TonGass (2 Pack, Black) 5th Wheel Lube Plate
Best for budget-conscious buyers who want real value. This 2-pack uses a durable PP plastic plate to reduce friction and wear between the kingpin and plate, extending hitch life without greasy residue. It’s a straightforward, no-muss option for occasional to moderate tow distances. Best for: campers who want a pair of plates for backup or extended trips. Caution: PP plastic may show wear sooner under heavy, frequent high-mileage towing compared to higher-grade materials.
scottchen PRO 5th Wheel Lube Plate 10″ White
Best for weekend campers who want a clean, grease-free experience. The white polyethylene disc provides a smooth lubrication barrier between kingpin and plate, keeping the bed clean and hands grease-free. No tools required for installation—simply press onto a standard 2-7/8″ pin. Caution: designed for standard kingpins; measure pin size if your setup differs, and expect replacement every 6-24 months depending on use.
scottchen PRO 5th Wheel Lube Plate 10 Inch Black
Better for reducing noise and adding cushion during towing. This black 3/16″ thick HDPE plate creates a barrier that dampens metal-on-metal friction and minimizes chucking sounds. It fits most standard 5th wheel hitches with a 2-7/8″ kingpin. Best for: travelers prioritizing quieter towing and smoother rides. Limitation: ensure correct pin box measurement; the product line notes a 12-inch version if your pin box is larger than standard.
Threlaco 2 Pack 5th Wheel Lube Plate 10 Inch White
Best for buyers who want a spare plate and broad protection. This 2-pack offers a large contact surface that reduces friction and wear, prolonging the hitch life while keeping towing tidy and grease-free. Made from durable polyethylene for longevity. Caution: confirm your kingpin diameter and pin box size to ensure a proper 10-inch fit with a 3/16″ thickness.
Buyers Products FWD32, 32 Inch Fifth Wheel Lube Disk
Best for professional fleets and heavy-use rigs seeking a large, self-lubricating disk. The 32-inch disk eliminates grease mess and uses durable polymer to reduce friction and wear on towing components. It includes a steel retention clip to secure the disk in place. Choose this if you need broad coverage across larger hitch surfaces and durable retention. Caution: larger size requires compatible pin box geometry and mounting clearance.
CURT 16722 5th Wheel Hitch Lube Plate
Best overall coverage for standard hitches with easy maintenance. The 12-inch diameter provides substantial surface coverage, with self-cleaning grooves to reduce residue. It’s designed to be wear-resistant and compatible with standard kingpins, delivering a consistent lubrication layer. Caution: verify pin box size and hole compatibility for your specific hitch model. This option prioritizes broad protection and clean coupling.
Threlaco 2 Pack 5th Wheel Lube Plate 10 Inch Black
Best when you want a spare ready-to-use plate with strong wear resistance. The 3/16″ thick polyethylene plates provide durable cushioning and friction reduction for long trips. Choose this for redundancy and quick swaps during extended travel. Caution: verify pin box and kingpin size to ensure a proper 10-inch fit with your existing hitch.
Buying Guide: Key Purchase Considerations
What matters most when selecting a fifth wheel slip plate? Consider material, fit, and friction reduction. Materials like HDPE and durable polyethylene offer low-friction surfaces and wear resistance. Check the diameter and kingpin compatibility (most 10-inch or 12-inch options fit standard hitches). Durability and thickness affect long-term performance; thicker plates can damp more noise and vibration. For maintenance-free operation, look for “no-grease” solutions that eliminate petroleum-based mess. If you tow frequently across long distances, plates with larger contact areas and secure retention clips help prevent shifting.
Is a 10-inch plate enough for my hitch?
Most standard fifth wheel hitches use a 2-7/8″ kingpin with a 10-inch or 12-inch lube plate diameter. Measure your pin box surface and compare to the plate’s diameter to ensure full coverage. A larger plate can offer better protection on bigger setups, but must fit your specific hitch geometry.
Which material should I choose?
HDPE and other high-density plastics provide good durability and low friction. Polyethylene plates tend to resist rain, snow, and dust, making them suitable for all-season towing. Polypropylene variants are often budget-friendly but may wear faster under heavy, repeated use.
How often should I replace a lube plate?
Replacement intervals depend on usage, mileage, and conditions. Many manufacturers suggest replacements every 6-24 months for standard use, but high-mileage or harsh conditions can shorten this timeframe. Look for visible wear, cracks, or signs that the plate no longer evenly covers the kingpin surface.
What about installation ease?
Many modern plates offer tool-free installation by simply pressing onto the kingpin. If installation requires more than pressing, verify compatibility with your hitch type and whether any additional hardware is needed.
FAQ
- Q: Do slip plates completely replace grease on the hitch?
- A: They reduce the need for grease by providing a washable, low-friction barrier between the kingpin and plate.
- Q: Will a slip plate fit all fifth wheel hitches?
- A: Most are designed for standard kingpins (2-7/8″ diameter) and common hitch plates; always verify compatibility with your specific model.
- Q: Can I use a slip plate with a rail-mounted hitch?
- A: Yes, but confirm plate diameter and clearance to ensure full coverage without interference.
- Q: Are slip plates easier to maintain than grease-based options?
- A: Yes, most no-grease plates minimize residue and simplify wash-downs after towing.
