The best fifth wheel lube plate depends on the coverage and fit your hitch needs. These products offer a grease-free alternative to applying lubricant directly to the hitch head. The CURT 12-inch plate is best for buyers who want wider coverage; the two-packs suit RVers who want a spare. The listed plates are made from polyethylene or polypropylene, not necessarily Teflon, so check your hitch and kingpin requirements before buying.

scottchen PRO Store 10-Inch Lube Plate, 2-Pack
This two-pack is best for RV owners who want a spare plate available for a replacement. Each disc is made from high-density polyethylene and measures 10 inches across and 3/16 inch thick, according to the product details. Serrated inner teeth are designed to press onto a standard 2-7/8-inch kingpin without tools.
Choose this option if you want a stated pin size, a no-tools installation approach, and an extra plate. The maker recommends replacement every 6 to 24 months depending on use. Check the plate periodically for wear, and confirm that your hitch and kingpin match the listed fit before installation.
Threlaco 10-Inch Fifth Wheel Plate, 2-Pack
The Threlaco two-pack is best for buyers who value having a second plate on hand. The listed material is polyethylene, described as resistant to wear and tear. The product is intended to create a protective surface between hitch components and reduce the need for greasy residue.
Choose it if you want two plates and a straightforward 10-inch option. The provided product details do not specify a kingpin diameter or installation method. Verify fit with the seller or product listing before ordering, especially if your hitch setup has nonstandard dimensions.
TonGass 10-Inch Fifth Wheel Lube Plate
This TonGass plate is best for buyers seeking a single plate made from polypropylene. The listing identifies it as a 10-inch plate for a standard 2-7/8-inch pin. It is designed to reduce friction and wear during towing while avoiding grease residue on the hitch head.
Choose this product if its stated size matches your kingpin and you do not need a multipack. The listing does not give a thickness or replacement interval, so inspect the plate regularly and follow the hitch manufacturer’s guidance for maintenance.
CURT 16722 12-Inch Lube Plate
The CURT 16722 is best for buyers who want a larger-diameter plate. Its 12-inch outside diameter provides more coverage than the 10-inch options in this guide. The product is described as fitting standard fifth wheel kingpins, with inside tabs for a firm, flexible fit. Self-cleaning grooves are also listed.
Choose this plate if its wider coverage suits your hitch head and you want grooves intended to help clear debris. Its larger diameter may not suit every hitch setup, so check available space and the hitch manufacturer’s fit recommendations before purchase.
10-Inch Plate With Grooved Chambers
This 10-inch plate is best for buyers interested in a design with channels and chambers. The listing describes 3D lubrication chambers and grooves intended to capture foreign matter and channel contamination away. It also presents the plate as a grease-free option between the hitch and trailer.
Choose it if those design features matter to your comparison and your setup uses a standard 2-7/8-inch pin, as stated in the product name. The listing’s performance claims are seller-provided and are not independently established here. Confirm fit and inspect the plate for wear during routine hitch checks.
Buying Guide: How To Choose A Fifth Wheel Lube Plate
What size and fit should you check?
Start with your kingpin diameter and the hitch manufacturer’s recommendations. Several products here specify a standard 2-7/8-inch pin, while the Threlaco listing does not provide a pin size. Diameter matters too: the 12-inch CURT plate offers a larger footprint than the 10-inch choices, but you should confirm it fits your hitch head.
Should you choose polyethylene or polypropylene?
Material is one useful comparison point, but it is not the only one. The scottchen PRO and Threlaco plates are listed as polyethylene; TonGass specifies polypropylene. Compare stated dimensions, fit, and features alongside material. The phrase “Teflon plate” is commonly used in searches for fifth wheel lube plates, but the products listed here identify other plastic materials.
Is a two-pack useful?
A two-pack can make sense if you prefer to keep a spare available, as with the scottchen PRO and Threlaco options. A single plate may be enough if you only need a replacement. Regardless of pack size, check the plate’s condition and follow the maintenance instructions for your hitch and product.
Frequently Asked Questions
What does a fifth wheel lube plate do?
It sits between the fifth wheel hitch head and the trailer’s kingpin box to provide a lubricating buffer and help reduce direct friction.
Does a lube plate replace grease?
These products are marketed as grease-free alternatives for the hitch connection. Follow your hitch manufacturer’s instructions, since maintenance requirements can vary by hitch design.
Are these plates made of Teflon?
The supplied listings describe polyethylene or polypropylene, not Teflon. Check the material details rather than relying on the general search phrase “Teflon plate.”
How do I know whether a plate will fit?
Compare the plate’s stated kingpin size and outside diameter with your hitch specifications. Contact the manufacturer or seller if the listing does not give enough fit information.
When should I replace a lube plate?
Replace it when it shows wear or no longer sits securely, and follow the product’s instructions. One listing recommends replacement every 6 to 24 months depending on usage.
