Dyna-Flo® HMW Lube Disc eliminates King Pin Plate grease and Fifth Wheel lubricants. Dyna-Flo® HMW Lube Disc slides over king pin and is attached by the included spring washer. These 32″ diameter x .170 thick lube disks are easily installed on existing king pin plates.
Eliminate messy grease to lubricate your 5th Wheel. A large surface gives extra protection from wear and tear of normal towing. The slick disc is made from space-age material and mounts on the king pin plate. Furthermore, installation is a snap, just slide it on and the unique “finger” design spring washer holds it in place. Hence, no holes to drill. Never use grease on your 5th Wheel again, rather install the slick disc and forget about getting greasy.
