Safety chain loops: Add extra security for your trailer. - Pads and cushions: Minimize wear and absorb shock during towing. - Storage solutions: Keep your hitch accessories organized on or off the road. Whether you’re looking for replacement trailer parts, 5th wheel storage options, or performance accessories, you’ll find reliable options designed to fit your make/model.

How to Choose the Right Semi Truck Fifth Wheel

Start with Your Goal: Replace the top plate/assembly (cracks, binding, worn lock jaw, excessive wear). Reduce clunk/slack (coupling kits, slack reducers, cushions). Improve sliding performance (slider bracket/pins, low-lube plates). Increase security (kingpin locks, safety chain loops). Confirm the Fitment: Do you have a slider (adjustable) or a fixed (rigid) fifth wheel? Is it an air release or manual release (if you’re upgrading)? Are there visible wear points (jaw, wedge, pivot/hinge points)? Remember, you can also purchase inboard or outboard styles, a standard profile or low profile configuration, and various slide bracket sizes depending on whether you have an older, cast-iron style 5th wheel or a lightweight newer model. Need some tips on how to select the right product? Learn about 5th wheel differences in trucks, or call our team for specific in-stock product information.

Frequently Asked Questions About 5th Wheels & Accessories

How do I know which fifth wheel hitch is right for my truck and trailer setup?

The right fifth wheel depends on your truck's frame and rail configuration, the gross combined weight rating you need to support, and the type of trailer you're pulling. Check your truck manufacturer's specifications for compatible mounting systems, and compare that against the weight capacity and kingpin design of the fifth wheel you're considering. If you're unsure, our team can help match a unit to your specific application.

What is the difference between a sliding and a fixed fifth wheel?

A fixed fifth wheel stays in one position on the frame, while a sliding fifth wheel can move forward or backward to adjust weight distribution across the axles. Sliding models offer more flexibility for varying trailer lengths and axle weight requirements, but they typically involve more moving parts to maintain. Your choice should be based on how often you need to adjust axle loads and the type of hauling you do.

How often should I grease or maintain my fifth wheel?

Regular greasing of the fifth wheel plate is essential to reduce wear between the truck and trailer connection and to keep the coupling operating smoothly. Most manufacturers recommend greasing at every trailer hookup or at set mileage intervals, so check your specific fifth wheel's documentation for exact guidance. Routine inspection of the locking mechanism, pivot points, and mounting hardware should be part of the same maintenance schedule.

What accessories are commonly used alongside a fifth wheel?

Common accessories include fifth wheel grease, locking pin covers, air-operated release cables, safety latches, and mounting brackets or rail kits. These accessories help improve ease of use, extend the life of the fifth wheel, and support proper installation. Selecting accessories designed for your specific fifth wheel model helps ensure they fit and function correctly.

Can I install a fifth wheel myself, or should I have it professionally installed?

Installation involves precise mounting to the truck frame and correct alignment with the kingpin, so many owners choose to have this done by a qualified technician or shop with the right lifting equipment. If you have experience with heavy-duty truck components and access to proper tools, self-installation is possible, but improper mounting can affect towing safety and performance. Always follow the manufacturer's installation instructions and torque specifications regardless of who performs the install.
